Evidence of cataclysmic planetary collision 1 800 light years from Earth
In December 2021, astronomers observed unprecedented fluctuations in the light of a star identified as ASASSN-21qj, located 1 800 light years away from Earth. Now, a study published in Nature suggests these fluctuations were the result of a colossal collision between two giant planets, potentially providing a rare opportunity to witness the birth of a new planet.
