Update: We've heard from some readers who thought that the first updated "Blue Marble" photo was of the same region of the planet as the image. That's not the case. The Apollo 17 crew took a photo, left, which extends from the Mediterranean Sea area to the Antarctica south polar ice cap. There is heavy cloud cover in the Southern Hemisphere, while the coastline of Africa is visible.
The Asian mainland is on the horizon toward the northeast. The image taken on July 6, , center, was of the other side of the planet and North and Central America are most clear. On July 29, a third "Blue Marble" image, right, was released that shows Africa front and center.
Central Europe is toward the top of the image with the Sahara Desert to the south. He explained what makes these images so special. Along with the challenge of getting far enough away to get the entire Earth into a single frame, there is the matter of lighting. Consequently many of the images of Earth we see are actually composites. This is just the first in a series of images of Earth that will be sent back from a million miles away.
We will soon see the other side, fully illuminated as well. Update: you can find the other side here. Jerrold T. Bushberg, a medical physicist and a professor of radiology and radiation oncology at the University of California, Davis on the risks of radiation emitted by cellphones. A Berkeley, Calif. This photo shows an stockpile of elephant and rhino tusks that have been seized by the Kenyan government. Scientists gathered data about the collection at Kenya Wildlife Services headquarters in Nairobi on Tuesday. More than two decades after a ban on ivory trade, Asian demand still fuels illegal poaching of elephants and rhinos in Kenya.
The Kenyan government has said that it wants the world to see these animals for their beauty rather than economic gain. It should always be happening in the background. This is the biggest question. We should be listening. Forty six years ago, Neil Armstrong and Buzz Aldrin landed on the moon. Mueller, a NASA official. Mueller attempted to forecast the next decade of American missions to space. Some of what the NASA official proposed - an orbital space station serving as a laboratory and reusable shuttles - eventually came to pass.

But much of what he hoped for did not occur:. The essay described the advantages of a nuclear-powered base on the moon that would create a breathable atmosphere and house explorers. A couple of months ago, humanity did succeed in sending an espresso maker to the International Space Station. But we've yet to build an extra-terrestrial base. Mueller proposed spacecraft with nuclear-fueled engines that would remain in orbit and transfer personnel from a station orbiting Earth to one that would orbit the moon, and then to the moon itself.
As the recent Pluto mission has demonstrated, securing enough nuclear fuel for a piano-size spacecraft is still a challenge. The essay concluded: "By the end of this decade the moon could be, and I believe will be, regularly visited. The Cuban hutia, a button-nosed, furry rodent the size of a dachshund, is said to be shy by nature. They greeted us when our skiff reached the beach, and were happy to stick around for a drink. While some might see them as oversized rats, these hutias were pretty cute.
It lives on plants, fruit and the occasional small reptile, but has a special fondness for mangrove roots. It is illegal to hunt hutias in Cuba without a special permit, but occasionally they end up in stew. Legend has it that the rodent provided the first meat Christopher Columbus tasted in the New World. Some confusion has arisen about how to pronounce the name of Pluto's main companion, Charon. We talked about it with James Christy, who discovered Charon by seeing Pluto looking suspiciously elongated on a photographic plate back in Christy, an astronomer at the United States Naval Observatory at the time, decided to name the new object after his wife Charlene, whose nickname was Char.
And so, he and she maintain, the moon's name should be pronounced Shar-on with the sh like Cher , not chair and the ar like bar , not Karon or Chair-on as some commentators have said. You can hear him say Charon here and explain the moon's origin story here. Christy added "but mine delivered.
An earlier version of this post misspelled the surname of the wife of the discoverer of Charon. She is Charlene Christy, not Christie. Additionally, a caption with an earlier versio of a photograph with this post misstated the first name of Ms. She is Charlene, not Charon. At first glance, it's a picture of Earth. Not much different from all those pictures of Earth you've seen over the years. There are not many photographs showing a fully illuminated Earth, because the camera has to be between the Earth and sun, while far enough away to capture the whole planet.
Weather satellites in geosynchronous orbit can get a similar view, but not quite the entire hemisphere. Also, they are over a single location and the planet is partly in shadow most of the time. Now, the Deep Space Climate Observatory , or Dscovr for short, will be taking such photographs on a regular basis, always over the dayside of Earth. The first was released on Monday. The spacecraft started out as "Triana," a pet project of former Vice President Al Gore in who thought it would be inspirational and educational for a satellite to continually send back a view of a changing Earth from almost a million miles away.
