Newfound 'super-Earth' exoplanets bear clues about atmospheres of alien worlds

The brightest red dwarf star in the sky may be the best chance astronomers have yet to analyze the atmospheres of alien worlds — and perhaps detect whether those worlds have life, a new study finds.

[Still, "we've been looking for exoplanets orbiting Gliese 887 for nearly 20 years, and while we saw hints of a planetary signal, it wasn't strong enough to convince ourselves that it was a planet," study lead author Sandra Jeffers, an astrophysicist at the University of Göttingen in Germany, told Space.com.]

This explains why the GJ 887 exoplanets are not currently listed at http://exoplanet.eu/, and, https://exoplanetarchive.ipac.caltech.edu/index.html I note some other reports indicate that the exoplanets are not likely habitable, "While none of these planets are likely to be habitable, their proximity nevertheless makes them prime targets for follow up not only with existing instruments but with next-gen telescopes that can better probe their atmospheres and compositions.", ref - https://skyandtelescope.org/astronomy-news/three-nearby-exoplanets-to-explore/

These new exoplanet reports range 4 to nearly 8 earth masses and AU Mic b reported near 58 earth masses. No planets like this in our solar system.
