NASA’s Perseverance rover may have discovered its first meteorite on Mars, a 31-inch iron-nickel boulder named Phippsaksla found in Jezero Crater. Its pitted, coral-like texture and unusually high metal content resemble meteorites previously identified by Curiosity, Spirit, and Opportunity. Scientists are now analysing the rock’s composition in detail to determine...

A new analysis of NASA’s Fermi telescope data reveals a faint gamma-ray halo around the Milky Way’s core, matching predictions for annihilating dark-matter particles. Researchers say no known astrophysical source fits the signal, raising the possibility of the first direct evidence of dark matter. Experts, however, stress caution and call for verification in other...

A new study suggests that icy moons such as Mimas and Enceladus may host boiling subsurface oceans triggered by thinning ice shells and falling pressure. This low-temperature boiling could still support life beneath the surface. The research also explains geological features on larger icy moons and strengthens their potential as sites for finding extraterrestrial life...
