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
