Scientists at NASA have identified a rare cosmic object called Cloud 9, marking the first confirmed example of a failed galaxy dominated by dark matter and completely lacking stars.
Cloud 9 is a dark, gas-rich structure classified as a Reionization-Limited H I Cloud, a long-theorised remnant from the universe’s earliest galaxy formation period, now finally confirmed through direct observation.

Located around 14 million light-years from Earth near the spiral galaxy Messier 94, the object holds vast hydrogen reserves yet shows no signs of star formation.
Although radio telescopes including the Very Large Array first detected the cloud, only the Hubble Space Telescope confirmed its complete absence of stars.
Lead researcher Alejandro Benitez-Llambay explained that Cloud 9’s mass allows long-term survival, yet remains insufficient to trigger star birth, validating predictions about failed galaxies.

Researchers say such objects formed shortly after the Big Bang, when intense radiation blocked star formation, making Cloud 9 a rare survivor from an era most similar relics failed to endure.
