Interstellar comet 2I/Borisov revisited as rare chemical sample

Discussion is turning again to 2I/Borisov, the comet discovered in 2019 as only the second confirmed interstellar object to pass through our solar system. Unlike comets from the Kuiper Belt or Oort Cloud, its hyperbolic trajectory means it originated around another star, offering scientists a rare direct chemical sample of a distant planetary system before it leaves forever.

Why now: Space enthusiasts are highlighting the comet's unique value as the only interstellar object scientists could study up close after 'Oumuamua.
