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.

NASA has discovered a new interstellar comet that's currently located about 420 million miles away from Earth. The space agency spotted the quick-moving object with the Atlas telescope in Chile on Tuesday and confirmed it was a comet from another star system. The new interstellar comet's official name is 3I/ATLAS.
