A recent study published in the Journal Science showed that Antarctica’s floating ice has decreased by as much as 18% over the last two decades.

Scientists for the study used data collected through satellite, which helped them get a longer range of snapshot of how the Antarctica ice sheet is responding to climate change.

The data collected for over two decades through satellite radar altimetry data, was gathered by missions of the European Space Agency between 1994 and 2012.

Researchers using the collected data created a high-resolution record of ice shelf thickness and were also able to it was not only the ice that was declining but the rate of decline was also accelerating.

With the help of observations by two powerful space telescopes, it has been found that the mysterious stuff that makes up about 85% of the universe’s total matter is weirder than ever considered.

According to the researchers, they observed huge colliding galaxy clusters and with the help of this they have deduced how dark matter behaves at the time of these vast encounters. So far, the researchers have studied a handful of cluster smashups.

About 72 galactic cluster collisions have been focused by a new survey by the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory. The survey has focused the collisions from all angles and at different times during their collisions.
