Astronomers Found Something Cold and Wet Near Uranus
The icy moon Miranda is the latest satellite in our solar system to spark hope in the search for life beyond Earth.
The team published its study earlier this month in The Planetary Science Journal, suggesting the “plausible existence” of an ocean at least 100 kilometers (62 miles) thick on Miranda within the past 100 to 500 million years. “To find evidence of an ocean inside a small object like Miranda is incredibly surprising,” said Tom Nordheim, a planetary scientist at the laboratory and co-author of the recent paper, in a lab release. In the paper, the team wrote that orbital changes due to gravitational interaction between Miranda and other Uranian satellites may have generated a pulse of heat within the moon, creating a deep ocean at some point in the ancient past.
