Nickel atoms detected in the cold gas around interstellar comet 2I/Borisov

Astronomers have discovered nickel atoms in the cold gas surrounding interstellar comet 2I/Borisov, revealing new information about an alien icy world. The presence of nickel, a heavy element not typically observed in cold environments, suggests the comet's composition is influenced by a short-lived nickel-bearing molecule.
