UrduAstronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide, findings that UW–Madison astronomer Thomas Beatty presented in Madison today at the 244th meeting of the American Astronomical Society and that he will soon publish in Astrophysical Journal Letters with co-authors from Arizona State University, the University of Arizona, NASA’s Ames Research Center and other organizations.

Jurassic worlds might be easier to spot than modern Earth
A Cornell analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.
Atmosphere – a ghost by the world of glass rains
Russian scientists have modelled atmosphere of the well-known “hot Jupiter” HD 189733b and found out what hindered from stable finding of hydrogen in the atmosphere of the planet. They also defined physico-chemical properties of this planetary system.
A scorching-hot exoplanet scrutinized by UdeM astronomers
Through the Gemini-North Telescope in Hawai’i, the chemical composition of WASP-76 b is revealed in unprecedented detail, giving new insights also into the composition of giant planets.
New from JWST: An Exoplanet Atmosphere as Never Seen Before
New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet — sulfur dioxide — among other details.
Superflares may be less harmful to exoplanets than previously thought, study shows
Astronomers have long suspected that superflares, extreme radiation bursts from stars, can cause lasting damage to the atmospheres — and thus habitability — of exoplanets. A new study published in the Monthly Notices of the Royal Astronomical Society reports that they pose only a limited danger to planetary systems.