Opponents derided it as "GoreSat," and the finished spacecraft was put in storage. It was resurrected by the National Oceanic and Atmospheric Administration to look the other way, at the sun, to serve as a sentinel of oncoming solar storms. But the Earth-facing camera is still there and now is finally taking pictures. She died at age 56 on July Scientists had a lot riding on the New Horizons mission to Pluto. First, there was the audacious expectation that a spacecraft launched nearly 10 years ago would go exactly where it was expected to go, billions of miles away.
Second, there was the belief that what we'd learn from the dwarf planet would make all the waiting worthwhile. Later today, we'll find out whether the latest images of Pluto and its moons can take our breath away again. That will certainly include more stunning photographs like the close-up snippet of Pluto's surface that came out on Wednesday.
That is likely what Jeffrey Moore, the lead of the mission's geology and geophysics team, will talk about. The news will probably go beyond the photographs to some of the more esoteric data. Her expertise is how the solar wind — the stream of charged particles spewed by the sun — behaves when it intercepts a planet or dwarf planet like Pluto.
The news conference will also feature Randy Gladstone, the head of the atmosphere team, perhaps providing some information about Pluto's thin air, which like Earth's is mostly nitrogen. The dynamics of the atmosphere probably have a lot to with the wide variations in brightness on Pluto's surface.
Exactly fifty years earlier, NASA pulled off a similar feat when the Mariner 4 spacecraft sent home the first images of Mars. The photos were featured at the top of the front page of The New York Times on both days. Quite a bit has changed in the succeeding decades, but the differences in the speed at which the photos made it home are particularly remarkable. An article in The Times in noted that it took eight and a half hours to send a single image from Mars to Earth, at a speed of 8.
Patience was still required to receive a single image from Pluto, but across a distance of billions more miles from Earth, New Horizons was sending us images at 1, bits a second. However long it took to see those images for the first time, on both days, readers of this paper could take delight in finding an otherworldly scene delivered directly to their doorsteps.
Andrea Di Giulio, an entomologist at Roma Tre University, on his study of a parasitic beetle species. He was there nine and half years ago when New Horizons headed off to Pluto. In , the United States issued a set of 10 stamps: one for each planet plus for one for the Earth's moon. The stamp for Pluto showed a blurry globe with a simple statement: Not Yet Explored. Among the memorabilia on the New Horizons spacecraft is one of those Pluto stamps, by far the farthest that 29 cents of postage has ever traveled.
It took ten years and 4. McNutt's physicist father, Ralph McNutt, was working on the mission. The images will have 10 times the resolution of the photo of the icy planet released on Tuesday. NASA might also release a 3D image of some part of the planet's surface along the lines of this landscape from Mars. Get your 3D glasses ready! It could provide the lesson plan for a master class in energy efficiency all by itself.

That is to be the first communication from the spacecraft in 22 hours. It will not include any photographs. A little more patience is required for those. Jason Drakeford , a New York Times video producer, and the cosmic affairs correspondent Dennis Overbye talked with Bill Nye as they waited for the call. Nye's exploratory priority: looking for life beyond. They also captured the grand celebration as the spacecraft flew by Pluto, the culmination of more than a decade of careful planning.
One of them may have donned a strange hat. Earlier this week we asked our readers to vote on what they think NASA should explore next. Astronomers have long flirted with the idea that Jupiter's moons could harbor the ingredients necessary for life. Previous findings have suggested that oceans exist beneath the surfaces of Jupiter's moons Europa, Callisto and Ganymede. Tyson said.
Cecil The Lion’s Son Has Been Shot Dead, And All For Nothing
Early proposals favored sending a spacecraft to orbit the moon. But NASA decided against that because radiation from Jupiter engulfs Europa, and an orbiter would probably be fried if stayed too close to the moon for too long, the researchers said. Instead, they have proposed sending the spacecraft to orbit Jupiter from a safe distance away from the radiation and then perform frequent flybys of Europa.
The craft will perform about 45 of these maneuvers during its three-year mission, according to NASA. Like Dr. Tyson, NASA's astronomers hope the spacecraft will provide tantalizing details about the potential for life to exist elsewhere in our solar system. The agency plans to launch the mission in the s. New Horizons was 72 seconds early to its chilly destination. New Horizons will send back at least one higher-resolution image on Wednesday, but the rest of the photos will remain stuck on the spacecraft for months.
