Original excerpt
The interstellar comet emitted methane, a potential biosignature, as it passed the sun, physicist Avi Loeb says.
Key claims
- →Interstellar comet 3I/ATLAS detected methane emissions near the sun
- →Methane is identified as a potential biosignature
- →Avi Loeb proposes these emissions indicate possible extraterrestrial organisms
UAP Insight Analysis— AI generated, not official
Physicist Avi Loeb claims the interstellar comet 3I/ATLAS emitted methane signatures consistent with biosignatures as it approached the sun, suggesting possible microbial life.
Alternative explanation
Methane can be produced through non-biological processes in cometary outgassing, and biosignature claims require additional evidence to rule out abiotic origins.
