Analyzing data collected by China's Zhurong Mars Rover, an international team of researchers have detected buried evidence of beaches beneath a plain on the Red Planet.

The discovery, they say, is the strongest evidence yet that Mars's northern lowlands once sported an ocean that covered a third of the planet's surface—and which could have provided a habitable environment for microbial life.

"We're finding places on Mars that used to look like ancient beaches and ancient river deltas," explained paper author and geologist professor Benjamin Cardenas of Pennsylvania State University in a statement.
