    Gizmodo ^ | November 02, 2015 | Attila Nagy [Photo: Peter Komka/MTI]
    Hungarian photographer Péter Komka wanted to capture the Halloween asteroid that looked like a skull, as it made its closest approach to Earth. What he got instead was a striking image of a meteor streaking across the sky. Komka set up his camera gear on an equatorial mounted tripod near the medieval castle of Salgó, and took several long exposure shot of the night sky, hoping to get some good enough image of the 2015 TB145 asteroid. Sadly the spooky space rock was too faint and did not appear in his photos. But what he finally captured in one photo...

    Elizabeth Palermo September 15, 2015An artist's depiction of the dual meteor strike. (Don Dixon/Erik Sturkell/University of Gothenburg) It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago. Researchers from the University of Gothenburg uncovered two craters in the county of Jämtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor...

    A big asteroid sailed past Earth last month, and astronomers haven't yet totally excluded the possibility that it'll hit us when it comes around in 2032. If the past is any guide, we won't have to worry about asteroid 2013 TV135 — but it's a reminder that we'll have to fend off a killer space rock one of these days. Ukrainian astronomers discovered 2013 TV135 just 10 days ago, well after the asteroid had its close encounter with Earth on Sept. 16. Actually, it wasn't all that close: The distance was 4.2 million miles (6.7 million kilometers), or about 17...
  • Jupiter Has Taken a Massive Meteor Hit (So Earth Didn’t Have To)

    On Monday, Jupiter took a massive hit from a meteor, which was spotted by amateur astronomers based in the US—and if previous evidence is anything to go by, it could have saved Earth from a massive collision in the process. Dan Peterson of Racine, Wisconsin, was gazing at Jupiter on Monday when he saw a bright, white flash on the surface of the planet. When he posted his observation online, another astrophotographer, George Hall, discovered he'd unknowingly captured the massive explosion on video. Turns out it was probably a meteor striking the surface of the planet—and you can watch the...

In a paper published Thursday in the Astrophysical Journal Letters, a group of professional and amateur astronomers announced that Jupiter is getting hit surprisingly often by small asteroids, lighting up the giant planet's atmosphere with frequent fireballs. "Jupiter is a big gravitational vacuum cleaner," said co-author and JPL astronomer Glenn Orton. "It is clear now that relatively small objects left over from the formation of the solar system 4.5 billion years ago still hit Jupiter frequently." The impacts are...

    Without warning, a mystery object struck Jupiter on July 19, 2009, leaving a dark bruise the size of the Pacific Ocean. The spot first caught the eye of an amateur astronomer in Australia, and soon, observatories around the world, including NASA’s Hubble Space Telescope, were zeroing in on the unexpected blemish. Astronomers had witnessed this kind of cosmic event before. Similar scars had been left behind during the course of a week in July 1994, when more than 20 pieces of Comet P/Shoemaker-Levy 9 (SL9) plunged into Jupiter’s atmosphere. The 2009 impact occurred during the same week, 15 years later....

    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...

    National Geographic ^ | 8/24/10 | Andrew Fazekas
    Amateur sightings prompt call for a network of backyard astronomers.On August 20, for the third time in about a year, amateur astronomers spotted a fireball above Jupiter's atmosphere. The discovery suggests the planet gets walloped more often than previously thought, say astronomers, some of whom are calling for a global "volunteer army" of backyard Jupiter watchers. The recent flash follows on the heels of July 2009 and June 2010 fireballs over the gas giant planet. (See "Bright Fireball Slams Into Jupiter" [June 2010] and "Jupiter Impact Creates Huge New Spot" [July 2009].) Astronomers speculate that the August 20 flash was...

    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,...

