Astronomers are astonished by interstellar comet 3I/ATLAS, which has displayed what appear to be thruster-like gas jets and a striking blue glow—a phenomenon no natural comet has exhibited before.
The object, first detected by Hawaii's Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope, is now being investigated by NASA and the European Southern Observatory (ESO) to determine whether its unusual propulsion patterns are purely natural or something unprecedented in cosmic mechanics.
