Mars Meteorite Reveals New Evidence That Hot Water Flowed on Ancient Mars
"Scientists have found what seems to be the oldest direct evidence of hot water flowing on Mars during its ancient past," reports Space.com. "The discovery could further indicate that the Red Planet, despite its arid and desolate appearance today, may have been capable of supporting life long ago....
However, the Curtin University team discovered something even older within it: a 4.45 billion-year-old zircon grain that harbors the fingerprints of fluids rich in water. Team member Aaron Cavosie from Curtin's School of Earth and Planetary Sciences thinks this discovery will open up new avenues to understanding hydrothermal systems associated with the activity of volcanic magma that once ran through Mars. "Hydrothermal systems were essential for the development of life on Earth, and our findings suggest Mars also had water, a key ingredient for habitable environments, during the earliest history of crust formation...."
