The new super space telescope makes unprecedented observations of a far-off planet's atmosphere.
VHS 1256b was first identified by the UK-developed Vista telescope in Chile in 2015.
Earlier observations of VHS 1256b showed it to be red-looking, hinting that it might have dust in its atmosphere. The Webb study confirms it. "There are probably multiple layers of silicate grains. The ones that we're seeing are some of the very, very fine grains that are higher up in the atmosphere, but there may be bigger grains deeper down in the atmosphere."
They didn't take pretty pictures of the planet, at least not in this instance. What they did was tease apart the light coming from VHS 1256b into its component colours as a way to discern the composition of the atmosphere.
