Interstellar visitor Comet 3I/ATLAS was discovered just a week ago and ever since, astronomers across the world have been hard at work following it, trying to gather as much data on it as possible. The initial data on this object already suggested marked differences between it and the previous two known interstellar objects that crossed the 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.
