Description: ESO’s Very Large Telescope (VLT) has obtained new images of 3I/ATLAS, an interstellar object discovered last week. Identified as a comet, 3I/ATLAS is only the third visitor from outside the Solar System ever found, after 1I/ʻOumuamua and 2I/Borisov. Its highly eccentric hyperbolic orbit, unlike that of objects in the Solar System, gave away its interstellar origin. In this image, several VLT observations have been overlaid, showing the comet as a series of dots that move towards the right of the image over the course of about 13 minutes on the night of 3 July 2025. The data were obtained with the FORS2 instrument, and are available in the ESO archive.
