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.

The ATLAS (short for Asteroid Terrestrial-impact Last Alert System) is a NASA-funded program developed by the University of Hawaii. It incorporates data from four ground-based telescopes, two in Hawaii, one in Chile, and one in South Africa, to scan the entire sky twice a night, looking for asteroids and other impactors.