Imagine someone speaking to you softly from the other side of a large room. You might be able to barely hear him but to make out the words if he spoke very, very slowly. Its radio transmitter puts out a tiny 12 watts of power, about the same as an LED bulb in a table lamp. Even with a huge meter radio dish on Earth listening to the faint transmissions, that means New Horizons has to talk very, very slowly. As New Horizons starts sending its trove of flyby data back on Wednesday, the pace will be at a glacial 1, bits a second. That is roughly the rate at which computer modems talked to each other in the mids.

Photographs taken by the spacecraft's black-and-white camera measure 1, pixels by 1, pixels, or more than a million pixels in total. Each pixel consists of 12 bits, to record one out of 4, possible gray levels. That's more than 12 million bits of information in each picture. To send that all back at 1, bits a second would take 12, seconds, or 3 hours and 20 minutes. Images can be compressed, but even if squeezed to a tenth of the original size, one photograph would still take 20 minutes to download.
New Horizons is taking a lot of pictures and collecting a slew of other measurements, too — so much that it would take three months to send all of it back if New Horizons could get exclusive use of NASA's Deep Space Network, the system of radio telescopes that communicates with distant space probes.
But the network is also needed to talk to NASA's many other space probes, so 16 months will pass before scientists can get their hands on all of the data from this week's flyby. This week, the New Horizons team will retrieve a few choice images and snippets of what they think will be the science highlights. The New Horizons team and the Applied Physics Laboratory have left no stone unturned in the effort to keep Plutophiles entertained and engaged while they await New Horizons' daredevil pass by Pluto Tuesday morning.
Among them was Barbara Mikulski, the retiring senator from Maryland who has been a bulldog over the years fighting for funding for NASA and space exploration.

Midway through the afternoon S. Alan Stern, the mission's principal investigator, took the stage. He pointed out that with the discovery of the Kuiper Belt, Pluto is not a misfit anymore. He chided his fellow astronomers for not wanting to extend the number of planets when Kuiper belt objects started piling up. But as Dr. Stern pointed out, the small things are winning. God bless my space agency. As New Horizons flies by Pluto the room will be filled with a select group of scientists and engineers, who contributed to its nine-and-a-half year journey in some way.

Two people obtained an invitation from S. Alan Stern, the mission's principal investigator, in recognition of a scientific contribution of another kind: a song. Stern had been less enamored of previous musical efforts. Five months ago, Christine Lavin, a singer, sent another song to Mr. This focused more on the debate about whether Pluto is a planet.
Stern, who firmly believes Pluto is a planet, told her. Lavin reached out to Mr. Werth, another folk singer, who she thought could create something more to Dr. Stern's liking. Scott J. A new paper by Dr. Kenyon and Benjamin C. Bromley of the University of Utah pinpoints places where moons — and even rings, like a miniature version of Saturn's — could be lurking around Pluto.
Pluto has five known moons, more than Mercury, Venus, Earth and Mars put together. The biggest was discovered from a telescope on Earth in ; the four smaller ones were spotted in the last decade by the Hubble Space Telescope, which is in orbit around Earth. The team working on New Horizons, which will fly by Pluto on Tuesday, has assiduously searched for additional moons and so far has found none.
That is both a relief — moons and smaller debris are potential dangers to a spacecraft speeding at 31, miles per hour — and a surprise. Alan Stern, the principal investigator for New Horizons. Stern said, "like it is to me and others here, that we were just barely able to see the smallest satellite from Earth and there was nothing else? The telescopic camera on New Horizons can already spot objects as small as a mile across, and it will be even more eagle-eyed as it approaches.
Kenyon, who is not on the New Horizons team, has a second prediction about Pluto: "It will have a lot of craters. That is not going out on a limb. Stuff runs into everything in the solar system, and Pluto is unlikely to have any geological processes that could erase impact craters like a shaken Etch-a-Sketch. That is a lot more precise than earlier estimates of the diameter, which had ranged from 1, miles to 1, miles. Alan Stern, the mission's principal investigator, referring to the ring of icy debris beyond Neptune's orbit. Pluto is now known to be bigger than Eris, the icy world discovered farther out in the Kuiper belt in Eris was so bright that it seemed certain to be bigger than Pluto, and initial measurements seemed to confirm that.
But later, astronomers were able to make a more precise measurement when a star passed behind Eris. Eris was just 1, miles in diameter. Similar measurements had been made for Pluto, but the uncertainties were greater, because Pluto has an atmosphere that bends starlight. The larger diameter, in turn, means that Pluto is less dense than had been thought, and that in turn means a greater proportion of ice and less rock in its composition.
