    PARIS (AFP) - Genetic material from outer space found in a meteorite in Australia may well have played a key role in the origin of life on Earth, according to a study to be published Sunday. European and US scientists have proved for the first time that two bits of genetic coding, called nucleobases, contained in the meteor fragment, are truly extraterrestrial. Previous studies had suggested that the space rocks, which hit Earth some 40 years ago, might have been contaminated upon impact. Both of the molecules identified, uracil and xanthine, "are present in our DNA and RNA," said lead...

    A cuneiform clay tablet that has puzzled scholars for over 150 years has been translated for the first time. The tablet is now known to be a contemporary Sumerian observation of an asteroid impact at Köfels, Austria and is published in a new book, 'A Sumerian Observation of the Köfels' Impact Event.' The giant landslide centred at Köfels in Austria is 500m thick and five kilometres in diameter and has long been a mystery since geologists first looked at it in the 19th century. The conclusion drawn by research in the middle 20th century was that it must be...

    How The Peruvian Meteorite Made It To EarthThe Carancas Fireball. Planetary geologists had thought that stony meteorites would be destroyed when they passed through Earth's atmosphere. This one struck ground near Carancas, Peru, at about 15,000 miles per hour. Brown University geologists have advanced a new theory that would upend current thinking about stony meteorites. (Credit: Peter Schultz, Brown University) ScienceDaily (Mar. 12, 2008) — It made news around the world: On Sept. 15, 2007, an object hurtled through the sky and crashed into the Peruvian countryside. Scientists dispatched to the site near the village of Carancas found a gaping...

    Astronomers Capture Rare Video Of Meteor Falling To Earth; Hunt For Meteorite ScienceDaily (Mar. 8, 2008) — Astronomers from The University of Western Ontario in London, Ontario, have captured rare video of a meteor falling to Earth. The Physics and Astronomy Department at Western has a network of all-sky cameras in Southern Ontario that scan the sky monitoring for meteors. Associate Professor Peter Brown, who specializes in the study of meteors and meteorites, says that Wednesday evening (March 5) at 10:59 p.m. EST these cameras captured video of a large fireball and the department has also received a number of...

    SPOKANE, Wash. — An apparent meteor streaked through the sky over the Pacific Northwest early Tuesday, drawing reports of bright lights and sonic booms in parts of Washington, Oregon and Idaho. Although a witness reported seeing the object strike the Earth in a remote part of Adams County, in southeast Washington, it had not been found. "I'm convinced it was a meteor," said Geoff Chester, spokesman for the U.S. Naval Observatory in Washington, D.C. "It was a classic description of a fireball." Chester speculated the meteor was the size of a big suitcase and had been orbiting the sun for...

    Well water of the tiny Canadian town of Gypsumville, Manitoba (population 65) has been poisoned by an extraterrestrial. The invader: A meteorite which struck down almost a quarter-billion years ago, creating the 25-mile-wide (40-kilometer) Lake Martin impact crater. The ancient impact shattered the granitic ground so that extraordinary amounts of fluoride now taint the well water. Slightly higher than recommended amounts of fluoride can cause mottled teeth, while even higher concentrations can lead to neurological problems and softened bones. This is could be the first time a meteor impact has been tied to a modern health threat, say the geologists...

    Meteors' mysterious origin traced to 1490 event 15:50 07 January 2008 NewScientist.com news service Stephen Battersby Last week's Quadrantid meteor shower was probably debris from a deep-space explosion that went off in the late 15th century, new observations reveal. The meteors, which return every January, were observed more closely than ever before when a group of 14 astronomers tracked them for nine hours on a flight from California, US, to the North Pole. They found that the shower peaked at around 0200 GMT on Friday, matching a prediction made by Peter Jenniskens of NASA. He based his prediction on the...

    Airborne astronomers to track intense meteor shower 16:59 03 January 2008 NewScientist.com news service Stephen Battersby The most intense meteor shower of the year hits Earth tonight. If the skies are clear and you live at high northern latitudes, then you could see dozens of Quadrantid meteors streaking over the pole. Or you might spot a plane full of astronomers racing northward, trying to find out how this unusual meteor shower was created, and whether it is the shrapnel of a celestial explosion witnessed in the 15th century. Like other meteor showers, the Quadrantids appear when Earth moves through an...

    Earth & Sky ^ | 17 Nov 2007 | Deborah Byrd, Joel Block,
    Friday, November 16, 2007 According to predictions, the famous Leonid meteor shower will peak this weekend. The best viewing is predicted to be during the wee hours before dawn on Sunday, when you might see as many as 10 to 15 meteors per hour. But meteor showers are notorious for defying predictions, so don’t discount Saturday and Monday mornings. And don’t be too surprised if the Leonids surpass or fall shy of the predictions. Even though the first quarter moon will light the evening sky, moonlight shouldn’t bother this year’s Leonid meteor display. As a general rule, the fast-flying Leonid...

