Surface gravity is a bit higher than Earth (12 m/s2), but totally bearable for humans. The smell of the atmosphere, on the other hand, will be something the first human visitors will never forget ;-).

I've been waiting to see atmospheric composition results from JWT. It seems like JWT was first put to work on other tasks. Anyone know of other studies from JWT like this?
What about just looking for oxygen in a planet's atmosphere?

Not all life needs (or wants) oxygen. Plenty of earthlings die quickly when exposed to it.

Third line of the summary:
> Gases found are the same as those produced by algae on Earth
AIUI, the sensors used for this discover don't look for just _one_ gas, but as many as possible. So Oxygen is probably included in that list.
Life needs more than just oxygen gas in the atmosphere to thrive. The right combination of gasses is a better signal that life could be there versus just the presence of one gas.

Plenty of abiotic oxygen sources, even on Earth.

And plenty of life for which Oxygen is a poison.

Might be a noise floor from all the interstellar medium oxygen?
You can filter by cycle & purpose - I think you want GO 4 then look at Exoplanet Atmospheres and Habitability?
