radial velocity

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope has directly imaged an extrasolar planet about 12 light-years from Earth. Although there were hints that the planet existed, it was not confirmed until Webb photographed it. The planet is one of the coldest exoplanets observed so far.
