  Russian meteor: 17 metres wide, weighed 10.000 tons and crashed at 64.373 km/h says NASA

  

  The meteor that exploded over Russia Friday was slightly larger than previously thought and more powerful, too, NASA scientists say. The explosion over the city of Chelyabinsk, on Friday injured more than 1,000 people and blew out windows across the region in a massive blast captured on cameras by frightened witnesses.

  NASA IceBridge on its fourth edition to study Antarctica’s polar ice changes

  

  Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice have started another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier.

  Rapidly eroding ice cap and thickness makes the Arctic even more vulnerable

  

  Arctic has lost more sea ice this year than at any time since satellite records began in 1979, Nasa says. Scientists involved in the calculations say it is part of a fundamental change. What is more, sea ice normally reaches its low point in September so it is thought likely that this year's melt will continue to grow.

  Greenland’s massive ice sheet “unprecedented” melt puzzles Nasa scientists

  

  Greenland's massive ice sheet has melted this month over an usually large area, Nasa has said. Scientists said the “unprecedented” melting took place over a larger area that ever detected in three decades of satellite observation.

  Extended blooming phytoplankton discovered under thinning Arctic ice cap

  

  Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition punched through three-foot thick sea ice to find waters richer in microscopic marine plants, essential to all sea life, than any other ocean region on Earth.

  Global average temperature in 2011 the ninth warmest in modern records

  

  The global average temperature in 2011 was the ninth-warmest in the modern meteorological record, continuing a trend linked to greenhouse gases that saw nine of the 10 hottest years occurring since the year 2000, NASA scientists said this week.

  Sixty years later NASA Gravity Probe B confirms predictions by Albert Einstein

  

  Nasa's Gravity Probe B has produced remarkable new confirmation of some key predictions by Albert Einstein. The satellite's observations show the massive body of the Earth is very subtly warping space and time, and even pulling them around with it.