And while Pluto is now the biggest object in the Kuiper belt, Eris remains the heavyweight: It is 27 percent more massive than Pluto. It is believed to be an inherited characteristic, but may not follow a simple dominant-recessive pattern. It is not so much that the second toe is too long, but that the first metatarsal bone, which connects the big toe to the main part of the foot, is too short.
The condition can shift too much the weight to the second metatarsal, causing pain, callus formation and musculoskeletal problems. Surgical correction is sometimes used, but proper foot support is the treatment of first resort. This is my dream job. Lisa Amati, who was recently appointed New York's state paleontologist. She's answering reader questions. And mission managers are confident that they have aimed precisely enough that the spacecraft, traveling 31, miles an hour, will pass through a rectangle just 60 miles by 90 miles at its closest approach to Pluto.
In terms of accuracy, that's like driving from New York to San Francisco and ending up within about five inches of the parking spot you had selected before setting out. A computer program calculated the necessary trajectory, including a swing by Jupiter to pick up velocity.
That process is essentially unchanged from decades ago, when the Pioneer and Voyager probes similarly navigated to the outer solar system. Nonetheless, the details matter. The calculations have to factor in the gravitational tug of the sun and the planets. The tiny thrusters that spin New Horizons around also knock it off course slightly. Even the heat from the chunk of plutonium that acts as the spacecraft's battery produces a smidgen of thrust, and so does the small pressure of sunlight hitting the spacecraft.
All must be taken into account. Two teams of navigators do the calculations independently and then compare and reconcile their answers. That avoids mistakes like the one in when a mix-up between metric and imperial units pushed NASA's Mars Climate Orbiter slightly off course. It dipped too far into the atmosphere as it was entering orbit and was torn apart. The calculations are not perfect, so New Horizons has also fired its thrusters nine times during the nine and a half years for small course corrections, most recently two weeks ago. For the 11 million miles since then, New Horizons has been coasting, aimed at the middle of that bymile rectangle.
An earlier version of this post misstated the accuracy with which a driver could get a car from New York to a particular parking space in San Francisco, if it were as accurate as the New Horizons flight calculations. It is within about five inches, not five feet. The scientists working on NASA's New Horizons mission had called them "brass knuckles" — a series of four dark spots on the surface of Pluto, each about the size of Missouri, about miles wide.
As New Horizons speeds closer, the picture gets clearer. From 2. But this is probably the last good look at these particular spots, which are near the dwarf planet's equator. In the photograph, they are seen at the bottom in the photograph, because Pluto's axis of rotation is tipped over, with the north pole facing the sun and the approaching spacecraft.
From this perspective, essentially looking down at a spinning top, the north pole is in the brighter region in the upper center part of the picture. Pluto rotates every 6. But that just means there will be new surprises as more of the landscape comes into view. Read more about Pluto and the New Horizons mission and hear from those who made it happen in this New York Times documentary. The theory of evolution and a schoolteacher named John T.
Scopes went before a jury in the small town of Dayton, Tenn. The trial actually began as a public relations stunt. In , the American Civil Liberties Union took out an ad in a Chattanooga newspaper seeking a test case to challenge the Butler Act, a Tennessee law that forbade the teaching of any account of creation that differed from biblical tellings.
Residents of Dayton saw the ad and believed that finding someone to test the law would bring attention to their town. Scopes, who had strong convictions around freedom of discussion in the classroom, agreed to challenge the law. Many elements of the trial had a carnival-like atmosphere, including the appearance in Dayton of out-of-towners with chimpanzees and a 3-and-a-half foot man who was called a "missing link.
Early accounts of Mr. Scopes referred to him as "professor," but in reality he was a couple of years out of college and hired in Dayton to coach athletics in addition to teaching, and was not a specialist in biology. Scopes presented himself as a Christian who believed that the theory of evolution squared with his faith. The trial did little to settle any scientific or theological questions.
The Scopes defense, led by Clarence Darrow , had a group of scientists on hand. But the judge ruled a week into the trial that their testimony was not needed because the question before the court was only whether Mr. Scopes had given his students a lesson on evolution, a fact he did not contest, not whether evolution was true.
