Clumps of dark matter might be shooting through the Milky Way’s stars.
Lone stars that roam through intergalactic space might one-day probe the nature of dark matter.
If proven right, this theory could be one of the most important developments in 21st-century physics.
And this could prove the perfect opportunity to identify the elusive form of matter.
In doing so, they’ve come up with evidence that might tell us what dark particles and forces might or might not lurk beyond the Standard Model.
Probably the most interesting you’re going to read today.
The findings might help piece together the evolution of the universe.
A new take on the whole ‘twinkle twinkle’ thing.
The elusive dark matter surprises us once again… this time by being absent.
It’s an exciting time to be a scientist.
We thought the Milky Way was special. Now, scientists have found a glitch elsewhere which challenges established physics.
This map shows how a dark matter bridge connects galaxies together.

The findings could reveal the location of the missing matter of our universe.
Invisible dark matter continues to elude scientists
The image above is a timeline with each frame showcasing a stage in our Universe’s evolution, from humble beginning to present date (left to right), as simulated by the Argonne National Laboratory. Called the Q Continuum simulation, this is the most complete cosmological simulation to date covering a volume of 1300 Mpc on a side (one Mpc = 3.08567758 × 1022 meters) where half a trillion particles evolved for a mass resolution of ~1.5×108 Msun.
Matter accounts for 31.7% of the mass-energy content of the universe, and 84.5% of the matter is dark matter. In other words, what we can measure today (ordinary matter) accounts for only a tiny fraction of the Universe’s mass-energy content. For years, scientists have been on the lookout for the elusive dark matter particles, as well as signs of dark energy. Efforts so far have been to no avail. Despite the setbacks, we know a thing for sure: dark matter exists. If it’s there, we’ll eventually find a way to detect it, but what if we’ve gone about this the wrong way? US physicists suggest a different approach: instead of looking for dark matter particles, we should be looking for evidence of their collision – dark radiation.
Astronomers have discovered a whopping 854 new ultra-dark galaxies which might have large quantities of the elusive dark matter, which makes out most of our universe.
This is the first map in a series of maps that will be stitched together to form a grand picture of how dark matter is distributed across the Universe. Dark matter is basically invisible, which is why it’s called dark in the first place, so scientists rely on indirect observations like the gravitational effects it poses to locate and map it. What we’re seeing now is only 3% of the area of sky that the Dark Energy Survey (DES) will document over its slated five-year-long mission.
At the core of a newly found dwarf galaxy, astronomers discovered a mysterious source of gamma rays that may signal the presence of the mysterious dark matter. If this is confirmed, then it would be the first time we see dark matter through anything else than its gravitational pull.
