Overview
- 3I/ATLAS is expected to make its closest approach to Earth on December 19, passing at roughly 167 million miles.
- NASA’s Hubble Space Telescope imaged the object on November 30 and resolved a glowing coma consistent with an active comet.
- European Space Agency observers report sustained outgassing, with additional JUICE spacecraft data slated to arrive in late February.
- Recent observations also detected gaseous methanol and hydrogen cyanide, chemical species tied to comet activity and prebiotic chemistry.
- Most scientists describe 3I/ATLAS as a natural comet, though Harvard’s Avi Loeb advances a minority technological hypothesis and warns of lacking response protocols, while celebrity and tabloid claims remain unsubstantiated.
