This just in: reports of bright meteors and loud explosions have been coming from Russia, with the incredible video above showing what appears to be a meteor exploding in the atmosphere on the morning of Friday, Feb. 15.
According to Reuters the objects were seen in the skies over the Chelyabinsk and Sverdlovsk regions.
“Preliminary indications are that it was a meteorite rain,” an emergency official told RIA-Novosti. “We have information about a blast at 10,000-meter (32,800-foot) altitude. It is being verified.”
Chelyabinsk is 930 miles (1,500 km) east of Moscow, in Russia’s Ural Mountains.

A highly-respected scientist and astrobiologist with a prestigious record of accomplishment at NASA thinks he may have found evidence for extraterrestrial life. The Journal of Cosmology has taken the extraordinary step of inviting 100 scientists with specific expertise and 5,000 other members of the scientific community to review this paper by Dr. Richard Hoover.
The journal believes, correctly, that extraordinary claims require extraordinary proof. The paper will be published, along with reaction to it, March 7 through 10.

Scientists have announced that a large crater in Latvia that was claimed to be the results of a meteorite crashing to earth is, in fact, a hoax.
Experts had rushed to the site after reports that a meteorite had landed late on Sunday in Latvia's Mazsalaca region, near the Estonian border, and footage of the flames caused by its landing were widely shown after being posted on YouTube.
Unfortunately, it turned out it was just a hole someone had dug in the ground. The video was shot by a group of film-making students, which might be seen as something of a gievaway.Scientists have announced that a large crater in Latvia that was claimed to be the... more

The Opportunity rover has eyed an odd-shaped, dark rock, about 0.6 meters (2 feet) across on the surface of Mars, which may be a meteorite. The team spotted the rock called "Block Island," on July 18, 2009, in the opposite direction from which it was driving. The rover then backtracked some 250 meters (820 feet) to study it closer. Scientists will be testing the rock with the alpha particle X-ray spectrometer to get composition measurements and to confirm if indeed it is a meteorite.The Opportunity rover has eyed an odd-shaped, dark rock, about 0.6 meters (2 feet)... more

A 14-year old German boy was hit in the hand by a pea-sized meteorite that scared the bejeezus out of him and left a scar.
"When it hit me it knocked me flying and then was still going fast enough to bury itself into the road," Gerrit Blank said in a newspaper account. Astronomers have analyzed the object and conclude it was indeed a natural object from space, The Telegraph reports.
Most meteors vaporize in the atmosphere, creating "shooting stars," and never reach the ground. The few that do are typically made mostly of metals. Stony space rocks, even if they are big as a car, will usually break apart or explode as they crash through the atmosphere.
There are a handful of reports of homes and cars being struck by meteorites, and many cases of space rocks streaking to the surface and being found later.
But human strikes are rare. There are no known instances of humans being killed by space rocks.A 14-year old German boy was hit in the hand by a pea-sized meteorite that scared the... more

Popular Science does a rundown of the facts and concludes the story that appeared in the media last week about a kid being hit by a meteorite must be bogus.
"Could a pebble-sized meteor moving at that speed be dangerous? It could. Will it have a velocity sufficient to induce enough compressional heating to produce a "flash of light"? Not likely. Could it create an impact crater a foot in diameter? No, it couldn't. Busted!"

"Gerrit Blank, 14, was on his way to school when he saw "ball of light" heading straight towards him from the sky.
A red hot, pea-sized piece of rock then hit his hand before bouncing off and causing a foot wide crater in the ground.
The teenager survived the strike, the chances of which are just 1 in a million - but with a nasty three-inch long scar on his hand.
He said: "At first I just saw a large ball of light, and then I suddenly felt a pain in my hand.
"Then a split second after that there was an enormous bang like a crash of thunder."
"The noise that came after the flash of light was so loud that my ears were ringing for hours afterwards.
"When it hit me it knocked me flying and then was still going fast enough to bury itself into the road," he explained.
Scientists are now studying the pea-sized meteorite which crashed to Earth in Essen, Germany.
"I am really keen on science and my teachers discovered that the fragment is really magnetic," said Gerrit.
Chemical tests on the rock have proved it had fallen from space.
Ansgar Kortem, director of Germany's Walter Hohmann Observatory, said: "It's a real meteorite, therefore it is very valuable to collectors and scientists.
"Most don't actually make it to ground level because they evaporate in the atmosphere. Of those that do get through, about six out of every seven of them land in water," he added.
The only other known example of a human being surviving a meteor strike happened in Alabama, USA, in November 1954 when a grapefruit-sized fragment crashed through the roof of a house, bounced off furniture and landed on a sleeping woman.""Gerrit Blank, 14, was on his way to school when he saw "ball of light"... more

The lasting impression left by the Apollo missions is of a Moon that is gray, dusty, desolate and dead. But instruments left behind by Apollo astronauts recorded moonquakes and wobbles in its rotation that gave hints of a still molten core.
Now, a rock collected more than 36 years ago during Apollo 17, the last human visit to the Moon, reveals that the molten core may have once churned and generated a magnetic field.The lasting impression left by the Apollo missions is of a Moon that is gray, dusty,... more

A meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami that flooded the New York City region, a new study says (New York City and Long Island map).
It's not known whether any ancient settlements were in the path of the proposed killer waves, but "any significant tsunami today would be devastating and likely to flood places like lower Manhattan," Vanderbilt University geologist Steven Goodbred said.
Tsunamis are typically triggered by seismic events. An undersea earthquake, for example, caused the catastrophic 2004 Indian Ocean tsunami. But meteorite strikes have also been known to spark the killer waves.
In the New York area, "there are no exploding volcanoes and there probably haven't been" for millions of years, said study co-author Katherine Cagen of Harvard University. "The same goes for [major] earthquakes."
Cagen, however, recently found signs of a meteorite impact in sediments taken from several sites along the Hudson River, which forms the border between New York City and New Jersey.
The evidence included deformed rocks; rare microscopic "nanodiamonds"; and microscopic, perfectly round rocks called spherules, which form when molten and vaporized rock are flung into the air by a space impact and then solidify in the temporary vacuum created by the blast.
Nothing as big as a crater has been found, but Dallas Abbott, a Columbia University impact expert, estimates that the space rock would have had a diameter of between about 165 feet (50 meters) and 490 feet (150 meters). Any smaller, and a major wave would not have formed and the rock would have exploded before hitting Earth. Any bigger, and the strike would have created "impact glass"—forged in the extreme heat of an impact blast—which has not been found as of yet.
Abbott presented her team's research this month at the annual meeting of the American Geophysical Union in San Francisco.A meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami... more

A meteorite that was recorded falling in Alberta could set a record as Canada's largest meteor fall. Fragments of the 4 billion year old piece of rock have been steaming in to the University of Calgary where they are being stored in nitrogen. So far 40kg have been found and an estimated 50kg are still to be found. A large snow fall has hampered efforts but pieces are still coming in do to the large size.
For scientist this is a rare opportunity. The meteorite is high in iron content and its fall did not produce high temperatures, giving us a look at when the solar system was still in its infancy.A meteorite that was recorded falling in Alberta could set a record as Canada's... more
