Liquefy glaciers has accelerated threefold


Approximate fifty leading experts on climate science in the world have studied the thaw out of polar ice, which is the main reason for the increase in water level in the oceans. Space satellites have helped researchers identify how decline in volume of glaciers in the Arctic, Greenland and Antarctica. It turned out that the glaciers are melting three times faster than a couple of decades ago.

Galactic hobbits


What do we know about galaxies, Hobbits, and why they have such a peculiar name?

The name "hobbit galaxies" ("hobbit galaxy") - this is quite a new term used to describe galaxies that are smaller and dimmer than the dwarf galaxies. By the number of stars that inhabit such galaxies (hundreds of thousands of stars), these objects occupy an intermediate position between dwarf galaxies and star clusters.

In Mercury's polar craters found vast reserves of water


The American space survey Messenger has confirmed the existence of water ice in deep craters at the north pole of Mercury.

"It must be the last thing you might expect from the nearest planet to the sun - is water ice. But due to the low inclination of Mercury craters near the poles are in the shade all year, and there is extremely cold, "- explained Matthew Sigler's Jet Propulsion Laboratory NASA.
