  • Origins of Russian fireball found: Scientists say... [similar orbit to asteroid 2014 UR116]

    ...the Kola fireball had a 'disturbingly similar' path to asteroid 2014 UR116, which is due to pass by the moon in 2017. Spotted on April 19 last year, researchers used camera footage to help recreate its trajectory and hunt down any remaining fragments... This led researchers to the Annama meteorite, which is an ordinary H5 chondrite -- a group of space rocks with high strength that make up 31 per cent of meteorite falls. The computer model compared the orbit of Annama, a 1,100lb (500kg) rock, with the evolution of a dozen orbits of near-Earth asteroids... Vladimir Lipunov, a professor...
  • Russian Meteor's Origin Remains Mysterious 2 Years Later

    Originally, astronomers thought that the Chelyabinsk meteor came from a 1.24-mile-wide (2 kilometers) near-Earth asteroid called 1999 NC43. But a closer look at the asteroid's orbit and likely mineral composition, gained from spectroscopy, suggests few similarities between it and the Russian meteor. However, "the composition of [the] Chelyabinsk meteorite that was recovered after the event is similar to a common type of meteorite called LL chondrites," he added. "The near-Earth asteroid has a composition that is distinctly different from this." More generally, Reddy and his colleagues' work showed that it is difficult to make predictions about what particular asteroid could...

    This is the moment an explosively bright orange flash briefly illuminated the sky above a remote region in central Russia. Locals compared the bright orange glow with what they would have expected from a nuclear explosion and many managed to capture the images in Russia’s Sverdlovsk region in the Urals in pictures and video. But despite the ample illustrations online, neither astrologist's or emergency services in the region so far have managed to come up with an explanation for exactly what is happening. Scientist Viktor Grokhovsky, who is a member of the meteorites committee of the Russian Academy of Sciences,...

    An extraordinary bright orange flash has lit up the sky in Russia’s Sverdlovsk region in the Urals. While locals captured the massive ‘blast’ on numerous cameras, both scientists and emergency services still struggle to explain the unusual event. Dark evening skies in the town of Rezh in Sverdlovsk region near Russia's Ekaterinburg turned bright orange for some ten seconds on November 14, with the event being caught on several cameras by the locals. A driver filmed the massive flash with his dashcam, later posting the video on YouTube, with more people commenting they’ve seen it too. Teenagers in the town...

    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...

    Chelyabinsk, a large city in western Russia, was best known for producing tractors and professional hockey players until the morning of February 15, 2013, when a 19-meter-wide meteor screamed through the sky and exploded with the force of 500 kilotons of TNT. The meteor generated a fireball many times brighter than the sun, so powerful it even caused sunburns. The shock wave blew out windows and knocked residents off of their feet, injuring more than 1,200. The object was the largest to strike Earth in more than a century...

    Anomalous zones of Russia: Arkaim town Four thousand years ago the local dwellers suddenly left the town Arkaim located in the south of the present Chelyabinsk Region and burnt the empty settlement. The town had a circular structure coordinated with the stars order. Many believe in mystical characteristics of the area and link it with the legends of ancient Siberia and the Urals. Specialists of the monitoring station of anomalies` research in the Urals claim that the specialized national park-museum Arkaim is a vast anomalous zone. Arkaim was found by an archaeological expedition of the State University of Chelyabinsk in...

May 8 (Interfax) - The chance of a large asteroid hitting our planet in the next 100 years is "extremely slim," astronomer Sergei Smirnov of the Pulkovo Main Observatory told journalists. Smirnov dismissed as unfounded reports that a giant asteroid could strike the Earth in the summer of 2008 and said this is clear from experts' calculations. U.S. astronomers have lately been closely monitoring a large newly discovered asteroid, which they said has a very little chance of colliding with the earth. The odds of...

    PARIS, Oct 13: A Russian meteorite that crashed two weeks ago in Siberia, but whose existence is being played down by Russian authorities, is said to be "one of the great events of the century" by French space specialist Antonella Barucci. Miss Barucci, a meteorite specialist employed by the Paris Observatory said that the Russian metorite, which fell October 3 in a remote region of Siberia "could be the largest and most important meteorite to fall on earth since the last one that fell in 1908, also on Siberia." The new Siberian meteorite has also the added attraction, moreover, that...

  • Russian meteor created new 'dust layer' in stratosphere, researchers say

    Some of the asteroid's remnants crashed to the ground, but hundreds of tons of dust remained in the atmosphere. A team led by NASA Goddard atmospheric physicist Nick Gorkavyi, who is from Chelyabinsk, wondered if it was possible to track the cloud using NASA's Suomi NPP satellite. "Indeed, we saw the formation of a new dust belt in Earth's stratosphere, and achieved the first space-based observation of the long-term evolution of a bolide plume," Gorkavyi said in a statement. Initial measurements 3.5 hours after the meteor explosion showed the dust 25 miles high in the atmosphere, speeding east at 190...

    NASA's checked its space rock maths and it's not good news "If you look at the number of impacts detected by US government sensors over the past few decades you find the impact rate of kiloton-class objects is greater than would be indicated by the telescopic surveys," said Bill Cooke, meteoroid environment office lead at NASA’s Marshall Space Flight Center at a press conference on Wednesday. "Over the past few decades we've seen an impact rate about seven times greater than the current state of the telescopic surveys would indicate."

    The fragment is so large that divers have been unable to lift it. Instead, it's been dragged along the bottom of the lake on a metal sheet. At 1,257 pounds--that's 570 kilos--It will be almost as big as the Holsinger meteorite, which landed in Arizona 50,000 years ago, and broke the scales when it was weighed earlier today. The rock will be tested to verify that it is from space and not from somewhere more mundane.

    YEKATERINBURG, September 25 (RIA Novosti) – While removing silt in an effort to fish out a huge chunk of meteorite from the bottom of a lake in Russia’s Urals, divers recovered a smaller meteorite on Tuesday, scientists said. “A meteorite chunk roughly the size of a human fist has been lifted from the depth of 13 meters [43 feet] in Lake Chebarkul,” the Urals Federal University said in a statement. According to scientists, the [remaining] huge chunk, weighting hundreds of metric tons, is buried under a 2.5-meter (8.2-foot) layer of silt. Scientists expect to remove the silt around it on...

    The Chelyabinsk meteorite either collided with another body in the solar system or came too close to the Sun before it fell to Earth, according to research announced today (Tuesday 27th August) at the Goldschmidt conference in Florence. "...We hope to find out more once the main body of the meteorite is raised from Chebarkul Lake," [says Dr Sharygin]. Surprisingly, the IGM team also found small quantities of platinum group elements in the meteorite's fusion crust. The team are only able to identify these elements as an alloy of osmium, iridium and platinum, but its presence is unusual as the...

The National Science Foundation- (NSF) supported stations are used to study earthquakes and the Earth's deep interior. While thousands of earthquakes around the globe are recorded by seismometers in these stations--part of the permanent Global Seismographic Network (GSN) and EarthScope's temporary Transportable Array (TA)--signals from large meteor impacts are far less common.
