Astronomers just found a rare rogue planet drifting alone through space, untethered from any star. 🪐 These rogue planets are nearly impossible to detect, but this one gave itself away when it briefly passed in front of a distant star, bending the starlight through gravity, a phenomenon called “gravitational microlensing”. The event was observed from two locations: Earth and ESA’s Gaia spacecraft, a million miles away. That dual perspective allowed scientists to calculate its mass, about three-q
