INBOX ASTRONOMY NASA's Hubble Examines Cloud-9, First of New Type of Object Release date: Monday, January 5, 2026 12:15:00 PM Eastern Standard Time Failed galaxy offers window into ‘dark universe’ Although scientists think most of the universe is composed of dark matter, this material does not emit light, making it difficult to detect. Now, NASA’s Hubble Space Telescope is giving us a rare look into this dark universe by uncovering a dark-matter-dominated, failed galaxy that did not form stars. Called Cloud ...Continue Reading
