An interest in understanding the role that the Milky Way played in Egyptian culture and religion has led University of Portsmouth Associate Professor of Astrophysics, Dr. Or Graur to uncover what he thinks may be the ancient ...
The detection of dark matter, an elusive form of matter believed to account for most of the universe's mass, remains a long-standing goal within the physics research community. As this type of matter can only emit, reflect ...
Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a quintillion (1018) times brighter than the sun. Since they were first detected in 1967 by the Vela ...
Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. This ultra-diffuse galaxy is located on the outskirts of the Fornax Cluster, ...
New research has revealed that the cosmological model developed by Nicolaus Copernicus, the renowned European Renaissance polymath, bears striking resemblance to the one designed by an Arab Muslim astronomer nearly two centuries ...
Astronomers tallying up all the normal matter—stars, galaxies and gas—in the universe today have come up embarrassingly short of the total matter produced in the Big Bang 13.6 billion years ago. In fact, more than half of ...
The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal that this degree of asymmetry ...
Researchers from the University of Waterloo have proposed a new method to measure the Hubble constant that could help resolve one of modern cosmology's pressing puzzles: the Hubble tension.
Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a paper in the journal Classical and Quantum Gravity that proposes a universe ...
Every galaxy is thought to form at the center of a dark matter halo—a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity within dark matter halos ...
