Update Fall of the meteorite on the Ural Mountains

"According to preliminary assessment, it is not a space object created by technology and classified as thermogenic meteorite that flew about 30 kilometers per second at low altitude," reads a statement released today by Roscosmos.

"Similar objects accidentally enter the atmosphere and is a little predictable phenomenon," stresses the Roscosmos.

The Defense Ministry of Russia has also confirmed this information.

The populist leader Vladimir Zhirinovsky had accused the U.S. of "having experienced a new kind of weapon in the territory of Russia."

The fall of the meteorite, which broke up upon entering the atmosphere and hit six cities of the Ural Mountains, according to the latest data from the Ministry for Emergency Situations of Russia, led 474 injured, 14 of whom had to be hospitalized.

Hundreds hurt as meteorite strikes central Russia

About 400 people were injured when a meteorite shot across the sky in central Russia on Friday sending fireballs crashing to Earth, smashing windows and setting off car alarms.

Residents on their way to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave.

The meteorite raced across the horizon, leaving a long white trail in its wake which could be seen as far as 200 kilometres away in Yekaterinburg. Car alarms went off, windows shattered and mobile phones worked only intermittently.
Chelyabinsk city authorities said about 400 people sought medical help, mainly for light injuries caused by flying glass.

“I was driving to work, it was quite dark, but it suddenly became as bright as if it was day,” said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains.

“I felt like I was blinded by headlights,” he said.

No fatalities were reported but President Vladimir Putin, who was due to host Finance Ministry officials from the Group of 20 nations in Moscow, and Prime Minister Dmitry Medvedev were informed.

A local ministry official said the meteor shower may have been connected with an asteroid the size of an Olympic swimming pool that was due to pass Earth at a distance of 27,520 kilometres but this could not be confirmed.
Windows were shattered on Chelyabinsk’s central Lenin Street and some of the frames of shop fronts buckled.

A loud noise, resembling an explosion, rang out at around 9.20 a.m. local time. The shockwave could be felt in apartment buildings in the industrial city’s centre.

“I was standing at a bus stop, seeing off my girlfriend,” said Andrei, a local resident who did not give his second name. “Then there was a flash and I saw a trail of smoke across the sky and felt a shockwave that smashed windows.”
A wall was damaged at the Chelyabinsk Zinc Plant but there was no environmental threat, a plant spokeswoman said.

Such incidents are rare. A meteorite is thought to have devastated an area of more than 2,000 square kilometres in Siberia in 1908, smashing windows as far as 200 kilometres from the point of impact.

The Emergencies Ministry described Friday’s events as a “meteor shower in the form of fireballs” and said background radiation levels were normal. It urged residents not to panic.

Chelyabinsk city authorities urged people to stay indoors unless they needed to pick up their children from schools and kindergartens. They said a blast had been heard at an altitude of 10,000 metres, apparently signalling it occurred when the meteorite entered Earth’s atmosphere.

NASA Rules Out Earth Impact in 2036 for Asteroid Apophis

NASA scientists at the agency's Jet Propulsion Laboratory in Pasadena, Calif., effectively have ruled out the possibility the asteroid Apophis will impact Earth during a close flyby in 2036.

The scientists used updated information obtained by NASA-supported telescopes in 2011 and 2012, as well as new data from the time leading up to Apophis' distant Earth flyby yesterday (Jan. 9). Discovered in 2004, the asteroid, which is the size of three-and-a-half football fields, gathered the immediate attention of space scientists and the media when initial calculations of its orbit indicated a 2.7 percent possibility of an Earth impact during a close flyby in 2029.

Data discovered during a search of old astronomical images provided the additional information required to rule out the 2029 impact scenario, but a remote possibility of one in 2036 remained - until yesterday.

"With the new data provided by the Magdalena Ridge [New Mexico Institute of Mining and Technology] and the Pan-STARRS [Univ. of Hawaii] optical observatories, along with very recent data provided by the Goldstone Solar System Radar, we have effectively ruled out the possibility of an Earth impact by Apophis in 2036," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at JPL.

"The impact odds as they stand now are less than one in a million, which makes us comfortable saying we can effectively rule out an Earth impact in 2036.

Our interest in asteroid Apophis will essentially be for its scientific interest for the foreseeable future." The April 13, 2029, flyby of asteroid Apophis will be one for the record books. On that date, Apophis will become the closest flyby of an asteroid of its size when it comes no closer than 19, 400 miles (31,300 kilometers) above Earth's surface.

"But much sooner, a closer approach by a lesser-known asteroid is going to occur in the middle of next month when a 40-meter-sized asteroid, 2012 DA14, flies safely past Earth's surface at about 17,200 miles," said Yeomans.

"With new telescopes coming online, the upgrade of existing telescopes and the continued refinement of our orbital determination process, there's never a dull moment working on near-Earth objects."

Large asteroid belt around the star Vega

Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space Telescope and the European Space Agency's (ESA) Herschel Space Observatory, in which NASA plays an important role.

The discovery of an asteroid belt-like band of debris around Vega makes the star similar to another observed star called Fomalhaut. The data are consistent with both stars having inner, warm belts and outer, cool belts separated by a gap. This architecture is similar to the asteroid and Kuiper belts in our own solar system.

What is maintaining the gap between the warm and cool belts around Vega and Fomalhaut? The results strongly suggest the answer is multiple planets. Our solar system's asteroid belt, which lies between Mars and Jupiter, is maintained by the gravity of the terrestrial planets and the giant planets, and the outer Kuiper belt is sculpted by the giant planets.
