Hubble Dark Galaxy, Feb 23, 2026 · Using the Hubble Space Telescope in combination with other observatories, astronomers identified an unusually dim galaxy, known as candidate dark galaxy-2, that appears to be almost entirely dominated by dark matter. 1 day ago · Hubble can't directly see dark matter, but its infrared and visible-light observations can detect dark matter's gravitational lensing effects on the normal matter Hubble observes. May 5, 2026 · The Hubble Space Telescope is part of NASA's fleet of "Great Observatories," which also includes the James Webb Space Telescope and Chandra X-ray Observatory. Cosmic magnifying glass: Hubble’s image of MACS0329-0211 shows how the cluster’s gravity bends light from galaxies billions of light-years away. Feb 21, 2026 · Astronomers have uncovered one of the most mysterious galaxies ever found — a dim, ghostly object called CDG-2 that is almost entirely made of dark matter. 6 days ago · Hubble’s latest image of galaxy cluster MACS0329-0211 reveals a powerful gravitational lens that is magnifying some of the most distant galaxies ever observed. Since its 1990 launch, Hubble has changed our fundamental understanding of the universe. Rare gravitational arcs: Faint arcs and a May 5, 2026 · The Hubble Space Telescope is part of NASA's fleet of "Great Observatories," which also includes the James Webb Space Telescope and Chandra X-ray Observatory. You can also explore Hubble's archive of older image and science releases. Mar 23, 2026 · 5 January 2026: A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical object —a starless, gas-rich, dark-matter cloud that is considered a “relic” or remnant of early galaxy formation. Feb 18, 2026 · Employing NASA/ESA Hubble Space Telescope in combination with ESA Euclid and ground-based NAOJ Subaru Telescope, astronomers identified a galaxy that appears to be almost entirely dominated by dark matter with only a smattering of stars. Feb 19, 2026 · Using the Hubble Space Telescope along with the Euclid Space Telescope, astronomers have discovered what seems to be one of the most heavily dark-matter-dominated galaxies ever seen. Feb 18, 2026 · NASA's Hubble Space Telescope has revealed an exceptional discovery in the Perseus galaxy cluster: CDG-2, an ultra-low surface brightness galaxy composed of 99% dark matter. Both dark matter and dark energy pose deep, unanswered questions about the universe. Nicknamed “Cloud-9,” this is the first confirmed detection of such an object in the Universe. Apr 21, 2026 · Dark energy isn't concentrated in galaxies or galaxy clusters, instead scientists think it’s spread throughout the universe. Jan 16, 2026 · Hubble's latest discoveries and its most recent images. Rare gravitational arcs: Faint arcs and a . This "dark Feb 18, 2026 · Astronomers, using the NASA/ESA Hubble Space Telescope in combination with other observatories, identified a galaxy that appears to be almost entirely dominated by dark matter with only a smattering of stars. Feb 18, 2026 · Hubble identified a rare dark galaxy — a low-surface-brightness galaxy dominated by dark matter and containing only a sparse scattering of faint stars.
