NASA's James Webb Space Telescope May Have Just Unraveled a Longstanding Black Hole Mystery
53+ min ago (560+ words) James Webb Space Telescope (JWST) observations have astronomers on the brink of solving another long-standing astronomical mystery: how do supermassive black holes feed? Astronomers from the Université de Montréal led an international team in the new research, reported in a…...
The nuclear disk changes our understanding of galactic evolution
2+ hour, 21+ min ago (521+ words) In the center of a distant galaxy, a dense disk of young stars has been spotted, rotating and continuing to grow. The light from this structure traveled to Earth for more than 9 billion years, so we are looking at the…...
New findings revise the Milky Way-Andromeda collision odds into a cosmic coin toss
1+ hour, 9+ min ago (1058+ words) For decades, astronomers have predicted that the Milky Way will eventually collide with its nearest large galactic neighbor, Andromeda. (CREDIT: NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger) The Milky Way and Andromeda have appeared locked on…...
Dark matter resides in a hidden extra dimension along with a force-carrying particle known as the “dark photon”, according to a new theory
2+ hour, 58+ min ago (276+ words) Researchers at the University of Sheffield propose a theoretical framework that links the geometry of extra dimensions with the behavior of dark matter, eliminating the need for artificial adjustments in physical models Dark matter, that mysterious substance that holds galaxies…...
If dark matter is everywhere, why do some galaxies seem to contain none at all?
3+ hour, 57+ min ago (868+ words) What does it mean to find a galaxy without dark matter, or with very little of it? Next time you're looking at an amazing image of space showing a cosmos peppered with stars and galaxies – like the images captured by…...
Earliest Galaxy-Building Signs Discovered By Astronomers
4+ hour, 26+ min ago (339+ words) Astronomers from our Physics Department have discovered the earliest known evidence of a galaxy being shaped from the inside out, revealing that key processes in galaxy evolution were already under way when the Universe was still young. The research shows…...
Fifth dimension could explain dark matter
4+ hour, 10+ min ago (166+ words) Wednesday, July 15 2026, 02:20 PM The mysterious substance that binds galaxies together could naturally be ‘in tune’ with a hidden fifth dimension, according to a new University of Sheffield theory aiming to shed light on one of science’s biggest enigmas: dark matter....
NASA’s Roman Space Telescope may finally reveal how the universe's first black holes formed
1+ hour, 20+ min ago (556+ words) starlust.org NASA’s Roman Space Telescope may finally reveal how the universe's first black holes formed NASA's Nancy Grace Roman Space Telescope, set to launch on August 30, 2026, could detect black holes as far back as 11 billion years, according to new…...
The universe is supposed to have no preferred direction or special axis — yet the oldest light ever mapped contains two enormous patterns aligned with each other and strangely tied to the geometry of our own solar system, with some estimates putting the odds below 0.3% by chance
6+ hour, 30+ min ago (474+ words) The cosmic microwave background is supposed to be directionless in the statistical sense. Published July 15, 2026 Under the standard cosmological model, the quadrupole and octopole arise from random primordial fluctuations. Their orientations should therefore be unrelated. There is no reason for…...
Astronomers just found four hidden white dwarf stars near Earth
6+ hour, 30+ min ago (620+ words) Astronomers have directly confirmed four previously hidden white dwarf stars in nearby binary systems. Every system lies within 65 light-years of Earth, and one contains the ninth closest known white dwarf to the Sun. The discoveries were made by researchers at…...
