Massive new NASA exoplanet catalog reveals 126 extreme and exotic worlds

by
Lots of different exoplanet illustrations neatly organized in a grid pattern. They

A new catalog of 126 extrasolar worlds contains a plethora of newly discovered planets – some extreme and exotic in nature, but others could potentially support life as we know it. The mix of planets in the catalog is further evidence of the vast and wild variety of worlds beyond our cosmic backyard; it even … Read more

NASA space telescope finds Earth-sized exoplanet that’s ‘not a bad place’ to hunt for life

by
A red orb toward the top left of the screen and an Earth-looking world toward the bottom right.

Scientists using a NASA space telescope have discovered a tantalizing world. It’s about the size of Earth, is remarkably close to our solar system, and could be comfortable for life as we know it. The extrasolar planet, or ‘exoplanet’, called Gliese 12 b, orbits a small and cool red dwarf star located only about 40 … Read more

Gliese 12 b, which orbits a cool, red dwarf star just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres. In this artist’s concept, Gliese 12 b is depicted while maintaining a rarefied atmosphere. Credit: NASA/JPL-Caltech/R. Pain (Caltech-IPAC) Scientists have discovered Gliese 12 b, … Read more

Newly discovered exoplanet could have temperatures similar to Earth, astronomers suggest

by

A newly discovered exoplanet, estimated to have a remarkably moderate surface temperature, is suddenly one of the most intriguing objects in our immediate sky. This Venus-sized rocky world passes by a red dwarf star, offering astronomers a rare opportunity to investigate whether such planets can maintain their atmospheres and possibly support life. How will time … Read more
