Gliese 12 b’s estimated size may be as large as Earth or slightly smaller — comparable to Venus in our solar system. This artist’s concept compares Earth with different possible Gliese 12 b interpretations, from no atmosphere to a thick Venus-like one. Follow-up observations with NASA’s James Webb Space Telescope will help determine just how much atmosphere the planet retains as well as its composition. Credit: NASA/JPL-Caltech/R.

Exciting space-discovery alert!
Gliese 12 b is an Earth-size planet orbiting in the temperate zone around a nearby, stable red dwarf star. It's a Rosetta Stone world that will tell us a lot about how many superficially earthlike planets actually have the right conditions for life.
Are we rare? Are we common? Let's find out.
