Astronomers just caught something wild: two planets smashing into each other 11,000 light-years away. A University of Washington researcher stumbled on it by accident while digging through old telescope data from 2020. The star Gaia20ehk started flickering strangely in 2016, then "went completely bonkers" in 2021. Turns out, it wasn't the star — it was planetary wreckage blocking its light.
