Interpretation of the ongoing efforts to simulate the atmospheres of potentially-habitable terrestrial exoplanets requires that we understand the underlying dynamics and chemistry of such objects to a much greater degree […]
A international team of astronomers led by Université de Montréal has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising “super-Earth” covered in […]
LHS 1140 b is the second-closest temperate transiting planet to the Earth with an equilibrium temperature low enough to support surface liquid water.
NASA announced Friday it selected three industry proposals to help develop technologies for future large space telescopes and plan for the agency’s Habitable Worlds Observatory mission concept, which could be […]
The Habitable Worlds Observatory (HWO) is NASA’s next astrophysics flagship mission concept recommended by the 2020 Decadal Survey on Astronomy and Astrophysics.
Small rocky planets, as well as larger planets that suffered extensive volatile loss, tend to be drier and have thinner atmospheres as compared to Earth. Such planets probably outnumber worlds […]

Understanding how giant and terrestrial planets form and evolve, what is their internal structure and that of their atmosphere, represents one of the major challenges of modern astronomy, which is […]
The Closeby Habitable Exoplanet Survey (CHES) is dedicated to the astrometric exploration for habitable-zone Earth-like planets orbiting solar-type stars in close proximity, achieving unprecedented micro-arcsecond precision.
JWST has created a new era of terrestrial exoplanet atmospheric characterization, and with it the possibility to detect potential biosignature gases like CH4.
What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA’s James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A […]
