NASA's Perseverance rover has sent home pictures of a mysterious black-and-white striped rock, the likes of which scientists have never seen before on Mars.

A new map that details gravitational anomalies on Mars has revealed 20 mysteriously dense blobs, including a dog-shaped mass, buried below the planet's north pole. And researchers have no clear idea where they came from.

Researchers have recreated the bizarre spider-like features seen on the surface of Mars for the first time ever. The breakthrough could help unravel further mysteries surrounding the static Martian arachnids.
