This April, news reports linked the stinky gas dimethyl sulfide (DMS) in the atmosphere of a distant exoplanet called K2-18b to possible life on it. The reports, prompted by work led by astronomer ...

Only 43 (to date) have been observed directly (about 0.5% of them). Most are discovered through indirect means, such as radial velocity or the transit method. The transit method is where you look at ...

Looking at the atmosphere of an exoplanet is even more difficult. Scientists use spectroscopy to do this ... this study is in a graph fitting light absorption rates to which kind of molecules ...

A team of scientists using the James Webb Space Telescope believe exoplanet K2-18b ... The way they analyzed the planet's atmosphere is called transmission spectroscopy. When planets cross in ...

When starlight passes through a planet's atmosphere, spectroscopy ... clouds or haze in the exoplanet's atmosphere, that can make it difficult to detect molecular absorption lines in the ...

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere.

"Detecting biosignature gases via exoplanet atmosphere transmission spectroscopy is in principle within JWST's reach." The question is, how reliable are those detections? Are public expectations ...

an exoplanet between Earth and Neptune in size, finding evidence that it is a giant rocky planet (super-Earth) surrounded by a thick, hot atmosphere. NASA’s JWST detected gases emanating from a ...
