Peering deep into the fluffy atmosphere of WASP-107b, a team of European astronomers discovered not only water vapor and sulfur dioxide, but even silicate sand clouds. (Klaas Verpoest, Johan Van ...

Water has been discovered for the first time in the atmosphere of an exoplanet with Earth-like temperatures that could support life as we know it, scientists revealed Wednesday. Eight times the mass ...

Scientists have discovered the strongest evidence to date for a stratosphere on a planet outside our solar system, or exoplanet. A stratosphere is a layer of atmosphere in which temperature increases ...

"When the Earth's mantle melts, it produces basalts," said Esteban Gazel, professor of engineering. Basalt, a gray-black volcanic rock found throughout the solar system, are key recorders of geologic ...

Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles observations by ground and space telescopes. The ...

In this illustration super-Earth Kepler-138 d is in the foreground. To the left, the planet Kepler-138 c, and in the background the planet Kepler 138 b, seen in silhouette transiting its central star.

As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might ...

An exoplanet orbiting a dwarf star 124 light-years from Earth made headlines around the world in April 2025. Researchers at the University of Cambridge reported that planet K2-18b could be a marine ...

Ocean World: The James Webb Space Telescope (JWST) is providing scientists with a closer look at previously discovered exoplanets. Two teams of researchers have now used the NASA telescope to analyze ...

Researchers from School of Earth and Space Exploration at Arizona State University say there might actually be too much water for the TRAPPIST-1 planets to harbor life. Share on Facebook (opens in a ...

Researchers from MIT and the University of Birmingham (UB) believe that they've cracked the formula for detecting habitable planets using currently available technology. It all has to do with an ...
