Summary

In this episode of ‘Dernières Nouvelles des Étoiles’, Hugo Lisoir covers the latest space news. The main story is the first confirmed image of a circumplanetary disk around the young star PDS 70, which could be forming exomoons. The disk, observed with ALMA, is 500 times larger than Saturn’s rings and could form up to three moons the size of Earth’s Moon. The video also reports on the Russian Nauka module’s journey to the ISS, the upcoming Boeing Starliner test flight, Ingenuity’s 10th flight on Mars, and NASA’s decision to use a Falcon Heavy to launch the Europa Clipper mission. The host also mentions the channel’s summer break and upcoming content.
