Harvard Astronomer Claims Interstellar Object Barreling Around Our Solar System Could Be Alien Technology

The object, estimated to be the size of a city block, is only the third known interstellar visitor to our solar system since scientists began keeping track of such things.

The Hubble telescope captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus.
