Two lakes found under ice cap in Canadian Arctic may offer clues to possible life on Europa, the icy moon of Jupiter.
Two super-salty lakes discovered under ice in the Canadian Arctic could help scientists search for life on other worlds.
Analysis of publicly available radar data led scientists to the unexpected discovery of the two lakes, located beneath 550 to 750 metres of ice in the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic.
“We weren’t looking for subglacial lakes. The ice is frozen to the ground at the Devon Ice Cap, so there shouldn’t be liquid water there,” said Anja Rutishauser, PhD student at the University of Alberta, who made the discovery while studying radar data from NASA to describe the geology surrounding the ice cap.
Sending electromagnetic waves through the ice essentially allowed the scientists to see through the ice.
“We saw these radar signatures telling us there’s water, but we thought it w...
