Astronomers have observed an object that originated from beyond our solar system, thought to be an interstellar comet, speeding through our celestial neighborhood.

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 may have just discovered the third interstellar object passing through the Solar System!" the agency's Operations account shared on Blue Sky. "ESA’s Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world."
