How the James Webb telescope is ‘set to find strange and bizarre worlds’

After its first full calendar year of operation, astronomers are using the probe to look for life on thousands of newly discovered planets

There is a distant world where quartz crystals float above a searing hot, puffy atmosphere. Vaporised sand grains, not water droplets, form the clouds that fill the sky on Wasp-107b, a planet 1,300 light years from Earth.

Then there is GJ1214, the sauna planet. With a mass eight times that of Earth, it orbits its parent star at a distance that is one-seventieth of the gap between Earth and the sun and seems to be coated in a thick dense atmosphere containing vast amounts of steam.
