Exobiology: the colors of icy exoplanets would betray colonies of microbes
The determination of reliable biosignatures that would at least allow us to think that an exoplanet very probably hosts forms of life similar to those known on Earth is not…

Discovery of mini-Neptunes that transform into super-Earths
There are many mini-Neptunes among exoplanets. Planets which, like our Neptune, are essentially composed of hydrogen and helium. Astronomers have just found two of them that are losing their atmosphere…
The atmosphere of this exoplanet has points in common with that of the Earth
The atmosphere of WASP-189b, one of the most extreme planets known, appears to have distinct layers, similar to Earth’s atmosphere, although with very different characteristics. You will also be interested…
How will the James-Webb Space Telescope scan other planets?
The James-Webb Space Telescope continues to adjust its instruments to begin its first observations. During its mission, the JWST will notably be able to direct its instruments towards exoplanets and…
