    A group of astronomers from NASA, the Japan Aerospace Exploration Agency (JAXA) and other organizations had a front row seat to observe the Hayabusa spacecraft's fiery plunge into Earth's atmosphere. The team was aboard NASA's DC-8 airborne laboratory, packed with cameras and other imaging instruments, to capture the high-speed re-entry over an unpopulated area of central Australia on June 13, 2010. The Japanese spacecraft has been on a seven-year journey to return a sample of the asteroid Itokawa.

    SYDNEY (AFP) – A capsule that scientists hope will contain a little slice of outer space after a seven-year journey across the solar system was sitting in the Australian Outback on Monday waiting to be recovered. The pod, which was ejected from a Japanese space probe as it burned up in a spectacular meteor-like display over Australia, could hold the first piece of asteroid ever brought to Earth. The heat-resistant pod parachuted into the Woomera military zone after being ejected from Japan's Hayabusa spacecraft as it flamed back into the planet's atmosphere late Sunday. Australian National University scientist Trevor Ireland,...

    A Japanese spacecraft that visited an asteroid in 2005 is returning to Earth this weekend and should put on a brief, but spectacular, light show for fortuitously placed Australians late on Sunday. The Hayabusa probe was launched by the Japanese Aerospace Exploration Agency (JAXA) on May 9, 2003 and rendezvoused with the Itokawa asteroid on September 12, 2005. [Photos of Japan's asteroid mission.] Now it is set to land back on Earth, hopefully with asteroid bits in tow.

    Water ice has been found on the surface of a nearby asteroid for the first time – a discovery that could help explain how Earth got its oceans, scientists announced Wednesday. Two teams of researchers independently verified that the asteroid 24 Themis – a large rock hurtling through space in the asteroid belt between Mars and Jupiter – is coated in a layer of frost. They also found that the asteroid contains organic material, including some molecules that might be ingredients for life. But scientists have not found any evidence for life itself on this asteroid, or anywhere else in...

    Collisions between asteroids should be highly energetic affairs, with an average impact speed of close to 5 kilometers per second. We may be looking at the debris of a head-on collision between two asteroids in imagery provided by the Hubble Space Telescope. The object in question, originally thought to have been a comet, is P/2010 A2, discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) sky survey on January 6 of this year. The follow-up Hubble imagery dates from late January, and shows an unusual filamentary pattern near the nucleus.Image: HST picture of the comet-like object called P/2010 A2. The object...

    Although no one noticed at the time, the Earth was almost hit by an asteroid last Friday. The previously undiscovered asteroid came within 8,700miles of Earth but astronomers noticed it only 15 hours before it made its closest approach. To put it in perspective the Moon is a distance of 250,000miles, which is nearly 30 times further away from our planet. But before you head for the nuclear bunkers you will be relieved to learn the tumbling rock was only 23ft across.

    LOS ANGELES – Earth can breathe a sigh of relief. NASA on Wednesday downgraded the odds of an 885-foot asteroid striking the planet in 2036. Scientists initially believed there was a 1-in-45,000 chance that Apophis could hit the planet on April 13, 2036. But the threat was lowered to a 1-in-250,000 chance after researchers recalculated the asteroid's path. "It wasn't anything to worry about before. Now it's even less so," said Steve Chesley, an astronomer with the Near Earth Object Program at NASA's Jet Propulsion Laboratory.

    Stephen Hawking believes that one of the major factors in the possible scarcity of intelligent life in our galaxy is the high probability of an asteroid or comet colliding with inhabited planets. We have observed, Hawking points out in Life in the Universe, the collision of a comet, Schumacher-Levi, with Jupiter (below), which produced a series of enormous fireballs, plumes many thousands of kilometers high, hot "bubbles" of gas in the atmosphere, and large dark "scars" on the atmosphere which had lifetimes on the order of weeks. It is thought the collision of a rather smaller body with the Earth,...

    When a scientific principle is common knowledge even in grammar school, you know it has long since crossed the line from theory to established fact. That's the case with dinosaur extinction. Some 65 million years ago — as we've all come to know — an asteroid struck the earth, sending up a cloud that blocked the sun and cooled the planet. That, in turn, wiped out the dinosaurs and made way for the rise of mammals. The suddenness with which so many species vanished after that time always suggested a single cataclysmic event, and the 1978 discovery of a 112-mile,...

    April 13, 2009 -- Exactly 20 years from today, an asteroid about the size of a 25-story building will come closer to Earth than the networks of communications satellites orbiting the planet. The chance of an impact are extremely remote -- only about 1 in 45,000 -- but the asteroid, named Apophis, will be back. Analysis of the asteroid's orbit show it will return to Earth seven years later. Astronomers don't yet know if Apophis' second visit will be a rendezvous or a collision, as its orbit will be bent by Earth's gravity during the 2029 flyby.

In fact we have only a hazy understanding of how likely the asteroid Apophis is to strike Earth. What's more, budget cuts may shut down the telescope that could clarify the situation. Since Apophis was discovered in 2004, asteroid-watchers have known that it has a slim chance of hitting Earth in 2036. At 270 metres wide, it is too small to rival the object that wiped out the dinosaurs, but it could cause devastating tsunamis were it to...

    The true impact of an asteroid or comet crashing near the Chesapeake Bay 35 million years ago has been examined in detail for the first time. The analysis reveals the resilience of life in the aftermath of disaster. The impact crater, which is buried under 400 to 1,200 feet (120 to 365 meters) of sand, silt and clay, spans twice the length of Manhattan. The sprawling depression helped create what would eventually become Chesapeake Bay. About 10,000 years ago, ice sheets began to melt and once-dry river valleys filled with water.

