Webb Study Reveals Rocky Planets Can Form in Extreme Environments

An international team of astronomers has used NASA’s James Webb Space Telescope to provide the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our galaxy.

Discovery Alert: Watch the Synchronized Dance of a 6-Planet System

Six “sub-Neptune” exoplanets orbit their star in a kind of rhythmic dance – one easily set to music.

NASA’s Hubble Measures the Size of the Nearest Transiting Earth-Sized Planet

NASA’s Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighboring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have. The diminutive planet, LTT 1445Ac, was first discovered by […]

NASA Data Reveals Possible Reason Some Exoplanets Are Shrinking

A new study could explain the ‘missing’ exoplanets between super-Earths and sub-Neptunes. Some exoplanets seem to be losing their atmospheres and shrinking. In a new study using NASA’s retired Kepler Space Telescope, astronomers find evidence of a possible cause: The cores of these planets are pushing away their atmospheres from the inside out.

Construction on NASA Mission to Map 450 Million Galaxies Is Under Way

Key elements are coming together for NASA’s SPHEREx mission, a space telescope that will create a map of the universe like none before. NASA’s SPHEREx space telescope is beginning to look much like it will when it arrives in Earth orbit and starts mapping the entire sky. Short for Specto-Photometer for the History of the […]

Scorching, Seven-Planet System Revealed by New Kepler Exoplanet List

A system of seven sweltering planets has been revealed by continued study of data from NASA’s retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any of our immediate neighbors, all seven planets in this system, named […]

Why NASA’s Roman Mission Will Study Milky Way’s Flickering Lights

NASA’s Nancy Grace Roman Space Telescope will provide one of the deepest-ever views into the heart of our Milky Way galaxy. The mission will monitor hundreds of millions of stars in search of tell-tale flickers that betray the presence of planets, distant stars, small icy objects that haunt the outskirts of our solar system, isolated […]

Webb Detects Tiny Quartz Crystals in the Clouds of a Hot Gas Giant

Researchers using NASA’s James Webb Space Telescope have detected evidence for quartz nanocrystals in the high-altitude clouds of WASP-17 b, a hot Jupiter exoplanet 1,300 light-years from Earth.
