Astronomers have discovered a new giant exoplanet orbiting an M-dwarf star using NASA's Transiting Exoplanet Survey Satellite (TESS). The newly detected alien world, designated TOI-5344 b is similar in size and mass to Saturn. ...
With thousands of known exoplanets and tens of thousands likely to be discovered in the coming decades, it could be only a matter of time before we discover a planet with life. The trick is proving it. So far the focus has ...

Earth is our only example of a habitable planet, so it makes sense to search for Earth-size worlds when we're hunting for potentially-habitable exoplanets. When astronomers found seven of them orbiting a red dwarf star in ...
