A spiral galaxy that doesn’t play by the rules
Galaxies in the middle of clusters are usually huge, elliptical galaxies. So what is this spiral-shaped imposter doing here?

What kills the most massive disk galaxies in the Universe? Their own bulge, a sneaky bar, or a giant black hole? Let’s find out!
Most galaxies are either star-forming disks, or red, dead spheroids. But, have galaxy clusters now shown that this divide isn’t quite so clear?
Today’s undergraduate research post features a student who observed long and short period comets to understand the differences in their formation.
This paper reports the results of a cosmological simulation, and how smooth accretion and mergers affect three important aspects of galaxy formation: stellar mass growth, size increase, and morphology changes.
The first geometric evidence of mass dependent redshift evolution of galaxies and the preference for stars to form in discs.
