Scientists Discover Rare, Nearly Invisible Galaxy Dominated By Dark Matter
According to researchers, approximately 99 percent of this galaxy's total mass is dark matter.

Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core
Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matt...

James Webb Telescope Finds Galaxies Nearly as Old as the Early Universe
NASA’s James Webb Space Telescope has revealed early galaxies that appear almost as old as the universe itself. By analyzing 31 galaxies at high redshift, researchers estimated stellar ages of around 600 million years—close to the universe’s age at that epoch. One galaxy may even seem older than the universe, posing a potential challenge to t...

Study Reveals Rare Black Hole Blast Behind Powerful Neutrino That Hit Earth In 2023
Scientists believe that studying these explosions can help understand where such powerful neutrinos came from and can also provide new information in understanding the mystery of dark matter.

Dark Matter May Not Exist, Study Suggests Gravity Works Differently at Cosmic Scales
A new theoretical study suggests dark matter may not exist, proposing instead that gravity behaves differently across vast cosmic distances. By modifying how gravity weakens over scale, the research explains galaxy rotation and lensing effects without unseen particles, raising questions about long-standing cosmological models and inviting a fresh l...

Gravity May Behave Differently Across the Universe, Study Suggests
A new study suggests dark matter may not exist. Physicist Naman Kumar proposes gravity weakens differently across vast distances, following a 1/r rule. This modified gravity model reproduces galaxy rotation curves using only visible matter, challenging long-held assumptions about unseen mass in the universe, and reshaping theories of cosmic structu...

Impossible Neutrino Detected on Earth May Come From an Exploding Primordial Black Hole
A mysterious neutrino detected in 2023 may be debris from an exploding primordial black hole. Scientists say the ultra-energetic particle defies known cosmic sources and could represent Hawking radiation, offering rare insight into early-universe physics and the possible nature of dark matter while challenging theories of black holes and cosmology.

NASA's New High-Resolution Map Shows Dark Matter In "Stunning Detail"
The map provides insights into the universe's evolution, tracing dark matter's influence back to when galaxies were forming most actively.

James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

New Dark Matter Simulation Could Change How Galaxies Are Thought to Evolve
Scientists at the Perimeter Institute have developed a new simulation code, KISS-SIDM, to study self-interacting dark matter. The tool shows how rare dark matter interactions can heat and collapse galaxy halos, potentially explaining dense galactic cores and the early formation of supermassive black holes.
