Summary:
- The Hubble Space Telescope has discovered a unique and rare object called "Cloud 9," which is a failed galaxy that is unlike anything seen before.
- Cloud 9 is a dark, diffuse, and irregularly shaped object that is located in a galaxy cluster about 230 million light-years from Earth.
- Astronomers believe that Cloud 9 may have formed from the gravitational collapse of a large cloud of gas and dust, but it failed to develop into a full-fledged galaxy due to a lack of sufficient mass and star formation.
