This chapter dives into the capabilities of the James Webb space telescope in studying exoplanets, highlighting the discovery of K2-18b and its potential liquid ocean. It discusses how the telescope analyzes starlight filtered through exoplanet atmospheres to identify gases, such as the 'big six' elements essential for life, and explores the discovery of Jupiter mass binary objects.
Madeleine Finlay sits down with science correspondent Hannah Devlin to discuss the amazing discoveries the James Webb space telescope has made in the year since it became operational. From planets that rain sand, to distant galaxies, Hannah explains how some of these discoveries could fundamentally change our understanding of the universe.
