The universe is still full of surprises! This is Cloud-9, a starless blob held together by dark matter--a "failed galaxy."

Astronomers have long speculated that such hidden objects formed the building blocks of bright galaxies like our own. Now we've found one.

This image shows the location of Cloud-9, which is 14 million light-years from Earth. The diffuse magenta is radio data from the ground-based Very Large Array (VLA) showing the presence of the cloud. The dashed circle marks the peak of radio emission,which is where researchers focused their search for stars. Follow-up observations by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys found no stars within the cloud. The few objects that appear within its boundaries are background galaxies. Before the Hubble observations, scientists could argue that Cloud-9 is a faint dwarf galaxy whose stars could not be seen with ground-based telescopes due to the lack of sensitivity. Hubble’s Advanced Camera for Surveys shows that, in reality, the failed galaxy contains no stars.
