Curiosity rover discovers peculiar metal sphere on Mars

NASA's Curiosity rover has been exploring the surface of Mars since 2012, and it recently came upon a rather puzzling find.

While scouring Mars' Mount Sharp earlier this week, the rover stumbled upon a small, metallic meteorite with some peculiar features, according to Daily Mail.

Arizona State University reports that a long-distance, laser-guided camera on board Curiosity captured two photographs of the little meteorite dubbed "Egg Rock" by scientists due to its shape.

The first image shows the object located atop a Martian-looking landscape:

While the second, which offers a more close-up view, highlights its somewhat smooth but uneven surface:

According to researchers at the university, "egg rock" is likely composed of a mixture of nickel and iron, which gives it it's metallic appearance.

While its appearance seems to be unique, meteorites are reportedly somewhat common on Mars.

Part of the reason is that many contain iron which tends to make them more durable and resistant to erosion.

This isn't the first strange thing found on Mars and it certainly won't be the last -- here are some more bizarre finds:
