“The dark, smooth and lustrous aspect of this target, and its sort of spherical shape attracted the attention of some MSL scientists”
The Mars Curiosity Rover captured the photograph of the object on October 31.
NASA researcher Pierre-Yves Meslin said the team were amazed to see the “egg”.
He said: “The dark, smooth and lustrous aspect of this target, and its sort of spherical shape attracted the attention of some MSL scientists when we received the Mastcam images at the new location.”
The Curiosity mission has already determined that the planet once offered conditions favourable for microbial life.
But now NASA may have stumbled across real evidence of potential life.
Though despite the find, other experts believe the object is likely to be made of nickel iron and may be a meteorite.
The main goal for Curiosity’s second extended mission, which began last month, is to investigate how ancient environmental conditions changed over time.
Mars, which is close to an asteroid belt, is often the site of meteorite discoveries.
It is believed the “egg” could have become molten as it entered the planet’s atmosphere before hardening again because of the smoothness of its surface and deep grooves.
Curiosity had found its first iron meteorite two years ago after landing on the planet for the mission in 2012.
Curiosity was launched five years ago.
It was revealed yesterday that aliens are going to get in touch with us soon and Earth is prepared.
