JWST may be able to detect life on planets around red dwarfs within 16.3 light years
there are probably about 60 to 70 red dwarfs in that range as there are 86 within 20 LY.

EDIT: i just counted. there are exactly 60 known red dwarf stars within that range. 60 chances!

i counted the ones catelogued on this website: www.solstation.com...

Furthermore, unlike observations of Rayleigh scattering, this method can be used at wavelengths longer than 0.6 μm and is therefore potentially applicable, although challenging, to near-term planet characterization missions such as JWST. We also performed detectability studies for JWST transit transmission spectroscopy and found that the 1.06 and 1.27 μm dimer features could be detectable (SNR>3) for an Earth analogue orbiting an M5V star at a distance of 5 pc.

The detection of these features could provide a constraint on the atmospheric pressure of an exoplanet and serve as biosignatures for oxygenic photosynthesis.

Well I certainly hope they can stretch that range a lil bit, say out to 20.5L so that they can get some answers from gliese 581 which is supposed to be able to sustain life.

sometimes these scope out perform their design specs right out the gate. and some times they receive software upgrades that expand their capabilities.

i wouldn't worry too much about whether the range gets extended or not. right now though they calculate that it will be difficult task for that range because the signal to noise is a bit high. not too bad. but enough to challenge them.

60 stars though. who can complain? especially since statistically each dwarf should have at least one planet.

No complaints here that's some exciting stuff. Makes me want another scope, so I can at least pretend to help
