New study finds interstellar comet 3I/ATLAS exhibits typical comet behavior, with non-gravitational acceleration from outgassing, measured by NASA and ESA spacecraft, confirming it is not artificial.

Even the best telescopes can’t see exoplanets. It’s all about watching for jiggly stars, blue shifts, and transits.

Interstellar comet 3I/ATLAS was discovered just five and a half months ago, and in that time has taken the world by storm.
