The very ancient super-Earth TOI-561 b must have a thick atmosphere, data from the JWST indicates, or its day side would be ...

Satellite reentry can release nitrogen oxides and alumina, impacting the ozone layer and stratosphere. Alternatives like Design for Non-Demise and controlled reentry aim to reduce environmental and ...

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

An ancient rocky world so close to its star that its surface is largely molten should have been stripped bare of gas long ago ...

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

Astronomers have discovered a carbon-rich exoplanet with a bizarre atmosphere and shape, orbiting a neutron star under extreme conditions that challenge current models of planetary formation. Scientis ...

“This system is unique because we are able to view the planet illuminated by its host star, but not see the host star at all, ...

Astronomers are scratching their heads at the odd chemistry, which hints at soot clouds and possibly diamond formation deep inside.

In one study, these particles from high-altitude wildfire smoke created a dramatic cooling effect not accounted for in current climate models.

Pulsars emit a lot of radiation, in particular high-energy gamma-rays and radio waves pulses. That light is invisible to JWST, which studies the universe in infrared, but it affects the planet’s ...
