A planet that is about the size of Saturn, but with a temperature more like Earth's, has an atmosphere rich in methane, according to a new study using NASA's James Webb Space Telescope (JWST).

Aerosol dynamics and atmospheric composition modelling encompass the study of airborne particulate matter and reactive gases from their emission through to removal. Key processes include nucleation, ...

The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat successfully launched aboard the SpaceX Falcon 9 rocket at 5:07 a.m. EST on Dec. 21, 2021 from Launch Complex 39A at NASA’s Kennedy Space ...

Methane is common on the cold giants of our solar system, but it has been missing from one important middle ground: giant ...

The Earth’s atmosphere is a dynamic blend of uniform gases—primarily N₂ and O₂—and variable constituents including water vapour, CO₂, CH₄ and trace species such as O₃. These components undergo a web ...

Researchers using NASA's James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system. Observations of the ultra-hot super-Earth TOI ...

Every gas giant astronomers have ever studied shares a basic recipe: a thick envelope of hydrogen and helium, with heavier ...

"We measured the thermal emissions from this rocky planet, and the measurement indicates that the planet has a substantial atmosphere. It is very exciting." When you purchase through links on our site ...

The atmosphere is a layer of gas and suspended solids extending from the Earth's surface up many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's ...

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all. The object, called ...
