K2-18b (planet) maybe 50% or more water

“This is the first time that we have detected water on a planet in the habitable zone around a star where the temperature is potentially compatible with the presence of life,” she said.

The habitable zone is the region around a star where temperatures are considered sufficiently benign for water to exist in liquid form on the surface of a planet.

The new planet is just over twice the size of Earth – in a planet category known as a “super Earth” – and has a temperature cool enough to have liquid water, between zero and 40C.

So we have gone from the drake equation to “hey we have a water planet about 100 ly’s away”?

I bet there is intelligent life in every sector of space. Screw that idiot Drake.
