    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.

    In breaking news, Anthony Wesley reports another impact on Jupiter, this morning. In his words: ".. at approximately 20:30utc this morning I recorded a large fireball on Jupiter, it lasted a couple of seconds and was very bright.This was a large fireball, but it doesn't seem to have left any mark, probably all gone in the upper atmosphere before it reached the clouds."His preliminary image (a raw frame from the video) is shown below. The fireball can be seen in the upper left of frame. A video and more details will follow soon.Stay tuned to IceInSpace for more, and for...

    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...

    WASHINGTON – Scientists have lots of ice in an unexpected place in our solar system: an asteroid between Mars and Jupiter. The discovery of significant asteroid ice has several consequences. It could help explain how Earth first got its water. It makes asteroids more attractive to explore. And it muddies the definition between comets and asteroids.

    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...

    Asteroid passes just 8,700miles from Earth - with only 15 hours warning Its orbit brought it 30 times nearer than the Moon Don't panic! Although the asteroid passed within 9,000 miles of Earth it measured just 23ft across and wouldn't have dented the surface (artist's illustration) site where meteorite hit the tumbling rock was only 23ft across. Similar sized objects pass by this close to Earth about twice a year and impact on the planet about once every five years. Astronomers believe the object, called 2009 VA, would have almost completely burned up while entering Earth's atmosphere, causing a brilliant...

    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. Similar sized objects pass by this close to Earth about twice a year and impact on the planet...

    INDONESIAN ASTEROID: Picture this: A 10-meter wide asteroid hits Earth and explodes in the atmosphere with the energy of a small atomic bomb. Frightened by thunderous sounds and shaking walls, people rush out of their homes, thinking that an earthquake is in progress. All they see is a twisting trail of debris in the mid-day sky: This really happened on Oct. 8th around 11 am local time in the coastal town of Bone, Indonesia. The Earth-shaking blast received remarkably little coverage in Western press, but meteor scientists have given it their full attention. "The explosion triggered infrasound sensors of the...
  • NASA downgrades threat of large asteroid (WHEW!!! 2036 strike even more less likely)

    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.

    Daily Galaxy ^ | 9/26/09 | Stephen Hawking
    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,...

    Congress assigned the space agency four years ago to watch 90 per cent of potentially deadly rocks hurtling through space by 2020 but never gave it the money to build the necessary telescopes, according to a report by the National Academy of Sciences. The agency estimates that about 20,000 asteroids and comets in Earth's solar system bigger than 460 feet in diameter are potential threats to the planet. Rocks between 460 feet and 3,280 feet in diameter can devastate an entire region Lindley Johnson, NASA's manager of the near-Earth objects program, said. So far, scientists know the whereabouts of about...

    Jupiter’s new black spot The black spot is at the top of this image. I just saw on Twitter (hard to believe I ever thought Twitter was useless) that Jupiter is sporting a new black spot near its south pole. You can see it in the picture here (click to go to the source and embiggen). People on Twitter (and on that site linked above) are speculating that this is the result of a large impact on Jupiter, similar to what happened in 1994 when comet Shoemaker-Levy 9 slammed into the big planet. But I think that’s premature; weather changes...

    Asteroid hunters have good news and a challenge for the rest of us. After an extensive search for asteroids a kilometer or more across, engineer Steve Chesley says that "we can now say with confidence that no asteroids large enough to cause such a global calamity [as killing off the dinosaurs] are headed our way." But if one of them or even a smaller, city-destroying rock were detected on a collision course, would the world community be prepared to handle it? A conference of legal experts that discussed this question at the University of Nebraska in Lincoln last month answered...

    Time CNN ^ | Monday, Apr. 27, 2009 | Jeffrey Kluger
    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.

    Just before dawn on Oct. 7, 2008, an SUV-sized asteroid entered Earth's atmosphere and exploded harmlessly over the Nubian Desert of northern Sudan. Scientists expected the asteroid, called 2008 TC3, had blown to dust in the resulting high-altitude fireball. What happened next excited the scientific community. Peter Jenniskens, a meteor astronomer with the SETI Institute in Mountain View, Calif., who works at NASA's Ames Research Center in Moffett Field, Calif., joined Muawia Shaddad of the University of Khartoum in Sudan to search for possible extraterrestrial remnants from the asteroid. A paper, featured as the cover story in the March 26...
