A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope.
More than 5,000 planets have been discovered outside of the Solar System so far, but only a handful are in what is called the “Goldilocks zone” — neither too hot or too cold — that could host liquid water, a key ingredient for life.
The exoplanet LHS 1140 b is one of the few in this habitable zone, and has been thoroughly scrutinized since it was first discovered in 2017.
It sits 48 light years from Earth, which equates to more than 450 trillion kilometers (280 trillion miles) — relatively close in the vast distances of space.
The exoplanet had been thought to be a small gas giant called a “mini-Neptune” with an atmosphere too thick with hydrogen and helium to support alien life.
However, new observations from the Webb telescope have confirmed that the exoplanet is in fact a rocky “super-Earth”.
It is 1.7 times bigger than Earth, but has 5.6 times its mass.
5.6 times the mass = Humans couldn’t live on it even if we could reach it. An 85kg person (187 freedom units) would weigh 476kg or 1047pounderoos. You wouldn’t be able to move and barely breath. Your body would give out.
Oh, and the gravity well would be insurmountable to any technology we have today. So you’d never get off the planet once you got there (and died swiftly).
Killjoy…
F = (G₁G₂)/r²
You forgot the r
CRaaaap! my bad
Which likely means that anything that highly evolves there is trapped on the planet too, not even considering the extra weight requirements for them to take their water environment into space (assuming they’re marine creatures).