    Could An Asteroid Hit Planet Earth, Again?Asteroid impact on early Earth. Some scientists believe that impacts such as this during the Late Heavy Bombardment period, 4 billion years ago, may have delivered primitive life to Earth. (Credit: Copyright Don Davis) ScienceDaily (Jan. 30, 2008) — Earth dodged a bullet today, when asteroid TU24 passed within 540,000 kilometers of our planet, which is just down the street on a galactic scale. Tomorrow, another asteroid – 2007 WD5 – will zip past Mars at a distance of only 26,000 kilometers away. Will we dodge the bullet the next time a near-Earth object...

    An asteroid at least 500 feet long will make a rare close pass by Earth next week, but there is no chance of an impact, scientists reported Thursday. The object, known as 2007 TU24, is expected to whiz by Earth on Tuesday with its closest approach at 334,000 miles, or about 1 1/2 times the distance of Earth to the moon. The nighttime encounter should be bright enough for medium-sized telescopes to get a glimpse, said Don Yeomans, manager of the Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory, which tracks potentially dangerous space rocks. However, next week's asteroid...

    PASADENA, Calif. - Scientists tracking an asteroid approaching Mars say that an impact with the Red Planet has become less likely. Refined estimates of the asteroid's orbit were made using new observations from a telescope at the Calar Alto Observatory in Spain, according to the Near-Earth Object Program at NASA's Jet Propulsion Laboratory. The impact probability fell to 2.5 percent, the NEO office said in Jan. 8 update posted on the NEO Web site. The miss distance was holding steady at about 30,000 kilometers, or 18,600 miles. The asteroid, dubbed 2007 WD5, was discovered in late November by the NASA-funded...

    Insect Attack May Have Finished Off Dinosaurs ScienceDaily (Jan. 4, 2008) — Asteroid impacts or massive volcanic flows might have occurred around the time dinosaurs became extinct, but a new argument is that the mightiest creatures the world has ever known may have been brought down by a tiny, much less dramatic force -- biting, disease-carrying insects.Tick found in Burmese amber. (Credit: Image courtesy of Oregon State University) An important contributor to the demise of the dinosaurs, experts say, could have been the rise and evolution of insects, especially the slow-but-overwhelming threat posed by new disease carriers. And the evidence...

    Additional position observations for asteroid 2007 WD5 taken on December 29 through January 2 have been used to improve the accuracy of the asteroid's orbit. As a result, the range of possible paths past Mars has narrowed by a factor of 3 and the most likely path has moved a little farther away from the planet, causing the Mars impact probability to decrease slightly to 3.6% (about one chance in 28). The new positional observations were made using the 2.4 meter telescope at New Mexico Tech's Magdalena Ridge Observatory and reported by astronomer Bill Ryan. It seems likely that as...

    Updated Dec. 28, 2007 -- Astronomers have identified asteroid 2007 WD 5 in archival imagery. With these new observations, scientists at NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif have refined their trajectory estimates for the asteroid. Based on this latest analysis, the odds for the asteroid impacting Mars on Jan. 30 are now 1-in-25 -- or about 4 percent.

    The chance of a football field-sized asteroid plowing into Mars next month has been increased to 4 percent, scientists said Friday after analyzing archival data. Though still a long shot, some researchers are hoping for a cosmic smash. "I think it'll be cool," said Don Yeomans, who heads the Near-Earth Object Program at NASA's Jet Propulsion Laboratory. "Usually when an asteroid is headed toward Earth, I'm not rooting for an impact." The space rock, known as the nondescript 2007 WD5, was discovered in late November by the NASA-funded Catalina Sky Survey in Arizona. Based on the latest information available, scientists...

    LOS ANGELES (Map, News) - Mars could be in for an asteroid hit. A newly discovered hunk of space rock has a 1 in 75 chance of slamming into the Red Planet on Jan. 30, scientists said Thursday. "These odds are extremely unusual. We frequently work with really long odds when we track ... threatening asteroids," said Steve Chesley, an astronomer with the Near Earth Object Program at NASA's Jet Propulsion Laboratory. The asteroid, known as 2007 WD5, was discovered in late November and is similar in size to the Tunguska object that hit remote central Siberia in 1908, unleashing...

    Astronauts, space buffs and an unimpressed public hunger for space exploration that's more dramatic, more heroic, more new. Something like, say, landing astronauts on a distant rock hurtling through space at 15 miles per second. That's exactly the kind of trip NASA has been studying. In fact, scientists at the space agency recently determined that a manned mission to a near-Earth asteroid would be possible using technology being developed today... This wouldn't be our first trip to an asteroid. We've been visiting them by proxy for years now, using unmanned space probes. In 2000 NASA's NEAR Shoemaker spacecraft arrived at...

    Source: SETI Institute Date: October 15, 2007 Long-lost, Dangerous Asteroid Is Found Again Science Daily — Echoing the re-discovery of America by the Spanish long after an earlier Viking reconnaissance, astronomers have learned that a recently observed asteroid - one that could potentially hit the Earth - was actually first observed nearly a half-century ago. Researchers at the Minor Planet Center of the Smithsonian Astrophysical Observatory in Cambridge, MA have confirmed work by SETI Institute astronomer Peter Jenniskens that the recently discovered asteroid 2007 RR9 is in fact the long-lost object 6344 P-L. So far, this object has not yet...

    A piece of outer space named for George Takei is in kind of a rough neighborhood for somebody who steers a starship: an asteroid belt. An asteroid between Mars and Jupiter has been renamed 7307 Takei in honor of the actor, best known for his role as Hikaru Sulu in the original "Star Trek" series and movies. "I am now a heavenly body," Takei, 70, said Tuesday, laughing. "I found out about it yesterday. ... I was blown away. It came out of the clear, blue sky — just like an asteroid." The celestial rock, discovered by two Japanese astronomers...
