The alien comet 3I/ATLAS is roughly 7 miles (11.2 kilometers) wide, making it the largest interstellar object ever spotted, according to newly revealed photos from the Vera C. Rubin Observatory.
The detailed images, which were captured before the extrasolar entity was officially discovered, highlight the immense power of the record-breaking telescope and demonstrate how valuable it will be for finding future interstellar interlopers, researchers say.
