US EditionScientists May Have Found Dark Matter After 100 Years of Searching
Analysis reveals a gamma-ray excess at the Milky Way's center consistent with annihilation of weakly interacting massive particles, potentially the first direct dark matter evidence.
- Professor Tomonori Totani's analysis of NASA's Fermi Gamma-ray Space Telescope data identified a halo-shaped gamma-ray glow near the Milky Way's center, the paper said in the November 26, 2025, Journal of Cosmology and Astroparticle Physics.
- WIMP theory predicts weakly interacting massive particles annihilate in the Milky Way's galactic center, motivating focused searches given its dark-matter density.
- Measured energies include 20 billion electronvolt photons, with Totani's analysis indicating particles roughly 500 times the mass of a proton, consistent with WIMP annihilation and Fermi data.
- If confirmed, the result would be the first direct detection of dark matter and point toward physics beyond the Standard Model, marking a major development in astronomy and physics research community.
- Scientists urge caution and demand further analysis by independent research groups and searches in dwarf galaxies as the global scientific community seeks to rule out alternative explanations.

Scientists may have found dark matter after 100 years of searching
Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing new data from NASA’s Fermi Gamma-ray Space Telescope has detected a halo of high-energy gamma rays that closely matches what theories predict should be released when dark matter particles collide and annihilate. The energy levels, intensity pattern…
Scientists Claim to Detect Dark Matter for the First Time Ever
A team of astronomers say they may have detected dark matter, the invisible substance thought to make up over 85 percent of all matter in the universe, for the first time in history. The claim is controversial, and the findings, published in a new study in the Journal of Cosmology and Astroparticle Physics, will need to be borne out by further observations. But at least until it gets picked apart by other physicists, it’s one of the most exciti…
Did a NASA telescope really 'see' dark matter? Strange emissions spark bold claims, but scientists urge caution
A new study says observations from the NASA Fermi space telescope suggest a halo of dark matter around the center of our galaxy, but more information is needed to confirm the result.
After a Century of Searching, We May Have Finally Seen Dark Matter
Ninety five years after Swiss astronomer Fritz Zwicky inferred its existence from galaxies moving impossibly fast, researchers may have detected the first direct evidence of dark matter, the invisible scaffolding that holds the universe together. Using gamma ray data from NASA's Fermi Space Telescope, a Japanese physicist has identified a halo of extremely energetic photons around the Milky Way's center that matches predictions for annihilating …
The physicist Tomonori Totani from the University of Tokyo wants to have found an indication of dark matter in gamma radiation from space.
A new study claims to have found the strongest evidence yet for dark matter annihilation
In a recently published study, Tomonori Totani of the University of Tokyo's astronomy department claims to have observed evidence of dark matter annihilation. If the findings survive scrutiny, they could provide the strongest evidence yet not only of the existence of dark matter, but also of the theory that it...Read Entire Article
