Earth-Sized Planet Found Just 40 Light-Years Away — Could It Be Habitable? #Exoplanet #SpaceDiscovery #NASA 📝 Detailed YouTube Description with Hashtags Astronomers have discovered Gliese 12 b, an Earth-sized planet located just 40 light-years away, making it one of the closest potentially habitable worlds ever found. Detected using NASA’s TESS telescope, the planet orbits a calm red dwarf star every 12.8 days, placing it inside the star’s habitable zone where liquid water could exist. What mak

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
