Dark dwarfs are hypothetical dark matter-powered objects that formed from the cooling of brown dwarfs, according to a team of astronomers from Durham University,...
A new study by University of California, San Diego computational astrophysicist Ethan Nadler shows that star formation can occur in halos down to 10 million...
2MASX J23453268-0449256 (J2345-0449 for short), an extremely massive, rapidly rotating, jet-launching spiral galaxy approximately 947 million light-years...
A core-collapsing self-interacting dark matter subhalo is responsible for the peculiar spur and gap features observed in GD-1, a stellar stream within...
Dark energy — an unknown energy source that is causing our Universe’s expansion to accelerate – doesn’t actually exist, according to new research.
This...
Using a catalog of 26,041 white dwarfs observed by the Sloan Digital Sky Survey, astronomers have confirmed a long-predicted effect in these ancient ultradense...
The standard model predicted that the NASA/ESA/CSA James Webb Space Telescope would see dim signals from small, primitive galaxies. But data are not confirming...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
The two galaxy clusters, known collectivity as MACS J0018.5+1626, each contain thousands of galaxies and are located billions of light-years away from...
New calculations reveal that pairs of supermassive black holes can merge into a larger black hole because of previously overlooked behavior of dark matter...
The satellite galaxy Crater II (or Crater 2) of the Milky Way is located approximately 380,000 light-years away from Earth in the constellation of Crater....
New research led by the University of California, Irvine addresses a fundamental debate in astrophysics: Does invisible dark matter need to exist to explain...
A team of particle physicists from the University of Melbourne, the Australian National University, King’s College London and Fermi National Accelerator...
Ursa Major III/UNIONS 1 (UMa3/U1 for short) is the least luminous and lowest-mass Milky Way satellite ever discovered, and possibly one of the most dark...
University of Ottawa’s Professor Rajendra Gupta challenges the current theoretical model for the composition of the Universe by showing that, in fact,...
The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics...
Mothra is a system of two supergiant stars in one of the extremely magnified galaxies behind the lensing galaxy cluster MACS J0416.1-2403.
Mothra is best...
