It’s been a busy month for Cardiff astronomers (and their colleagues). From gravity’s role in star formation to molecules found in a supernovae explosion, and from debris around neutron stars to organic molecules emitted from one of Saturn’s moons, there’s a lot to talk about. I took the opportunity to chat to Emily Drabek-Maunder, Mikako Matsuura and Gwen Williams about their work.

As usual, Edward Gomez and I also talk about stories from around the world. Astronomers from the US travelled to Argentina to witness the occultation of 2014 MU69 – the next icy world to be visited by the New Horizons spacecraft. Finally, July saw the end of the very successful LISA Pathfinder mission.
