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,...

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...

Trajectory apparently began in near-Earth asteroid group ApolloAstroboffins have figured out where the Chelaybinsk meteorite came from using the power of maths and videos shot by witnesses in Russia.Click here for VideoJorge Zuluaga and Ignacio Ferrin of the University of Antioquia in Colombia have come up with a preliminary reconstruction of the orbit of the meteor, which smashed into the city in the Urals completely unexpectedly two weeks ago. By combing through the witness videos and using trigonometry, the astronomers have determined that the meteorite came from the Apollo class of asteroids in our Solar System's space rock belt. The...

Scientists say that it might weigh 60 tons The night was rather dull in the north-east of the Russian Irkutsk region on September 25, 2002. All of a sudden, night turned into day. A very bright glow covered the sky, it was hard to look at it. Those people, who happened to be outside at 2 a.m., saw a ball of fire that was flying very fast across the sky. Weird rusting sounds could be heard. A few seconds...

MOSCOW — A Russian emergencies official says at least one meteorite has fallen in Chelyabinsk region.

A Russian policeman works near an ice hole, said by the Interior Ministry department for Chelyabinsk region to be the point of impact of a meteor seen earlier in the Urals region, at lake Chebarkul some 80 kilometers (50 miles) west of Chelyabinsk February 15, 2013 (Reuters / Chelyabinsk region Interior Ministry) Russian scientists investigating the meteorite explosion in the Urals explained the nature of the event that caused havoc in the region. NASA said the shockwave force was equal to a 500-kiloton explosion – 30 times the Hiroshima blast.­The object was identified as a solitary 10-ton bolide by...

Scientists have calculated that 2014 UR116 asteroid will fly in dangerous proximity to Earth every three years. If it collides with the planet the energy of the explosion could be a thousand times greater than the impact of the Chelyabinsk meteorite. Vladimir Lipunov, a leading scientist on the team which discovered the asteroid this October, says the scientists now know its orbit and its period which is 3 years, but they cannot say precisely when the asteroid will approach the Earth. “We should track it constantly. Because if we have a single mistake, there will be a catastrophe. The consequences...

...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...

“While this approximately 400-meter sized asteroid has a three-year orbital period around the sun and returns to the Earth’s neighborhood periodically, it does not represent a threat because its orbital path does not pass sufficiently close to the Earth’s orbit … Any statements about risk for impact of discovered asteroids and comets should be verified by scientists and the media by accessing NASA’s Near Earth Object (NEO) program web site.”
