A new study has shown that the rover uncovered polygonal wedges 35 kilometers underground—the first ever found below the planet’s surface. ... Earth year on Mars. In that time, the rover ...
Scientists discovered signs of an ocean's worth of liquid water miles below Mars' surface. The findings, based on Marsquake measurements by NASA's InSight lander, could help solve a mystery.
The animal was so unique that they had no idea what it was until they did genetic testing. It turned out to be a new species of sea slug that's perfectly adapted to the deep ocean.
Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a metabolically ...
That Mars once possessed large amounts of water was confirmed by isotope studies in a study published in March 2015, by a team of scientists showing that the ice caps were highly enriched with deuterium, heavy hydrogen, by seven times as much as the Earth. This means that Mars has lost a volume of water 6.5 times what is stored in today's polar ...
Some areas of the surface exhibit scalloped topography, a surface that looks like it was carved out by an ice cream scoop. This surface is thought to have formed by the degradation of an ice-rich permafrost. [16] Many features that look like pingos on the Earth are found in Utopia Planitia (~35–50° N; ~80–115° E). [17]
“We’ve identified more than 600 ancient lakes on Mars; there may have even been an ocean. So, it was a lot more Earth-like early on,” he said. So, it was a lot more Earth-like early on ...
An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [1] The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the ...