    Crater patterns on Vesta and Ceres could help pinpoint when Jupiter began to form during the evolution of the early Solar System. A study modelling the cratering history of the largest two objects in the asteroid belt, which are believed to be among the oldest in the Solar System, indicates that the type and distribution of craters would show marked changes at different stages of Jupiter’s development. Results will be presented by Dr Diego Turrini at the European Planetary Science Congress in Potsdam, Germany, on Monday 14 September. The study, carried out by scientists at the Italian National Institute for...

    Hubble has trained its new camera on the atmospheric disturbance on Jupiter believed to have been caused by a comet or asteroid impact. The telescope used the Wide Field Camera 3 fitted on the recent shuttle servicing mission to capture ultra-sharp visible-light images of the scar. The dark spot near the gas giant's southern pole was noticed first by an amateur Australian astronomer.

    PASADENA, California — A large comet or asteroid has slammed into Jupiter, creating an impact site the size of Earth, pictures by an Australian amateur astronomer show. NASA's Jet Propulsion Laboratory confirmed the discovery using its large infrared telescope at the summit of Mauna Kea in Hawaii, said computer programer Anthony Wesley, 44, who discovered the impact zone while stargazing at home. News of Wesley's find on a backyard 14.5-inch reflecting telescope has stunned the astronomy world, with scientists saying the impact will last only days more. Wesley said it took him 30 minutes to realize a dark spot rotating...

    Without Jupiter acting as a "cosmic vacuum cleaner" sucking up these dangerous objects, there would be so many catastrophic impacts that life probably wouldn't have evolved on the Earth and we wouldn't be here today... "This vacuum cleaner idea goes back to when the long-period comets coming in from the Oort Cloud were viewed as being the only significant impact risk," says Horner. "In the 1950s there were only one or two near-Earth asteroids known, so they were viewed as oddities." ...Since the 1950s, scientists have discovered more objects in the solar system, and they say many of them could...

In fact, Earth would suffer fewer impacts without the influence of Jupiter's gravity, a new study says. It could have implications for determining which solar systems are most hospitable to life. A 1994 study showed that replacing Jupiter with a much smaller planet like Uranus or Neptune would lead to 1000 times...

    Scientists Have Underestimated The Likelihood Of City-Killing Asteroids Hitting Earth Reuters Irene Klotz, Reuters Apr. 28, 2014, 2:59 PM The chance of a city-killing asteroid striking Earth is higher than scientists previously believed, a non-profit group building an asteroid-hunting telescope said on Tuesday. A global network that listens for nuclear weapons detonations detected 26 asteroids that exploded in Earth's atmosphere from 2000 to 2013, data collected by the Comprehensive Nuclear Test Ban Treaty Organization shows. The explosions include the Feb. 15, 2013, impact over Chelyabinsk, Russia, which left more than 1,000 people injured by flying glass and debris. "There is...

    Mega-tsunami theory disputed February 03, 2008 SUPPOSED evidence Australia has been subject to prehistoric tsunamis up to 20m in height over the past 10,000 years could just be the result of Aboriginal occupation, a major conference is set to hear tomorrow. Archaeologists from the Australian National University say the theory about the mega-tsunamis, which has influenced the development of emergency service plans in Western Australia, is not supported by evidence. In 2003 Australian geological researchers suggested prehistoric tsunamis over the past 10,000 years were much larger than those recorded since European settlement, including findings of surges up to 20m in...

Easterbrook Dept. of Geology, Western Washington University.The Younger Dryas was a period of rapid cooling in the late Pleistocene 12,800 to 11,500 calendar years ago. It followed closely on the heels of a dramatically abrupt warming that brought the last Ice Age to a close (17,500 calendar years ago), lasted for about 1,300 years, then ended as abruptly as it started. The cause of these remarkably sudden climate changes has puzzled geologists and climatologists for decades and despite much effort to find...

Indeed, except for reflecting on the AD 837 apparition of Halley's Comet (when it should have been as bright as Venus and would have moved through 60 degrees of sky in one day as it passed just 0.03 AU from Earth - three times closer than Hyakutake in 1996), you may...
