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 ...

Do certain exoplanets mirror Earth regarding their distribution of iron and water? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers ...

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 ...

Astronomers know of about 60 rocky exoplanets orbiting in the habitable zones of their stars. When they try to determine how habitable these planets might be, detecting water in their atmospheres ...

"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 ...

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 ...

When astronomers looked toward the planet WASP-121b, they were searching for evidence of an atmosphere. What they didn't expect to see was a stratosphere made up of water so hot, it was glowing. The ...

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon ...

In a zesty new discovery, scientists have unearthed a strange lemon-shaped exoplanet. It is unlike one we have seen before, ...

One of the main questions in exoplanet science concerns M dwarfs (red dwarfs) and the habitability of exoplanets that orbit ...
