Chelyabinsk meteorite goes on show: Giant 600kg chunk is displayed after
being hauled from the bottom of a Russian lake

* Meteor seen over Russia in February while travelling at 41,600 mph
* Rock is believed to be one of the largest pieces to be found
* The chunk was recovered from the bottom of Chebarkul Lake last week
* It is now on display at the Chelyabinsk Regional History Museum

A huge piece of the Chelyabinsk meteorite, which crashed into Russia earlier
this year, has gone on display at a local museum.

The meteor fireball exploded over the Ural Mountains in February causing
a shock wave that smashed windows, damaged buildings and injured 1,600
people.

A 600kg rock, believed to be one of the largest pieces of this meteorite,
is currently being exhibited at the Chelyabinsk Regional History Museum
in the Southern Urals.

A 600kg fragment of the Chelyabinsk Meteorite at the Chelyabinsk Regional
History Museum is shown here. The chunk was recovered from the bottom
of Chebarkul Lake, some 60km west of Chelyabinsk. The meteorite exploded
over Chelyabinsk Region in February 2013

The chunk was recovered from the bottom of Chebarkul Lake, some 60km west
of Chelyabinsk, following a recovery operation last week.
 
The meteorite broke up into multiple pieces as it entered the atmosphere,
scattering space debris and creating a shock wave estimated to be as strong
as 20 Hiroshima atomic bombs.

Live footage on Russian TV showed a team pull out a 1.5-metre-long (five-foot-long)
rock from the lake after first wrapping it in a special casing while it
was still underwater.

Chelyabinsk, 900 miles east of Moscow and close to the Kazakhstan border,
took the brunt of the impact

THE CHELYABINSK METEOR CRASH

A meteor that blazed across southern Urals in February was the largest
recorded meteor strike in more than a century.

More than 1,600 people were injured by the shock wave from the explosion,
estimated to be as strong as 20 Hiroshima atomic bombs, as it landed near
the city of Chelyabinsk.

The fireball measuring 18 meters across, screamed into Earth's atmosphere
at 41,600 mph. Much of the meteor landed in a local lake called Chebarkul.

Other than the latest find, scientists have already uncovered more than
12 pieces from Lake Chebarkul since the February 15 incident. However,
only five of them turned out being real meteorites.

The rock broke up into at least three large pieces as scientists began
lifting it from the ground with the help of levers and ropes.

The scale itself broke the moment it hit the 570-kilogramme (1,255-pound)
mark.

"The rock had a fracture when we found it," one unnamed scientists told
the lifenews.ru website in a live transmission.

"It weighed 570 kilogrammes before the pieces fell off. And then the scale
broke," said the scientist.

"We think the whole thing weighs more than 600 kilogrammes," he said.

The Vesti 24 rolling news channel reported that divers had already recovered
more than 12 pieces from Lake Chebarkul since the February 15 incident.

The station cautioned that only four or five them turned out being real
meteorites.

Last week, scientists recovered what could be giant chunk of the Chelyabinsk
meteor from the bottom of the lake it crashed into in the Urals, Russia

The meteor fireball that crashed into Russia in February was part of a
656-foot wide asteroid called 2011 EO40. [Baalke - NOT TRUE!]

The fireball measuring 18 meters across, screamed into Earth's atmosphere
at 41,600 mph.

Six fragments of the meteorite have already been handed over to National
Museum of Natural History in Paris.

In August, NASA satellites made the unprecedented measurements of the
meteor which is thought to have released 30 times more energy than the
atomic bomb that destroyed Hiroshima.

Spanish astrophysicists analysed fragments of the meteor that were scattered
across the Russian town of Chelyabinsk, where the meteor landed, and claim
it came from the large Apollo asteroid that regularly crosses passed Earth
as it orbits the sun.

They added that the piece may have broken off because of the stress caused
by the gravitational pull of the planets and the sun, or could have been
caused by the asteroid hitting into something else during its orbit.
