Hubble Space Telescope studies peculiar ‘ultra-diffuse galaxy’ (photo)

A ‘wispy’ galaxy 4 billion light-years away from us features in a glorious new photo from the Hubble Space Telescope.

Called GAMA 526784, the galaxy represents one of a set of “ultra-diffuse” galaxies that are puzzling astronomers. These galaxies are ghostly star collections with low luminosity, or inherent brightness. Scientists believe “ultra-diffuse” galaxies are so dim because they don’t contain the gas needed to fuel starbirth. But other questions are harder to answer.
