A new image of comet 3I/ATLAS has revealed that the interstellar visitor is glowing green and hiding its tail, but that doesn't mean there's anything wrong with it.
Qicheng Zhang, a researcher at the Lowell Observatory in Arizona, used the observatory's powerful Discovery Telescope to make fresh observations of the comet as it zoomed away from the sun on Wednesday (Nov. 5). The comet recently became visible again after swinging around the far side of our star.
