ALMA 📡 has discovered the largest cloud of ejected material ever found around a supergiant star, at an enormous 1.4 light years across! 

Yet how and why this happened is still a mystery 🤔

Galaxy Quenching In the midst of unthinkable grief, an unthinkable discovery.

I am honored to be on this week’s episode of Radiolab! The host @lutimestwo.bsky.social gets excited about galaxies with me! We talk about finding light in the darkest places, both for my research and my life. Lulu was so kind talking about my personal life and so intelligent discussing my research.

When I joined the Europa Clipper project in 2018, I took one look at an early drawing and was immediately suspicious about flying long, flexible radar antennas on the edges of these enormous solar arrays (the biggest flown on any uncrewed spacecraft). This is not conventional. But we made it work!
