The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disc encircling a large exoplanet. The carbon-rich disc surrounding the world called CT Cha B, which is located 625 light years away from Earth, is a possible construction yard for moons, although no moons are detected in the Webb data. The disc offers insight into how the moons of Solar System gas giants like Jupiter might have formed.

Gathering datasets about our soil, from the ground, the air and from space, is part of the robust preparation for these two new European satellites set to extend the capabilities of the Copernicus family of Sentinel missions.
