Astronomers using NASA's Hubble Space Telescope discovered a cosmic object called Cloud-9, described as a failed galaxy located 14 million light-years from Earth. The object is a cloud of dark matter that contains no stars, marking the first confirmed detection of such an object.

Cloud-9 is scientifically known as a Reionization-Limited H I Cloud, or RELHIC, where H I refers to neutral hydrogen. Scientists believe it represents a primordial building block of a galaxy that never fully formed stars, preserving conditions from the universe's earliest eras.

The object's core consists of neutral hydrogen spanning approximately 4,900 light-years across, with gas mass estimated at roughly one million times that of the Sun. Calculations indicate the entire structure contains approximately five billion solar masses of dark matter.

Cloud-9 was first identified in 2023 during a radio survey by China's Five-hundred-meter Aperture Spherical Telescope, with follow-up observations from the Green Bank Telescope and Very Large Array. Hubble's Advanced Camera for Surveys confirmed the absence of stars within the cloud.

The discovery provides scientists a rare opportunity to study a dark matter-dominated cloud without light interference from stars. Andrew Fox noted that Cloud-9 serves as "a window into the dark universe," helping researchers understand the invisible material comprising most cosmic mass.

Cloud-9 appears physically associated with the nearby spiral galaxy Messier 94, with high-resolution radio data suggesting subtle gravitational interaction. The object exists in a narrow mass range where it can persist without collapsing to form stars or dispersing its gas entirely.
