For the first time, a team at Leiden University led by Ewine van Dishoek, an external scientific member of MPE, has robustly detected semi-heavy water ice around a young, sun-like star. These results support the theory that some of the water in our solar system originated before the Sun and its planets formed. The researchers used the James Webb Space Telescope to make their discovery, which they have published in The Astrophysical Journal Letters.
