Guest: The closest look into the largest nearby cosmic structures: a foray into the Fornax galaxy cluster
Galaxy clusters are collections of galaxies that are bound together by gravity. They are the largest structures that exist in our Universe, and their mass is dominated by the hot gas that lies between galaxies called the intracluster medium. One of the closest galaxy clusters is Fornax, and it was recently studied in detail using the MeerKAT radio telescope in South Africa. This bite dives deep into a study of the magnetic field of this cluster and the implications the results have of our understanding of clusters of galaxies.
FIREstorms in early galaxies: Simulating the brief, blazing lives of giant clumps
What do a galaxy’s stellar clumps tell us about how it formed? Today’s guest author Michelle Park explores interesting properties of clumps from the FIRE simulations.
Guest: Teaching Machines to Spot Star‑Forming Clumps in Galaxies
Clumpy galaxies dominate the early universe, yet their local counterparts are hard to find. A new machine‑learning approach learns to spot these hidden clumps and opens the door to studying them in far greater detail.
I spy with my large binocular eyes: a dusty torus around a supermassive black hole?
There’s no sugar on this doughnut – might we need to ditch tori for large nuclear disks around active galactic nuclei? Today’s authors peer deep into NGC 4151 to find out!
Hiding in the Shadows: The KM3NeT Search for the Sun and Moon
It’s looking a little (cosmic) rainy today! And the KM3NeT collaboration make the most of the muon downpour, testing for the presence of some familiar celestial bodies in their data.

Ten Ways to Improve Support Resources for Workplace Incivility in Astronomy
Many astronomers unfortunately still experience bullying, harassment, racism, and other incivilities in their careers. It can be hard to find support in these situations, but today’s guest author, Floor Broekgaarden, offers ten suggestions for improvement.
