African meteorite shows Mars was volcanically active for two billion years

Mars was volcanically active for at least two billion years – almost half of the Red Planet’s history. By analysing a meteorite discovered in Africa in 2012, researchers have been able to show Mars has some of the longest-lived volcanoes in the entire solar system. The 200g meteorite, Northwest Africa 7635, was found in Algeria. Feb 2, 2017

Animation shows polar ice cap changes over a year

Animation shows polar ice cap changes over a year

The European Organisation for the Exploitation of Meteorological Satellites has produced an animation that summarises the status of sea ice concentration in the Arctic and Antarctic regions over the whole year.The group published the animation amid reports of how the ice levels at the polar caps are at a low. It cited a report stating the Arctic low ice level is due to global warming and unusual weather events while Antarctica’s low is due to a natural variability. In the animation above you can see how Arctic and Antarctic sea ice extent changed during the year. Jan 31, 2017
