It took astronomical observations spanning a period of over 20 years to actually detect it.

The most exciting thing about the find is that GJ 251c is situated in its star's Goldilocks zone - the region in which the temperature is 'just right' for liquid water to exist on a planet's surface.Unfortunately, though, it is simply too far away to determine whether or not it has an atmosphere and we don't currently have a telescope capable of analyzing it even if it does have one.

"While we can't yet confirm the presence of an atmosphere or life on GJ 251c, the planet represents a promising target for future exploration," said Penn State University's Prof Suvrath Mahadevan.

The next telescope that will be capable of analyzing the planet's atmosphere - the Habitable Worlds Observatory - sadly won't even launch until the 2040s.

Until then, all we can do is speculate.
