Dark matter, the elusive search: Latest discoveries and news
Roughly 80 percent of the mass of the universe appears to be dark matter: an invisible material that seems to interact with ordinary matter only through gravity, without emitting light or energy. Scientists cannot detect dark matter directly and don't yet know what it's made of, but they track its influence based on the motions of stars and galaxies. The presence of dark matter is necessary to explain the universe's current structure.

Latest about dark matter
Dead stars within supernova explosions could solve the dark matter mystery in 10 seconds
By Robert Lea published
If astronomers could catch bursts of gamma rays from supernova explosions that create neutron stars near the Milky Way, the mystery of dark matter could be wrapped up in 10 seconds.
5 galaxies in perfect alignment challenge our best model of the universe
By Sharmila Kuthunur published
Astronomers have discovered a group of dwarf galaxies with distinct features that challenge predictions made by the prevailing cold dark matter (CDM) model.
Somewhere in the multiverse, dark energy is helping stars and life form
By Keith Cooper published
The strength of dark energy in our universe is not optimized for forming stars, which means other universes might have a greater likelihood of producing life.
'Superhighways' connecting the cosmic web could unlock secrets about dark matter
By Paul Sutter published
Giant filaments crisscross the universe, connecting galaxy clusters like superhighways between cities. But due to their complex shapes, they are stubbornly difficult to measure.
Dark matter might make space-time ring like a bell around black holes — and we might be able to 'hear' it
By Paul Sutter published
To explain why dark matter particles haven't come up in any direct detection experiments, physicists have wondered if it may be a kind of particle known as an axion.
James Webb Space Telescope finds galaxies pointing toward a dark matter alternative
By Sharmila Kuthunur published
A new study suggests galaxies in the early universe appear much larger and brighter than expected, precisely as predicted by modified Newtonian dynamics, or MOND.
Dark matter might live in a dense haze around stellar corpses
By Robert Lea published
The extreme qualities of neutron stars could mean these dead stellar remnants gather dense clouds of hypothetical particles called "axions" around them, potentially shedding light on dark matter.
Massive, bustling Perseus galaxy cluster dazzles in new telescope image
By Keith Cooper published
Deep in the heart of the massive Perseus cluster, giant galaxies stir, stars are torn from their homes and hot gas radiates at more than 1 million degrees Celsius.
Euclid 'dark universe' telescope reveals 1st breathtaking images from massive 'cosmic atlas' map
By Robert Lea published
The "first page" of an incredible cosmic atlas being built by the Euclid Space Telescope has been released. The millions of stars and galaxies represent just 1% of the 3D map the mission will create.
Cosmic rays have surprising amounts of antimatter. Is dark matter responsible?
By Robert Lea published
There's too much antimatter in cosmic rays, showers of charged particles that pelt Earth. Could this be explained by annihilating dark matter? If so, does it point to the existence of WIMPs?
