Hubble Dark Galaxy, Cosmic magnifying glass: Hubble’s image of MACS0329-0211 shows how the cluster’s gravity bends light from galaxies billions of light-years away. Apr 21, 2026 · Dark energy isn't concentrated in galaxies or galaxy clusters, instead scientists think it’s spread throughout the universe. Since its 1990 launch, Hubble has changed our fundamental understanding of the universe. 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. 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. 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 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. Both dark matter and dark energy pose deep, unanswered questions about the universe. 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. 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. a9, v1k, ehsusw, ang, 9sfawew, wm, bhqr, lhglv, vlp, 9cdx,
