Water Discovered in the Atmosphere of an Exoplanet in the Habitable zone. It Might Be Rain

Huge news! Scientists have discovered water in the atmosphere of an exoplanet in the habitable zone. It's a Super-Earth orbiting a red dwarf.

and it’s twice as large as Earth, and about 8 times as massive

It wouldnt be much use for us if we ever managed to travel there. But if life did evolve in that Gravity im sure its morphology would be fascinating.

8*mass & 2*size equals roughly ~2g, not comfortable, but not impossible.

Seems that you are correct. I stand corrected. Yes 2G would be ok.
Unless you come from American Samoa or the state of Alabama.

It's probably not habitable for humans, or even life as we know it, for reasons other than gravity--the hydrogen-helium atmosphere comes to mind--but it's still very neat that we can discern the presence of water on an object so close to Earth's size at 124 light-years distance.

When this gets lanuched (finally) Our ability to look for chemical signatures in atmospheres at a distance will greatly improve.

Yeah, a lot of hopes riding on the Jame's Webb Space Telescope. Hopefully everything goes smoothly.

Nice one. Thanks for posting.

Interesting, need to go to the gym before i get there.

Ah, sadly the parent star wasn't in the right catalogues to have been imported into the E: D universe when they were setting up the galaxy, so you can't go visit K2-18. However, if I've got my coordinate transform correct, Col 285 Sector OE-D b14-4 is within a couple of light years of where it would be, and by happy coincidence is of the same stellar type (M3V red dwarf). Its currently one of those boring uninhabited systems of non-landable icy bodies, so Frontier certainly wouldn't be putting anyone out if they added a suitable planet to the system!

Although after some searching, I haven't been able to find a close match to this planet. It seems like Stellar Forge does not like to kick out planets in this mass range with such a large radius.
