NASA has discovered an interstellar comet that's wandered into our backyard. The space agency spotted the object with the Atlas telescope in Chile earlier this week, and has confirmed it was a comet from another star system.

Astronomers are tracking a newly spotted comet hailing from parts unknown, only the third time such an interstellar object has been observed visiting our solar system.

Astronomers have discovered a rare instance of a interstellar comet speeding through the solar system. The 3I/ATLAS was first spotted on July 1 by the NASA-funded Asteroid Terrestrial-impact Last Alert System telescope.
