  • 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...

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.

While locals captured the massive ‘blast’ on numerous cameras, both scientists and emergency services still struggle to explain the unusual event.

    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...

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...

    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...

    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.

    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.

In the mist, a calm, mirror-like stretch of the Miass River flows through the foreground along a frosty landscape near Chelyabinsk, Russia. But the long cloud wafting through the blue sky above is the evolving persistent train of the Chelyabinsk Meteor. The vapor trail was left by the space rock that exploded over the city only 18 minutes earlier, causing...

More importantly, the duo was able to find out where Russia's most famous meteor was likely born. Using astronomy software developed by the U.S. Naval Observatory, Zuluaga and Ferrin gathered enough data to trace the meteoroid's origins in outer space. The information included the meteor's relative angle to the horizon, the shadows it cast, and video timestamps of...

This past Friday, the 50-meter wide asteroid 2012 DA14 just missed the Earth, passing not only inside the orbit of the Moon, which is unusually close for an asteroid of this size, but also inside the orbit of geosynchronous satellites. Unfortunately, asteroids this big or bigger strike the Earth every 1000 years or so. Were 2012 DA14 to have hit the Earth, it could have devastated a city-sized landscape, or stuck an ocean...

    At a news conference Friday, NASA scientists said the object that exploded over Russia was a “tiny asteroid” that measured roughly 45 feet across, weighed about 10,000 tons and traveled about 40,000 mph. The object vaporized roughly 15 miles above the surface of the Earth, causing a shock wave that triggered the global network of listening devices that was established to detect nuclear test explosions. The force of the explosion measured between 300 and 500 kilotons, equivalent to a modern nuclear bomb, according to Bill Cooke, head of the Meteoroid Environment Office at NASA's Marshall Space Flight Center in Huntsville,...

Initially traveling at about 20 kilometers per second, its explosive deceleration after impact with the lower atmosphere created a flash brighter than the Sun. This picture of the brilliant bolide (and others of its persistent trail) was captured by photographer Marat Ametvaleev, surprised during his morning sunrise session creating panoramic images of the nearby frosty landscape. An estimated 500 kilotons of energy was released by the explosion of the 17 meter wide space rock with...
