Astronomers have obtained new images of the mysterious interstellar object 3I/ATLAS that reveal a new feature: the fastest comet ever observed has now grown a tail. A Tail and a Glowing ComaThe discovery of the comet’s tail was made during analysis of images obtained by the Gemini South telescope, located in the Chilean Andes. In addition to the comet’s gassy tail, the images also showed 3I/ATLAS’s glowing coma, or halo of dust and gas encircling it. NASA Weighs In on 3I/ATLASFor several weeks, 3I/ATLAS has garnered attention based on speculations that the object could be more than just a comet. “It has some interesting properties that are a little bit different from our solar system comets, but it behaves like a comet,” Statler recently told The Guardian.
