Physicists like me don't fully understand what makes up about 83% of the matter of the universe—something we call "dark matter." But with a tank full of xenon buried nearly a mile under South Dakota, we might one day be ...
Physicists believe most of the matter in the universe is made up of an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see.
In celebration of Halloween, Hubble brings you this inky image of the galaxy cluster Abell 611, located over 1000 megaparsecs, or roughly 3.2 billion light years, from Earth. Like all galaxy clusters, the continued existence ...
Physicists searching—unsuccessfully—for today's most favored candidate for dark matter, the axion, have been looking in the wrong place, according to a new supercomputer simulation of how axions were produced shortly ...
Since the 1980s, researchers have been running experiments in search of particles that make up dark matter, an invisible substance that permeates our galaxy and universe. Coined dark matter because it gives off no light, ...
The field of astronomy has been revolutionized, thanks to the first-ever detection of gravitational waves (GWs). Since the initial detection was made in February of 2016 by scientists at the Laser Interferometer Gravitational-wave ...
Almost 20 years ago, the DAMA/LIBRA experiment at Italy's Gran Sasso National Laboratory—LNGS began publishing data showing that it had detected a signal modulation produced by an interaction with the Milky Way's dark ...
Astrophysical evidence suggests that the universe contains a large amount of non-luminous dark matter, but no definite signal has been observed despite concerted efforts by many experimental groups. One exception is the long-debated ...
Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much ...
For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe's mysterious dark matter might consist of a plenitude of black holes sprinkled ...
