A mysterious glacial lake on the surface of Pluto may be the answer to the possibility of life on this dwarf planet.
NASA has just published a picture depicting a deep pit shaped like a large lake that once existed on the surface of Pluto. The image also shows that the landscape around this deep pit is rocky, making it easy to associate a lake surrounded by hills and mountains.
Photos taken from July 2015 by the Long Range Reconnaissance Imager telescope on the New Horizons spacecraft.
NASA's prediction Slashgear page said that the flow on this dwarf planet formed from "millions or billions of years ago". Water appears on Pluto because of a combination of warm surface and high pressure atmosphere.
Of course, this image does not confirm that there is water existing on Pluto. NASA said that the hole is likely to contain liquid nitrogen gas, a gas found in the Spunik Planum Mountains, located in the center of the dwarf planet.
The chief investigator for the New Horizons ship, Dr. Alan Stern, said: "In addition to this lake image, we also found evidence of past water regulation channels on Pluto."
Information about the canal was not announced by NASA, but the agency said the canal could be 131 meters small but 32km wide.
