Scientists have discovered a location on Mars that would be perfect for beach vacations, reports DailyMail.
An international team of researchers utilized data from the Chinese rover Zhurong to investigate hidden layers of rock beneath the planet's surface, which convincingly indicate the presence of an ancient northern ocean.
The new study provides the clearest evidence to date that the planet once had a vast body of water and a more habitable environment, the researchers stated.
The Zhurong rover landed on Mars in 2021 in an area known as Utopia Planitia and transmitted geological data about its surroundings in search of signs of ancient water or ice.
Unlike other rovers, it was equipped with a ground-penetrating radar that allowed it to explore the planet's interior using both low-frequency and high-frequency radar to penetrate Martian soil and reveal buried rock formations. By studying underground sedimentary deposits, scientists can now create a more comprehensive picture of the planet's history.
When the team analyzed the radar data, they discovered a layered structure resembling beaches on Earth. They identified formations known as "coastal" deposits, which slope downward toward oceans and form when sediments are transported by tides and waves into a large body of water.
When the team compared Martian data with radar images of coastal deposits on Earth, they found a striking similarity.
The angles of inclination observed on Mars fell right within the range of those seen in coastal sedimentary deposits on Earth.
This discovery suggests that Mars once had abundant water, further confirming the hypothesis of an ocean that covered much of the planet's northern pole.
Scientists also believe that a warm and humid environment conducive to life may have lasted for potentially tens of millions of years.
"We are finding places on Mars that once looked like ancient beaches and ancient river deltas. We have found evidence of wind, waves, and an abundance of sand—a true beach for relaxation," says co-author of the study, Benjamin Cardenas from Penn State University.
As a reminder, scientists have found evidence that there was once water on Mars. It is believed that the Red Planet lost its water billions of years ago when a sudden solar radiation burst from the Sun stripped away the Martian atmosphere. The loss of the Martian atmosphere meant that nothing prevented water vapor from escaping into space.
