The good news: two temperate planets with Earthlike-mass orbit a red dwarf star "only" 15 light years away. The bad news: that close to their star-0.045 AUs-they're tidally locked to it and the very hypothetical goldilocks climate band on the planet's surface suggests life not as we know it, if at all.

From phy.org:

An international scientific team led by researchers at the Instituto de Astrofisica de Canarias (IAC) has discovered the presence of two planets with Earth-like masses in orbit around the star GJ 1002, a red dwarf not far from the solar system. Both planets are in the habitability zone of the star.

"Nature seems bent on showing us that Earth-like planets are very common. With these two we now know 7 in planetary systems quite near to the sun," explains Alejandro Suarez Mascareno, an IAC researcher, who is the first author of the study accepted for publication in Astronomy & Astrophysics.

[...] The discovery was made during a collaboration between the consortia of the two instruments ESPRESSO and CARMENES. GJ 1002 was observed by CARMENES between 2017 and 2019, and by ESPRESSO between 2019 and 2021.

[...] "Either of the two groups would have had many difficulties if they had tackled this work independently. Jointly we have been able to get much further than we would have done acting independently," states Suarez Mascareno.