    A flaming object over Minnesota skies this afternoon may have been a meteor. Shortly after 2 p.m., people across the Twin Cities reported seeing a "metallic" object or "flaming ball" falling from the sky. Broadcasters and emergency dispatchers got hundreds of calls from people who saw the object traveling from the northeast to the southwest. The FAA received no reports of anything falling from any airplanes in the area, leading to speculation that it was a meteor that burned up in the atmosphere, since no crash site has been identified. Residents of Lyon County in far southwestern Minnesota reported a...

    A two-topic post. First, you may have heard "Andromeda Strain" type reports of a meteor impact in Peru that reportedly caused illness in 300 people or so. The reports were unclear; some doubted there even was a meteor at all. Well, there was. The linked article in the header is about it; apparently the meteor (meteorite when it hit, of course) hit where the water table was shallow, causing some steaming. Analysis has confirmed the extraterrestrial origin, and maybe about 30 people were bothered by it. This is a summary of the article; read the whole thing for the more...

    An object that struck the high plains of Peru on Saturday, causing a mysterious illness among local residents, was a rare kind of meteorite, scientists announced today. A team of Peruvian researchers confirmed the origins of the object, which crashed near Lake Titicaca, after taking samples to a lab in the capital city of Lima (see Peru map). Nearby residents who visited the impact crater complained of headaches and nausea, spurring speculation that the explosion was a subterranean geyser eruption or a release of noxious gas from decayed matter underground. But the illness was the result of inhaling arsenic fumes,...

    TOMS RIVER (1010 WINS) -- A fiery streak across the sky got the attention of the Coast Guard Saturday night, after the reported fireball crashed into the waters off the Jersey Shore. Concerned calls started coming in from South Carolina to Long Island about 9 p.m. Coast Guard boats were searching near the site of the reported impact, off Normandy Beach in Toms River, about 10 miles off shore. No debris has been found in the water. The Toms River Fire Department says it also got some calls and there were at least 20 people on the beach with the...
  • 2000-Year-Old Meteors to Rain Down on August 31, 2007

    The meteors that are about to rain down in the early morning of September 1 date from around 4 A.D., the latest calculations show. It is not often that we can tell when a shooting star was first released from a comet into space, to travel as a meteoroid in an orbit around the Sun, and finally collide with Earth's atmosphere to shine as a meteor for our enjoyment. Most meteors that sporadically flash across the sky on a dark moonless night date from anonymous times. Only in recent years have we learned to trace young meteor showers, just a...

    LOS ANGELES – Summer's annual meteor shower promises to put on a dazzling show when it peaks this weekend – provided you're far from city lights. With no moon in sight to interfere with the Perseid meteor shower, skygazers can expect to spot streaking fireballs late Sunday into dawn Monday regardless of time zone. Astronomers estimate as many as 60 meteors per hour could flit across the sky at the shower's peak. This year's sky show comes with an added bonus: Mars will be visible as a bright red dot in the northeastern sky. “We have front-row seats this year,”...

    Rare meteor shower to shed light on dangerous comets 17:07 08 August 2007 NewScientist.com news service Stephen Battersby A rare meteor shower predicted to hit Earth on 1 September should give astronomers only their second chance to study an ancient comet's crust. It could also help them develop a warning system against an otherwise insidious threat – a comet aimed at Earth from the dark fringes of the solar system. September's shower, called the alpha Aurigids, has only been seen three times before, in 1935, 1986 and 1994. The reason for this elusiveness is the shower's unusual origin. Most meteor...

    Bits of Halley's Comet will streak into the Earth's atmosphere before dawn on Sunday during the peak of the eta Aquarid meteor shower. Although moonlight will make all but the brightest meteors impossible to see, those that are visible may be quite spectacular due to the geometry of the shower. Halley's Comet last swung by the Earth in 1986 and now lies in the outer solar system. But every time it passes near the Sun on its 76-year orbit, the nucleus of the icy object sheds about 6 metres of material, which spreads out along the comet's orbit. Twice a...

    Sorry for the shameless vanity, but I was just outside in the back yard in Northern Georgia, and an incredibly bright light illuminated the dark yard like an arc lamp. I looked up and saw a meteor streaking overhead, white hot, which then broke up into orange, glowing fragments. This happened at 10:21PM EST. I apologize for posting something random like this, but it was astonishing. Perhaps it was a piece of space junk that reentered the atmosphere tonight. Did anyone else see this? It was truly spectacular.

Rather than Hollywood's preferred option, engineers are trying to develop unmanned rockets that can land on space rocks and use the asteroids' own material to propel them into a safer orbit. The plan will be detailed at a conference, sponsored by Nasa next month, at which its scientists will reveal their -estimate that 100,000 asteroids orbiting near...
