Astronomers find evidence of liquid recently flowing on the surface of Pluto
3+ hour, 53+ min ago (1152+ words) Pluto’s surface stays at about −393°F (−236°C), cold enough that nitrogen there isn’t a gas at all but a glacier miles deep. Nothing about a world that cold suggests liquid could be flowing on its surface. But dark streaks along…...
Three Supermassive Black Holes Found in a Galaxy From the Dawn of the Universe
5+ hour, 27+ min ago (26+ words) Three supermassive black holes in a distant and therefore very old galaxy offer a glimpse into how black holes merged and grew in the early universe....
More Stars, More Worlds: This Stunning Finding Is Shaking Up Our Universe - Futura-Sciences
8+ hour, 33+ min ago (321+ words) A press release from Leiden University (corresponding to the Nature Astronomy article, freely available via arXiv) breaks it down: galaxies previously believed to be massive early in the story of the observable Universe—which is a headache for the standard…...
Space News: Hubble solves merger mystery from Milky Way’s early years
11+ hour, 20+ min ago (900+ words) Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from NASA’s Hubble Space Telescope shows definitive evidence of a dwarf galaxy merging with the young Milky Way galaxy in…...
Top cosmic mysteries NASA’s powerful new Nancy Grace Roman Space Telescope could solve
11+ hour, 49+ min ago (310+ words) Scientists believe that the expansion of the universe is accelerating instead of slowing down, and dark energy may be the cause of it. Roman’s broad view will collect infrared from a vast area of the sky potentially from a billion…...
JWST revealed a Bizarre DOUBLE-BARRED Spiral Galaxy in Detail: NGC 1365
8+ hour ago (61+ words) The Greatest Barred Spiral Ever: NGC 1365 We picture galaxies as normal, spinning pinwheels with graceful spiral arms or as faint smudges in the dark when viewed from Earth. But this galaxy of choice …...
New Research Explores Why Some Black Hole Flares Fade Over Time
15+ hour, 20+ min ago (315+ words) Home » Science » New Research Explores Why Some Black Hole Flares Fade Over Time These phenomena are known as repeating partial tidal disruption events (rpTDEs). They enable astronomers to repeat observations of the same star interacting with the same black hole,…...
When scientists announced Webb’s first definitive detection of Neptune’s auroras in March 2025, they revealed another surprise: observations taken in 2023 showed that the planet’s upper atmosphere had cooled by several hundred degrees since Voyager 2 visited in 1989—and scientists still don’t know exactly why.
15+ hour, 43+ min ago (1334+ words) Webb's 2023 H3+ spectrum measured Neptune's upper atmosphere at 358 plus or minus 8 kelvin, far below Voyager 2's 1989 estimate, but two snapshots cannot yet explain what drove the change.

The Milky Way Started Eating Other Galaxies Billions of Years Earlier Than We Thought, New Study Says
1+ day, 1+ hour ago (356+ words) Our galactic home, the Milky Way galaxy, was a hungry fella several eons ago. Scientists observing clusters of stars hanging out near the Milky Way’s center found evidence suggesting that our galaxy once collided with and devoured a smaller galaxy…...
JWST finds early galaxies may be 4 times more massive than thought
1+ day, 7+ hour ago (315+ words) Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even…...