But the trial offered a major public forum for the clash of science and religion. Or as Mr. Darrow put it , the trial was, "the first of this sort since we stopped trying people in America for witchcraft. Scopes, who died in , outlived the law he was convicted of violating. It was overturned in But the fight about the teaching of evolution and creationism in American schools persists.
An earlier version of this post misstated the year in which the Butler Act, a law forbidding the teaching of evolution, was passed in Tennessee. It was , not It is moving that fast. And on the morning of Tuesday, July 14, after nine and a half years hurtling forward at 31, miles per hour, it will pass Pluto. If you want to understand how the mission came to be and why it is such a big deal, we recommend sitting down with a cup of tea or glass of wine and watching this documentary. Here are a few quotes you may want to keep in reserve for conversation lulls at future summer barbecues :.
It would be like colliding with a brick at 60 miles an hour. And so we want everything to go flawlessly, right, the first time. The only time. The New Horizon spacecraft passed the moon in nine hours. Karen S. Rommelfanger, director of the Neuroethics Program at the Center for Ethics at Emory University on studies of brain networking involving monkeys and rats. This is the week of their sting-filled arrival. Blooms of thousands of species of jellyfish not just box jellies occur all over the world throughout the year. But the swarms of the Alatina alata, as it's known, are distinctive, said Dr.
Angel Yanagihara , a biochemist and box jelly researcher at The University of Hawaii at Manoa, because of how predictably their reproductive patterns follow the moon. Every month, at the same time, hundreds to thousands fill the coastal waters. A swarm or bloom, as it is also called, lasts about three days, as they spawn. The Waikiki Aquarium maintains a jellyfish bloom calendar for planning purposes. Box jellies, like coral, anemone and other jellyfish, are armed with cells that can be injected like venom harpoons into prey or predators.
Although it is uncommon, the stings of Alatina alata sometimes accompany severe symptoms that can send their victims to the hospital. Barring special creams, the best way to treat a sting, Dr. Yanagihara said, is to spray it with vinegar and then immerse it in hot water. But, Dr. Yanagihara said these box jellies are like hot peppers — even small ones can pack a big punch. If you capture an image of a jellyfish bloom where you live, tag it nytscience on Instagram.

During a visit to Boston's Museum of Science, year-old Joseph Rosenfeld uncovered what seemed to be an error in a math equation that had stood unquestioned on the wall for 34 years. The exhibit aimed to explain a mathematical formula known as the "golden ratio," which describes a specific relationship between a line, shape or object and its parts.
The museum explained the formula in terms of the short side BC of a line being divided by the long side AB of the line:. Rosenfeld said that the museum had mixed up its positive signs with negative signs. The museum conceded to Mr. Rosenfeld's keen eye and then the Internet went wild — only for the museum to reverse course, asserting that the exhibit was correct. The more common way of seeing the golden ratio portrayed is in terms of the long side AB being divided by the short side BC :.
Still, Dr. Livio said he was happy to see that the 10th grader had seen the ratio before and that he questioned what he thought was a mistake. Opportunity's camera has captured footage from every mile crossed over the 11 year journey. Now NASA has released an 8-minute time-lapse of the rover's entire expedition. We then condensed the mile journey further into just 26 seconds.
Next Stop: the western end of the appropriately named Marathon Valley. We've been tracking the Curiosity rover's journey across Mars as well. See photos and take a hike across Gale Crater. David M. Hillis, an evolutionary biologist at the University of Texas at Austin, from a Science Times interview. The illustrations here were created from scans of six people, who were all 5 feet 9 inches tall and pounds. This means that though their bodies look very different, they all have exactly the same body mass index, or B. At By the most common definition people with a B.
How is it possible that the same B. The simple explanation is that muscle and bone are denser than fat and some people carry more or less weight in their torso or legs. This is a crucial shortcoming as some research now suggests that body fat percentage and body composition are more important indicators of health than weight alone. That puts the emphasis on exercises that don't just burn calories, but also build muscle. This also means that, to get a summer "beach body," a strict weight loss goal might not be the right path.
But it is nothing compared with what you will see in a week, when NASA's New Horizons spacecraft buzzes just 7, miles above Pluto's surface. This visit will bring the dwarf planet into focus for the first time, illuminating mysterious dark regions on its surface and possibly erupting ice volcanoes. By photographing a surface from multiple vantage points, scientists will be able to construct a topographic map of the former ninth planet. Those working on this mission have been waiting many years for a close-up. The fly-by, at a. Eastern time on July 14, comes 14 years after the initial proposal and nine and a half years after New Horizons left Earth.
