Espinoza is a leader in the new massive James Webb Space Telescope study of rocky worlds, specifically to find out if planets ...

The planet, called 55 Cancri e or Janssen, is about 8.8 times more massive than Earth, with a diameter about twice that of our planet. It orbits its star at one-25th the distance between our solar ...

This planet is made of metal. GJ 367b is an extreme planet. This “super Mercury,” which orbits its star once every 7.7 hours, was first discovered by NASA’s TESS planet hunter in 2015.

Astronomers have spotted a small rocky planet that orbits perilously close to its host star disintegrating as its surface is vaporized by stellar heat, trailed by a comet-like tail of mineral dust ...

Also called Janssen, 55 Cancri e is a so-called super-Earth, a rocky planet significantly larger than Earth but smaller than Neptune, which orbits its star at a distance of only 2.25 million ...

An artist’s concept of GJ 486 b, a hot, rocky exoplanet orbiting a red dwarf star some 26 light-years away from Earth. Fresh data from the James Webb Space Telescope hints at water vapor in the ...

Researchers spotted a small, rocky planet orbiting the red dwarf known as Barnard’s Star, which is about 6 light years away from Earth.

However, the discovery of this water vapor in space could change all that, especially if it is from the rocky planet itself. Red dwarf stars like the star that GJ 486 b orbits are the most common.

Astronomers spotted a potential Earth-size rocky world orbiting a white dwarf, suggesting a future in which our planet outlives its star. By Jonathan O’Callaghan In six billion years the sun ...

55 Cancri e is a super-Earth planet that appears composed of diamond-like carbon — now, thanks to the JWST, astronomers have found the world has "grown" a second atmosphere.
