Webb data suggest potential atmosphere around rocky exoplanet
Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.

Volcanic ‘activity’ in black holes blows monumental bubbles of hundreds of thousands of light-years
An international team of researchers observed the full extent of the evolution of hot gas produced by an active black hole for the first time. As it evolves, the hot gas encompasses a much larger area than previously thought and even impacts objects residing at great distances. Their study is published…

Many planetary systems prematurely evaporate into thin air
When stars are born, large clouds of gas and dust form that are known as circumstellar discs. Research by PhD candidate Francisca Concha-Ramírez shows that strong radiation from neighbouring stars soon evaporates the dust in these discs, which can prevent planet formation at an early stage. PhD defence…

Surprise: No methane on the night side of exoplanet WASP-43b
The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…
