What is this weird long radio structure in between two clusters of galaxies?
It's a....bridge! 🌉
In particular, it is the radio bridge connecting two of the most massive clusters in the nearby Universe: Abell 399 and Abell 401.
Huge discovery in 2019, by F.Govoni and collaborators, using LOFAR: https://arxiv.org/abs/1906.07584 #Astrodon#Astronomy
Let me use this new #AstrophysicsFactlet to tell you a bit about this discovery, and why we care so much!
