Check out GAMA 526784! It's an "ultra-diffuse galaxy" (UDG), which basically means that its stellar populations are spread out over a very large volume. That means that they tend to be quite dim and hard to spot.

UDGs tend to have older stellar populations, and a sizeable contingent of globular clusters. But this one seems to have some blue star-forming regions!

Hubble Views a Galactic Oddity

The ultra-diffuse galaxy GAMA 526784 appears as a tenuous patch of light in this image from the NASA/ESA Hubble Space Telescope.

One of the rather ridiculous things about UDGs and other low surface brightness galaxies (including some dwarf galaxies that I study) is that... they're transparent!!!

This zoomed-in Hubble Space Telescope image reveals a number of spiral galaxies *behind* the GAMA 526784.
