Statistical Analysis Shows an Unexpected Interaction Between Dark Matter and Ordinary Matter

A newly published statistical analysis of mini-spiral galaxies shows an unexpected interaction between dark matter and ordinary matter. The research shows that where the relationship is obvious and cannot be explained in a trivial way within the context of the Standard Model, these objects may serve as “portals” to a completely new form of Physics […]

Dark Matter Smoother than Expected

Using data from the Kilo Degree Survey, a team of astronomers reveal that dark matter in the cosmic web, which accounts for about one-quarter of the content of the Universe, is less clumpy than we previously believed. Analysis of a giant new galaxy survey, made with ESO’s VLT Survey Telescope in Chile, suggests that dark […]

MIT Physicists Seek Dark Matter Particle

Physicists from MIT are proposing a new experiment to detect a dark matter particle called the axion. If successful, the effort could crack one of the most perplexing unsolved mysteries in particle physics, as well as finally yield a glimpse of dark matter. Axions are hypothetical elementary particles that are thought to be among the […]

Mysterious X-Ray Signal Most Likely Originates from Sulfur Ions

New research shows that a recently discovered mysterious X-ray signal most likely originates from sulfur ions, not from dark matter. A mysterious X-ray signal from clusters of galaxies recently caused some excitement among astronomers: Does it perhaps originate from dark matter, which makes up around 80 percent of the matter in the universe, but which […]

Galaxy Dragonfly 44

An international team of astronomers has discovered a massive galaxy that consists almost entirely of dark matter. The galaxy, Dragonfly 44, is located in the nearby Coma constellation and had been overlooked until last year because of its unusual composition: It is a diffuse “blob” about the size of the Milky Way, but with far […]

Astronomers Suggest Possible Link Between Primordial Black Holes and Dark Matter

A newly published study from NASA’s Goddard Space Flight Center suggests a possible link between primordial black holes and dark matter. Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of […]

New Hypervelocity Binary Star Challenges Dark Matter, Stellar Acceleration Models

Astronomers have discovered a hypervelocity binary star that challenges dark matter and stellar acceleration models. A team of astronomers at the Friedrich Alexander University led by Péter Németh has discovered a binary star moving nearly at the escape velocity of our galaxy. There are about two dozen so-called hypervelocity stars known to be escaping the […]

Astronomers Detect the Signature of Dark Matter Annihilation

By studying the spatial distribution of gamma-ray emission in the Milky Way, astronomers believe they have identified a signature of dark matter annihilation. We live in a dramatic epoch of astrophysics. Breakthrough discoveries like exoplanets, gravity waves from merging black holes, or cosmic acceleration seem to arrive every decade, or even more often. But perhaps […]

New Research Pushes Frontier on Galaxy Clusters

Astronomers are using data from NASA’s Chandra X-ray Observatory, the Hubble Space Telescope, and the NSF’s Jansky Very Large Array to learn more about galaxy clusters, including how they grow via collisions. Galaxy clusters are enormous collections of hundreds or even thousands of galaxies and vast reservoirs of hot gas embedded in massive clouds of […]

Hubble Space Telescope Shows the Inner Region of Abell 1689

New research from NASA’s Jet Propulsion Laboratory suggests that the internal structure of a galaxy cluster is linked to the dark matter environment surrounding it. This is the first time that a property besides the mass of a cluster has been shown to be associated with surrounding dark matter. Dark matter is a mysterious cosmic […]

New Results from the Large Underground Xenon Dark Matter Experiment

A new set of calibration techniques employed by LUX scientists has dramatically improved the sensitivity of the LUX Dark Matter Experiment. The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be […]

Galaxy Clusters Shed Light on Dark Matter and Dark Energy

Astronomers hope that by studying the properties of galaxy clusters at different stages in the history of the Universe they can shed light on the dark matter and dark energy. ESO telescopes have provided an international team of astronomers with the gift of the third dimension in a plus-sized hunt for the largest gravitationally bound […]

Dense Dark Matter Hairs Spreading Out from Earth

A new study proposes the existence of long filaments of dark matter, called “hairs,” which are created when a stream of dark matter particles goes through a planet. According to simulations, the hair is densest at a point called the “root.” When particles of a dark matter stream pass through the core of Earth, they […]

Dark Matter Dominates in Nearby Dwarf Galaxy Triangulum II

A new study from the California Institute of Technology reveals that dwarf galaxy Triangulum II has the highest concentration of dark matter in any known galaxy. Dark matter is called “dark” for a good reason. Although they outweigh particles of regular matter by more than a factor of 5, particles of dark matter are elusive. […]

Physicists Use Cold Atoms to Probe Dark Energy

A team of physicists reproduced the low-density conditions of space to precisely measure dark energy, helping to reveal how strongly dark energy interacts with normal matter. Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The […]

New Approach for Detecting Dark Matter

Physicists are working on a new theory to detect dark matter. They believe that dark matter particles annihilate into “dark radiation” when they collide and that they should be able to detect the signals from this radiation. The majority of the mass in the Universe remains unknown. Despite knowing very little about this dark matter, […]
