A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away.

NASA discovered five exoplanets orbiting stars in under 24 hours, challenging planetary models and providing insights into ...

Named HD 20794 D, the newly discovered exoplanet orbits a star similar to the Sun, and researchers believe it may be able to sustain liquid water, which is vital for life, as we know it, to exist.

It was, of course, a great joy for me when we could confirm the planet’s existence,” said Dr. Cretignier. “It was also a ...
