A spider-like scar on Jupiter’s moon Europa may indicate briny water beneath its icy crust. Researchers suggest impact-driven flows of salty liquid created starburst patterns resembling Earth’s lake stars. Future observations by NASA’s Europa Clipper mission could confirm these features, offering new insights into Europa’s subsurface oceans and potential habit…

Comet 3I/ATLAS, a rare interstellar visitor from beyond the solar system, is putting on a striking celestial show as it nears Earth. After passing perihelion in October, the comet brightened nearly tenfold and shifted from red to green due to glowing carbon molecules. Tracked closely by astronomers worldwide, this ancient object offers a unique opportunity to study th…
