The James Webb Space Telescope detected an atmosphere on a lava-covered exoplanet, evidence that small planets close to stars ...

The James Webb Space Telescope detected an atmosphere rich with carbon and helium, which is unexpected on this hot planet ...

A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our ...

JWST observations of the ultra-hot super-Earth exoplanet TOI-561 b provide the strongest evidence to date for an atmosphere surrounding a rocky planet beyond our Solar System.

Earth TOI-561 b must have a thick atmosphere, data from the JWST indicates, or its day side would be even hotter than it is.

Scientists using the James Webb telescope observed a distant exoplanet with an atmosphere of soot and diamonds, challenging ...

Webb’s latest observations reveal a hellish world cloaked in an unexpected atmosphere: TOI-561 b, an ultra-hot rocky planet racing around its star in under 11 hours. Despite being blasted by intense ...

More than a billion years ago, a shallow basin in what is now northern Ontario held a subtropical lake. The setting likely resembled modern Death Valley, where heat drives evaporation and leaves salt ...

We now have a clearer picture of how the atmosphere cleanses itself of air pollution and harmful gases. With their recent study, an international team headed by scientists from the National Oceanic ...

A recent stellar occultation in 2019 indicated a rapid collapse of Pluto's atmosphere, with pressure decreasing over 20% since 2016, contrasting with previously observed growth since 1988. Pluto's ...

Carbon dioxide makes up only about 0.04% of the Earth’s atmosphere, but that seemingly small figure ignores threat CO2 poses to the climate. Carbon dioxide accounts for 79% of U.S. greenhouse gas ...

Most people think that the Earth's atmosphere stops a bit over 62 miles (100 km) from the surface, but a new study based on observations made over two decades ago by the joint US-European Solar and ...
