A long-standing issue in astrobiology is whether planets orbiting the most abundant type of stars, M-dwarfs, can support liquid water and eventually life. A new study shows that subglacial melting may provide an answer, significantly extending the habita
extrasolar planet WASP-96b spectrumSpectrum of extrasolar planet WASP-96b taken by the James Webb Space Telescope when the planet transited its star. The spectrum shows the distinct signature of water, along with evidence for clouds and haze. WASP-96b is about 1,150 light-years from Earth and...
unobserved population of planetesimals. Promising progress is being currently made to observe the gas component as well, using millimetre and sub-millimetre giant radio interferometers. Within planetary systems themselves, individual planets are the assembly of a solid body and a fluid envelope, ...
