NASA Discovers New Findings on Mars’s Largest Volcano

NASA's recent findings highlight Olympus Mons, the largest volcano in the Solar System located on Mars, which stands over 27 km high and spans an area larger than Poland. Its massive size results from Mars's lack of tectonic activity, allowing repeated lava flows to build up over millions of years. Although dormant since about 25 million years ago, recent discoveries of frost suggest potential future activity or water presence, keeping scientists intrigued about this geological marvel.

Scientists Discover Planets Can Generate Their Own Water

Scientists have discovered that water-rich exoplanets, especially sub-Neptunes close to their stars, can produce their own water through high-pressure reactions between silicate melts and hydrogen in their atmospheres, challenging previous theories about their formation and composition.

Springtime Discoveries Uncover Hidden Martian Dunes

Experiments simulating Martian conditions reveal that the gullies and sinuous features on Mars' dunes are carved by the sublimation of dry ice, which burrows into the sand and ejects material, explaining their unique shapes and formation process.

Mercury Continues to Shrink, Contracting Up to 11 Kilometers

Research indicates that Mercury has shrunk by approximately 2.7 to 5.6 kilometers since its formation, primarily due to cooling and faulting, with a new method providing more consistent estimates of this contraction. This insight enhances understanding of Mercury's thermal evolution and could be applied to study other planetary bodies with faults.