The spacecraft will fly through the Pluto system at about 10 miles per second or around 31, miles per hour. You can read more about why this mission is so exceptional in this week's Science Times cover story and hear from those who made it happen in this New York Times documentary. Richard de Dear, director of the Indoor Environmental Quality Laboratory at the University of Sydney, on one reason why your office is so air conditioned.
Solar Impulse 2, an experimental plane flown by pilots who aim to complete the first round-the-world solar-powered flight, landed in Hawaii on Friday after five days aloft. The pilots are Andre Borschberg and Bertrand Piccard, Swiss explorers who hope to draw attention to the capabilities of clean technologies and renewable energy. Borschberg was at the helm for this leg of the flight — more than 4, miles from Nagoya, Japan, to Oahu — which set a record as the world's longest solar-powered flight by both time and distance, and as the longest solo flight by time.
The aircraft, which has 17, solar cells and a wingspan of feet, began the mission on March 9 in Abu Dhabi. All told, the trip is expected to cover almost 22, miles. Grab at the eyes and gills, which are very sensitive. Punching the shark in the nose may help but is difficult to do in the water. Andrew P. New York Times food writers have advocated cooking directly on hot coals this Fourth of July, but the truly adventurous may want to consider another approach: lava-grilled steak. The Syracuse University professors Bob Wysocki and Jeff Karson, the leaders of this minimalist technique, say the key is to start with thin-cut steaks, the more marbled the better.
You then find the nearest retrofitted bronze furnace. When not cooking dinner with it, Mr. Wysocki, an artist, and Mr. Karson, a geologist, create lava for scientific research and sculptures. Flames and smoke will dance around the steaks as they sizzle, but the professors say the steaks are safe to eat because their basic basaltic ingredients don't release any volatile compounds when melted.
You might take inspiration from NPR's Adam Cole, who made a delightful video about the Syracuse caldron, and follow with a dessert of lava-toasted marshmallow. Living things are often roundish, sometimes sharp and pointy, but rarely square. But the seahorse, in both its geometry and other traits, is an exception.
They have a hard, bony external skeleton. The male endures pregnancy and birth contractions may last 12 hours , and their prehensile tail, which they use to hang on to things, is square. Michael M. Porter, at Clemson University, is a mechanical engineer, which made him wonder about the mechanics of the tail. Why square? He and some other scientists made 3-D printed models of the tail — no seahorses were tormented during this research — and found, as he reported in Science , that the square tail grips better, is more sturdy and bounces back into shape more quickly than round tails do from torsion, meaning being twisted around and generally messed with.
Probably, he said, the square structure appeared first in something like a pipefish, and then turned out to be useful in other ways.

What is the X and from what depth did this apparatus just emerge? For the past week, Jupiter and Venus have been drawing closer in their race around the sun. On Tuesday night they nearly kissed.

John Barnes, who received an energy audit from students at Maine's College of the Atlantic. Silent for 33 years, Wolf volcano in the Galapagos Islands released an explosive howl a few weeks ago, spewing fire and ash nearly 50, feet high, according to NASA. On Tuesday the agency released images captured by its Terra satellite on June 11 that show lava leaking across Isabela Island and into the sea.
To better display the aftermath of the eruption, NASA digitally altered the image so that the volcanic spew looks like black rivers flooding red areas, which represent the island's grass and other plants. By now you may have heard a joke or two about what someone wants to do with the extra time tonight. But while the added time may not seem like much to a person — who could squander a second with almost three blinks of an eye — for a fast-paced creature like the hummingbird , that spare moment could mean as many as 80 extra wing flaps as it zooms from flower to flower drinking nectar.
Why choose June 30 for this drive for investing in planetary defenses against asteroid strikes? On June 30, , a hydrogen-bomb-level explosion occurred over a remote section of Siberia, demolishing tens of millions of trees over hundreds of square miles. Scientists continue to debate whether the extraterrestrial object that exploded over Tunguska was an asteroid or a comet fragment.
Previous — now discarded — theories include a proposal in that a black hole no larger than a grain of dust might have caused the Tunguska blast and an explanation published in that antimatter was the source. A naturally occurring atomic blast and a spaceship were also blamed. In contrast, a article in The Times, the first time it was mentioned here, offered a much more down-to-earth description of the explosion. Pseudo-holidays aside, protecting the planet from objects from outer space is an actual pursuit, involving policy makers and scientists. Bruce H.
