Combined image of interstellar comet 3I/ATLAS formed by 239 exposures of 50 seconds taken with the Two-metre Twin Telescope (TTT3) at the Teide Observatory. The brightness contours are superimposed on the comet. The apparent size in the sky is 9.8‘ x 8.8’, which corresponds to a cloud of gas and dust about 25,000 km long and 22,400 km wide. The image shows the orientation, scale and directions in which the Sun is located and in which the object is moving. This image is the result of joint work by the TTT science group and the solar system and low surface brightness groups of the Instituto de Astrofísica de Canarias. Credit: Miguel R. Alarcon, M.
