The newly discovered “interstellar visitor” 3I/ATLAS can be seen shining like a rainbow-colored string of cosmic pearls in a trippy new timelapse image captured by a telescope in Hawaii. The interloper was discovered on July 1, and within 24 hours NASA confirmed it was an interstellar object — an ejected piece of an alien star system that is shooting through …

Astronomers unveiled a striking new view of the interstellar visitor 3I/ATLAS on its journey toward the inner solar system. The Gemini North telescope in Hawai‘i captured the newfound comet passing through our cosmic neighborhood, about 290 million miles (465 million kilometers) from Earth. 3I/ATLAS was initially detected by ATLAS (Asteroid Terrestrial-impact Last Alert System) on July 1. It’s just the …

We’ve only known about its existence for a few short weeks, and already astronomers have been able to learn a lot about the mysterious interstellar comet 3I/ATLAS. The object was detected on 1 July 2025, and it made a big splash. Scientists rapidly discovered that it came from outside the Solar System – just the third known object to have …

The mysterious “interstellar visitor” that was recently spotted whizzing through the solar system may be around 3 billion years older than our cosmic neighborhood, a new study suggests. If confirmed, the alien interloper would be the oldest comet ever seen from Earth. And, if it’s made of what researchers think it is, it may also grow a spectacularly long tail …

On July 2, NASA revealed the existence of 3I/ATLAS, only the third ever interstellar object observed in the universe. These are objects that exist in interstellar space—the areas between stars—and which are not gravitationally bound to any star. The two other interstellar objects discovered to date are the comets 1I/ʻOumuamua and 2I/Borisov. 3I/ATLAS was discovered on July 1, when its …
