Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3

Astronomers Unveil New Earth-Sized Exoplanet Orbiting Ultra-Cool Dwarf Star

NASA’s TESS Discovers Fiery, Lava-Covered Exoplanet in Distant Star System

This artist's concept shows what the exoplanet 55 Cancri e could look like based on observations from NASA’s James Webb Space Telescope and other observatories. Observations from Webb’s NIRCam and MIRI suggest that the planet may be surrounded by an atmosphere rich in carbon dioxide (CO2) or carbon monoxide (CO). Researchers think the gases that make up the atmosphere could have bubbled out of an ocean of magma that is thought to cover the planet’s surface.

JPL scientist Vanessa Bailey stands behind the Nancy Grace Roman Coronagraph, which has been undergoing testing at JPL. About the size of a baby grand piano, the Coronagraph is designed to block starlight and allow scientists to see the faint light from planets outside our solar system. Credit: NASA/JPL-Caltech

Researchers spying for signs of life among exoplanet atmospheres

Young, hot, Earth-sized planet HD 63433d sits close to its star in the constellation Ursa Major, while two neighboring, mini-Neptune-sized planets — identified in 2020 — orbit farther out.

Study sheds new light on strange lava worlds

This artistic representation of the TRAPPIST-1 red dwarf star showcases its very active nature. The star appears to have many stellar spots (colder regions of its surface, similar to sunspots) and flares. The exoplanet TRAPPIST-1 b, the closest planet to the system’s central star, can be seen in the foreground with no apparent atmosphere. The exoplanet TRAPPIST-1 g, one of the planets in the system’s habitable zone, can be seen in the background to the right of the star. The TRAPPIST-1 system contains seven Earth-sized exoplanets.
