The interstellar object 3I ATLAS turned out to be surrounded by a giant cloud of carbon dioxide and dust. Its nucleus is less than 3 km across, but it looks like a huge snowball. This distorts our understanding of visitors from other stars.

🎯 This object is only the third known interstellar visitor after ‘Oumuamua and Comet Borisov.

🎬 The storyline echoes Arthur C. Clarke's 'Rendezvous with Rama': a mysterious object from interstellar space that challenges science.
