Rapid Brightening of Interstellar Comet 3I/ATLAS As It Nears Sun Surprises Scientists
An interstellar comet named 3I/ATLAS, only the third of its kind recorded, recently passed close to the sun, brightening at an unprecedented rate and appearing blue instead of the usual red. This unusual behavior has puzzled scientists, who monitored it using space-based solar observatories due to solar glare blocking Earth-based views. Researchers suggest the brightness surge may be caused by visible gas emissions as the comet neared perihelion.
