Mars is apparently full of mysterious, super-dense blobs deep under its surface—possibly leftovers from ancient 'failed planets' that never made it big. Scientists found these weird structures using Marsquake data from NASA’s InSight lander, and they’ve been chilling there for billions of years. Unlike Earth, Mars doesn’t have tectonic plates, so these blobs are basically time capsules from the solar system’s wild early days. Space is wilder than we thought! #Science #Mars #SpaceMystery
