These space stories made us look up in 2025

A rare interstellar comet, 3I/ATLAS, swept through our solar system in 2025, marking only the third known visitor from beyond our cosmic neighborhood. Scientists detected mini-lightning on Mars through rover microphones, captured the first artificial solar eclipses using synchronized spacecraft, and discovered that dark energy may change over time rather than remain constant. The year also brought the first successful private moon landing by Blue Ghost and revealed there's a tiny chance Earth could be ejected from the solar system if another star passes too close.
