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?

Before giant galaxies, it was all slugs, mammoths, and big nebulous blobs of emission: find out why in today’s astrobite!
Today’s bite explores the two main pathways of S0 galaxy formation, ram-pressure stripping and galaxy mergers.
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?
Most galaxies take significant fractions of the age of the universe to noticeably change. Others transform themselves in the first two billion years of the universe. How does this happen?
Major galaxy mergers are thought to be one of the main ways of producing massive elliptical galaxies. Surprisingly though, some of the most massive galaxies in the local universe have gas disks. Here’s how they might be made.
