Although researchers have been studying dark matter and trying to observe it, its nature is a longstanding scientific mystery. The standard cosmological model suggests that approximately one-quarter of cosmological energy ...
A team of researchers in the Republic of Korea, the U.S., Brazil, Indonesia and the U.K. have recently carried out a direct search for inelastic boosted dark matter (IBDM) using a terrestrial detector. Their study, published ...
In giant clusters of hundreds or thousands of galaxies, innumerable stars wander among the galaxies like lost souls, emitting a ghostly haze of light. These stars are not gravitationally tied to any one galaxy in a cluster.

An international team of astronomers reports the discovery of a new ultra-faint dwarf galaxy as part of the DECam Local Volume Exploration (DELVE) survey. The newly found galaxy, designated Pegasus IV, has an absolute magnitude ...
Gazing into the universe is like looking into a funhouse mirror. That's because gravity warps the fabric of space, creating optical illusions.

Using the Hubble Space Telescope (HST), astronomers have detected three new ultra-faint dwarf galaxies associated with the nearby spiral galaxy NGC 253. The newly found dwarfs turn out to be among the faintest systems so ...
(Phys.org)—It was another good week for physics as Ian Shoemaker, until recently with the University of Southern Denmark, proposed a new theory, suggesting that if we want to detect dark matter, we might need a different ...
A team of astronomers from the University of Cambridge have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. The findings, from newly-released imaging data taken from ...
