What if dark matter—the invisible force sculpting our universe—was once pure light? A bold new theory suggests that massless, high-energy particles in the early universe collided, cooled, and abruptly transformed into the heavy, slow particles we call dark matter. Not only does the model explain thi...

The Dark Energy Survey has discovered 17 dwarf galaxy candidates in the past six months, leaving scientists to believe that there could be many more galaxies hiding in our cosmic neighborhood. Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discover...

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. Despi...

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 my...

The IceCube Collaboration and DM-Ice have announced new observations on cosmic neutrinos and the nature of dark matter. Yale University physicists are part of two international research efforts at the South Pole — the IceCube Collaboration and DM-Ice — that have announced new observations on cosmic ...

The Dark Energy Spectroscopic Instrument has archived it second major milestone, approval of Critical Decision 2 (CD–2) authorizing the project’s scientific scope, schedule, and funding profile. DESI, the Dark Energy Spectroscopic Instrument, is an exceptional apparatus designed to improve our under...

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,...

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 str...

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 f...

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 Bl...

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...

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, gravitational waves from merging black holes, or cosmi...

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 do...

Researchers are using a large sample of galaxy cluster to investigate dark energy, showing that dark energy has not changed over billions of years. Astronomers have used data from NASA’s Chandra X-ray Observatory, ESA’s Planck, and a large list of optical telescopes to develop a powerful new method ...

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 alterna...

A new study details the results from the largest-ever, three-dimensional map of distant galaxies. The map is one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe. A team of hundreds of physicists and astronomers have announced result...

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 o...

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 aroun...

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 particl...

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 Chi...

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...

Researchers from Yale University are using a new detection device to search for dark matter in the form of axions, a theorized subatomic particle that may make up as much as 80% of the matter in the universe. Led by Yale physicist Steve Lamoreaux, a team of scientists announced the first results of ...

Using NASA’s Fermi Gamma-ray Space Telescope, a team of astronomers has discovered a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy. Gamma rays ar...

A team of astrophysicists has produced one of the highest-resolution maps of dark matter to date, offering a detailed case for the existence of cold dark matter. The dark matter map is derived from Hubble Space Telescope Frontier Fields data of a trio of galaxy clusters that act as cosmic magnifying...

A new set of observations of very young galaxies show that they are completely dominated by ‘normal’ matter, suggesting that dark matter plays a much smaller role in early star systems than in today’s galaxies. The new the findings by a team of researchers led by Reinhard Genzel of...

New research reveals that the outer parts of massive disc galaxies 10 billion years ago were rotating less quickly than the spiral galaxies, like the Milky Way, that we see today. New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion year...
