Scientists discovered mysterious tube-like structures in desert rocks of Namibia, Oman, and Saudi Arabia that do not match known geological processes, suggesting they may be formed by an unknown microbial life, possibly from ancient times, though their current existence remains uncertain.
A photo taken by NASA's Curiosity rover on Mars shows a rock formation resembling a mushroom, sparking speculation about extraterrestrial life. Scientists explain that the structure is likely a natural geological formation called a concretion, formed by mineral deposits in water billions of years ago, and emphasize that the harsh Martian environment makes the presence of surface life highly unlikely.
NASA's InSight lander measured the largest marsquake ever recorded in May 2022, revealing that the Martian crust is "like heavy armor" in some locations, according to a new study. The team's research showed that the crust of the Red Planet has a thickness that ranges from an average of 26 to 35 miles (42 to 56 kilometers), but its thickest extent is double that: 56 miles (90 kilometers). The team's discovery of a thick Martian crust in some places also sheds some light on how the planet generates heat, and how this has evolved over the Red Planet's history.
