Webb May Have Found the Family Tree of the Little Red Dots — Curiosmos
4+ hour, 34+ min ago (878+ words) What happens to Webb’s mysterious little red dots as the universe ages? The Saguaro galaxy’s red nucleus offers a way to explore their hidden surroundings. When the James Webb Space Telescope began finding tiny, intensely red sources in the early…...
JWST finds Chariklo’s inner ring growing denser while its outer ring fades
1+ day, 1+ hour ago (429+ words) Chariklo’s inner ring is getting denser. Its outer ring is fading. Both changes are happening at the same time — and, for the moment, nobody knows why. The finding matters beyond Chariklo itself. Ring systems around planets had already shown that…...
‘Odd couple’ black holes can find each other in space
3+ day, 9+ hour ago (477+ words) When two black holes find each other in the vastness of space, they can form a binary odd couple—and it’s more common than researchers expected. Scientists think most black holes are born when a star dies and its core…...
Hubble and Webb Teamed Up on Distant Solar System Bodies and Found Fewer Tiny Ones Than Some Models Predicted
3+ day, 19+ hour ago (840+ words) NASA announced the joint Hubble and Webb results on September 8, alongside two complementary papers published that day in The Astronomical Journal. NASA says it is the first time the two telescopes have been used jointly to study Trans-Neptunian Objects, and…...
NASA found a strange cosmic object that may explain how black holes become supermassive
3+ day, 23+ hour ago (900+ words) Little red dots should shine in X-rays if black holes power them. None did, until Chandra found one 11.8 billion light-years away that does. Astronomers have found a single object in the constellation Ursa Major that behaves like nothing else in…...
Astronomers Discover Chaotic Formation of Massive Binary Star System Using ALMA Telescope

Solving the long-standing problem of black hole equilibrium.
4+ day, 12+ hour ago (373+ words) Using mathematical analysis of Einstein's equations, the research team proved the answer is no. When there are two or more black holes in such a configuration, the interaction forces between them cannot completely cancel each other out, and a static…...
Standard stellar-evolution models predict few black holes born directly between about 60 and 130 solar masses, yet GW231123 appeared to involve objects of roughly 137 and 103 solar masses. A new analysis argues that gravitational lensing magnified and distorted the signal, making the merger appear closer—and therefore intrinsically heavier—than it was. Under this still-unconfirmed interpretation, its combined mass falls from 190–265 to 100–180 Suns, making the system far less extreme.
4+ day, 12+ hour ago (861+ words) A peer-reviewed lensing analysis could reduce GW231123’s inferred total mass from 190–265 to 100–180 solar masses. The signal is a compelling candidate, but gravitational-wave lensing remains unconfirmed....
This 'impossible' black hole merger may be explained by a warp in spacetime
4+ day, 15+ hour ago (437+ words) "Like light, gravitational waves can also be deflected, magnified, and split into multiple signals by massive objects." A "forbidden" merger between two massive black holes may not have been quite as impossible as previously thought. That's according to new research…...
