Why it matters: clues to life’s origins, Earth's non-uniqueness, and the conditions that sustain life Next: JWST will probe atmospheres for biosignatures like oxygen, methane, and water

Haha, nice one! Seriously though, I read that 3I/ATLAS likely comes from the Milky Way's thick disk, full of ancient stars. Could be older than the Sun, which is wild to think about
