Discover the true size of 3I/ATLAS: at least 5 kilometers across and 10 times larger than previous interstellar visitors. Learn how scientists measured this mysterious object from another star system.
Marian Rudnyk explains why 3I/ATLAS unusual brightness and behavior can be explained by cryo-volcanic activity, comparing it to known comets like 29P/Schwassmann-Wachmann 1 and Halley.
Plasma Physicist Dr. John Brandenburg shares why he believes interstellar object 3I/ATLAS is not a comet, comparing it to Oumuamua and 2I/Borisov in light of unusual outgassing activity far from the Sun.
