Using Hubble, astronomers have confirmed the first starless, hydrogen‑rich object dominated by dark matter—nicknamed 'Cloud‑9' and identified as a RELHIC—a relic of early galaxy formation. The finding provides a novel laboratory to probe dark‑matter structures and the baryon physics that suppressed star formation in the young Universe.

Briefing
First confirmed detection of a starless, hydrogen‑rich, dark‑matter‑dominated relic (nicknamed "Cloud‑9", classified as a RELHIC) — provides a direct observational test of dark‑matter halo predictions and the baryonic thresholds for star formation.
The discovery will shape target selection and science cases for future space telescopes; it complements JWST's imaging of a fully formed spiral galaxy 1.5 billion years after the Big Bang and continues Hubble's string of unexpected findings such as the largest planet‑forming disk yet imaged.
