Astronomers study origin of elusive ultradiffuse galaxies
RIVERSIDE – (INT) – The universe holds a bounty of mysteries and the latest are UDG’s, or ultradiffuse galaxies.

UC Riverside astronomer Laura Sales is leading an international team of ‘star gazers’ it hopes to determine why UDG’s don’t form stars.

“What we have detected is at odds with theories of galaxy formation,” Sales wrote in the latest issue of Nature Astronomy.
