New space-based images reveal that 3I/ATLAS has become dramatically brighter and bluer than the Sun as it neared its closest approach, or what scientists call 'perihelion', on 29 October 2025.
Although the object is currently hidden from Earth-based telescopes due to its position behind the Sun's glare, several space observatories have continued tracking it. These include NASA's STEREO-A spacecraft, the SOHO observatory, and GOES-19, a weather satellite equipped with a compact solar camera.
