  • The atmospheric terminator region of WASP-39 b, a hot gas giant exoplanet, is inhomogeneous, despite past assumptions, with the evening terminator being hotter and thus probably clearer, and the morning terminator probably being cloudy and consequently cooler.

  • An energetic process is needed to convert N2 into compounds essential for life. Simulations show that interactions between powerful solar flares and Earth’s magnetic field could have facilitated nitrogen fixation in the early atmosphere.

  • Of the more than 400 known exoplanets, about 70 transit their central star, most in small orbits (with periods of around 1 day, for instance). Here, observations are reported of the transit of CoRoT-9b, which orbits with a period of 95.274 days, on a low eccentricity, around a solar-like star. Its relatively large periastron distance yields a 'temperate' photospheric temperature estimated to be between 250 and 430 K, and its interior composition is inferred to be consistent with those of Jupiter and Saturn.

  • Observations from the JWST show the presence of a spectral absorption feature at 4.05 μm arising from SO2 in the atmosphere of the gas giant exoplanet WASP-39b, which is produced by photochemical processes and verified by numerical models.

  • The abundance of metals in Mercury’s interior is unique among the rocky planets of the Solar System. The characterization of the ‘super-Mercury’ exoplanet presented in this paper will improve our understanding of how Mercury-like planets can form and evolve.

  • Flares from K and M dwarf stars drive change, and sustain an altered atmospheric chemistry, in orbiting rocky planets, according to a suite of three-dimensional climate models. The atmospheres of rocky planets around G dwarfs rapidly return to their pre-flare states, however.

  • The radial velocities of a young star are measured, revealing the presence of a planet of mass about three-quarters that of Jupiter, orbiting its host star very closely, and thus demonstrating that ‘hot Jupiters’ can migrate inwards in less than two million years.
