New observations from the James Webb Space Telescope have given us direct confirmation that some alien worlds have clouds of rock.
The telescope has directly detected silicate clouds in the atmosphere of a brown dwarf – the first time, according to an international team of astronomers, that such a detection has been made in a planetary-mass companion outside the Solar System.
The complete findings, the team says, constitute the best spectrum yet for a planetary mass-object. These results could not only help us better understand these so-called ‘failed stars’, but represent just a foretaste of what the JWST can do.
