Astronomers using with the Australian National University 1.3-m SkyMapper telescope have detected an extended dark matter halo around Tucana II, an ultrafaint...
In a paper to be published in the journal Physics Letters B, a duo of theoretical physicists from the University of Sussex shows that quantum gravity leads...
If ‘stupendously large’ black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful...
First theorized in the 1970s, axions are hypothetical particles that were proposed to preserve a time-reversal symmetry of the nuclear force. These particles...
In a new paper in the journal Physical Review Letters, an international team of theoretical physicists described a scenario for the formation of primordial...
Dark matter proponents theorize that most of the known Universe is actually made of material that doesn’t interact with light, making it invisible and...
Using the polarization data from ESA’s Planck satellite, a mission that have studied the Cosmic Microwave Background (CMB), the oldest light in the Universe,...
Astronomers using the NASA/ESA Hubble Space Telescope have detected tidal tails in NGC 1052-DF4, a dark-matter-deficient galaxy some 65 million light-years...
In a paper published this month in the journal Physical Review Letters, an international team of physicists described a new mechanism of dark matter production.

Using the MUSE and FORS2 instruments on ESO’s Very Large Telescope (VLT), astronomers have spotted a group of six galaxies around SDSS J1030+0524, a...
Using data on a sample of 756 galaxy clusters identified in the Sloan Digital Sky Survey (SDSS), a team of astrophysicists from the United States and Egypt...
Astronomers using the NASA/ESA Hubble Space Telescope have captured a striking new photo of an unusual spiral galaxy called NGC 5585.
This Hubble image...
The large mass of a galaxy cluster deflects light from background objects, a phenomenon known as gravitational lensing. The large-scale gravitational lens...
The so-called self-interacting dark matter theory helps explain why NGC 1052-DF2 and NGC 1052-DF4, a pair of ultra-diffuse galaxies located approximately...
In a new study, an international team of astronomers led by ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) combined data...
Astrophysicists using NASA’s Chandra X-ray Observatory have looked for signs of an as-yet undetected particle predicted by string theory, a set of models...
Physarum polycephalum, a single-cell organism known as slime mold, builds complex web-like filamentary networks in search of food, always finding near-optimal...
Dark matter is the mysterious substance that makes up roughly a quarter of the Universe. There is strong indirect evidence for its existence from measurements...
