NASA Hubble Space Telescope Ultra-Diffuse Galaxy GAMA 526784
The NASA / ESA Hubble Space Telescope recently captured GAMA 526784, a hazy ultra-diffuse galaxy located approximately 4-billion light years from Earth. What sets ultra-diffuse galaxies apart from others is that their dark matter content can be either extremely low or extremely high, with some even being observed with nearly zero dark matter.

One other peculiarity of this class of galaxies is their unusual abundance of bright globular clusters, something that has not yet been seen in other types of galaxies. Hubble used its Advanced Camera for Surveys (ACS), installed in 2002 by astronauts during Hubble Servicing Mission 3B, to capture GAMA 526784. For those interested in galactic oddities, there’s this ghostly face formed by two galaxies colliding with each other.

This image comes from a set of Hubble observations designed to shed light on the properties of ultra-diffuse galaxies. Hubble’s keen vision allowed astronomers to study GAMA 526784 in high resolution at ultraviolet wavelengths, helping to gauge the sizes and ages of the compact star-forming regions studding the galaxy,” according to the ESA.
