Neutron stars are massive objects formed from the collapse of massive supergiant stars, denser than any other stellar object, except for black holes. Most are detected as radio pulsars, but now

also allows to hunt for neutron stars:

was recently struck by a high-speed micrometeoroid and the strongest solar storm in 20 years. But thanks to the hard work of the Gaia teams on Earth, routine operations have been restored.
Last week

was held with a 2-day Gaia symposium: "Gaia: The (TWO) Billion Star Galaxy Census: from the Solar System to our Milky Way and beyond". Interested in the talks of this symposium, slides have been uploaded to the GREAT wiki page here:
Paper day: the dynamical masses across the Hertzsprung-Russell Diagram! This is my favorite plot I have ever made 😍😍 In one sentence, we measure the mass of stars using
@ESAGaia
wide binaries + Newtonian dynamics + stats + a bit neural network 🥳(1/13)

#GaiaDR3
's wide binaries allow to derive the dynamical masses of stars. The mean masses for different stellar groups are highlighted in this visual. More details on this stellar weight scale? 👉🏾

@ESAGaia
reveals that the Milky Way’s last major collision was surprisingly recent!
Gaia unravels our history by studying the wrinkles created by collisions, but there's a catch. Like Benjamin Button, our galaxy is getting less wrinkly over time 👉
