The space agency spotted the quick-moving object with the Atlas telescope in Chile earlier this week, and confirmed it was a comet from another star system.

A new interstellar object, A11pl3Z, has been discovered in our solar system, marking the third such object to be observed. It was first discovered zipping near the sun this fall.

The interstellar object has been named 3I/Atlas by the International Astronomical Union’s Minor Planet Center.

Images of Jupiter taken by the Galileo spacecraft on July 22, 1994 show the luminous night-side impact of fragment W of Comet Shoemaker-Levy 9 with the planet.

With Jupiter some 534 million miles (860 million km) from Earth at the point of impact, the effects of the collision would prove hard to see. But one thing was certain: giant Jupiter was in for a ...

For Jupiter — 11 times wider than our planet — this was a small impact event. Large collisions, like from Comet Shoemaker-Levy 9 in 1994, left dark splotches on the Jovian surface, including ...
