Citizen scientists have uncovered three colossal radio rings, including the brightest and most distant Odd Radio Circle ever seen, revealing new clues about how galactic jets, winds, and cosmic environments shape the universe on breathtaking scales....

team of astronomers has identified a supermassive black hole roaming roughly 30,000 light‑years from the heart of its host galaxy—​the first dormant black hole discovered at such a distance. The object was revealed only after it ripped apart an...

hole could account for the galaxy’s peculiar signature. Because the Saguaro lies at a comparatively modest redshift, its host galaxy can be resolved in high‑resolution images—a feat impossible for most distant red dots, whose surrounding stars and gas...

Holes Sculpt The Cosmos The ultrafast wind in GC 3783 offers a rare glimpse of supermassive black hole in the act of its host galaxy. A briefening soft X rays, likely powered by magnetic reconnection, not just light up the region near the event horizon....

“green” systems, the intense gravitational influence of supermassive black holes can shape the development of their host galaxy. Chandra measurements show the energy distribution of Source 1 (blue) and Source 2 (orange), alongside their respective...

The ’Red Potato’ galaxy shows how a supermassive black hole can quench star formation in the early universe. Astronomers have captured an unusually clear view of how a supermassive black hole can throttle the birth of stars in a galaxy that existed...

Scientists have built a virtual sky with 3.4 billion galaxies, allowing the Euclid mission to test its tools for probing dark matter and dark energy before real data arrives. Euclid’s Flagship mock is a single, gigantic simulated sky that turns...

Central Disk Formation The observed nuclear disk appears to be linked to a pronounced stellar bar extending across the host galaxy. In modern spiral galaxies, such bars act as conduits, channeling gas and stars inward and fostering the development of...

JWST uncovers hidden structures in nearby galaxy Centaurus A, giving a fresh look at the cosmic collision that drives its evolution. Infrared observations from NASA’s James Webb Space Telescope have pierced the veil of dust that cloaks the nearby...

a black hole. However, this specific burst baffled researchers because, once the initial brilliant afterglow faded, no host galaxy could be identified at the coordinates of the explosion. Without a visible host to provide a distance, astronomers were...

NASA’s new image of Centaurus A shows a nearby galaxy sculpted by intense star formation and powerful cosmic forces. NASA has unveiled a high‑resolution composite of Centaurus A, one of the nearest active galaxies, revealing a tangled tapestry of...

Astronomers have discovered a forgotten population of nearly invisible galaxies hiding in the deep darkness of space using powerful telescope observations. Astronomers have uncovered 47 previously unknown dwarf galaxy candidates orbiting three major...
