NASA has identified an interstellar comet that's strayed into our vicinity. The space agency detected the fast-moving celestial body with the Atlas telescope in Chile earlier this week, confirming it as a comet from another star system.

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