Scientists thought the case of the cosmic rays' source was closed, but new evidence cracks it wide open again.

MIT: Dark matter at our galaxy's core may be blasting gamma rays

Ongoing Debate

Scientists thought they ruled out dark matter as the source of bizarre cosmic gamma rays coming from the core of the Milky Way. New evidence disagrees.

MIT: Dark Matter At Our Galaxy’s Core May Be Blasting Gamma Rays

New evidence resuscitated a theory thought to be debunked.

The tiny black holes keep growing until they collapse on themselves and cause a big kaboom.

New theory: Dark matter black holes are detonating stars

Extremely Metal

Scientists have a new guess for what triggers white dwarf stars to blow up in supernovae: tiny black holes made of dark matter growing in their cores.

New Theory: Dark Matter Black Holes Are Detonating Stars

The triggers build up at the star's core before exploding.

It really throws a wrench in astronomers' understanding of the universe.

19 newly discovered galaxies appear to be missing dark matter

Cosmic Mystery

Astronomers discovered 19 new galaxies that appear to be missing their dark matter. The discovery challenges our models of how galaxies form.

"This discovery of a possible fifth force [of nature] would completely change our understanding of the universe."

Physicists discover evidence of a new force of nature

Force Finding

Researchers have discovered new evidence of a fifth force of nature, and if confirmed, the work could help us understand dark matter.

Physicists Discover Evidence of a New Force of Nature

This could be the key to understanding dark matter.

Scientists are challenging long-held assumptions about the universe to hunt down dark matter.

New research: antimatter could be portal to "dark universe"

Exhausting Options

A team of physicists attempted a bizarre new way to spot dark matter: using antimatter probes. It hasn't worked yet, but the scientists have some ideas.

New Research: Antimatter Could Be Portal to “Dark Universe”

Scientists have a new plan to spot dark matter.

"Any indication that [dark energy] is not a constant would be revolutionary and spark intense theoretical work."

Scientists boot up new device to map the universe's dark energy

Dark Energy Conundrum

Last week, scientists achieved "first light" with the Mayall Telescope's Dark Energy Spectroscopic Instrument. It could teach us about dark energy.

Scientists Boot Up New Device to Map the Universe’s Dark Energy

The instrument has the potential to "spark a revolution in theoretical physics."

One image shows our neighboring galaxy, the Large Magellanic Cloud, in all its glory. Another shows two galaxy clusters interacting with each other.

Here are the first-ever images from the dark matter telescope

Galaxy Snapshot

Scientists just publicly presented the first ever images of the German space agency's (DLR) X-ray telescope eROSITA. And they're magnificent.

Here Are The First-Ever Images From the Dark Matter Telescope

The new telescope, according to one scientist, is "tracing out the dark matter structure of the Universe."

"Capture of a freefloating planet is a leading explanation for the origin of Planet 9 and we show that the probability of capturing a [primordial black hole] instead is comparable."

Astrophysicists: There may be black holes orbiting our Sun

Sky Dance

Researchers are suggesting that in the orbit of the Milky Way's sun may be a free-floating "primordial black hole" — or even more than one.

Astrophysicists: There May Be Black Holes Orbiting Our Sun

In a mind-bending new paper, researchers suggest that there could be black holes orbiting the Sun, out past Pluto.

"...this work can enable a large number of science projects throughout the research community."

Scientists will use a supercomputer to simulate the universe

Cosmological Cheat Sheet

Physicists at the Argonne National Lab are about to use the Mira supercomputer to simulate the universe, perhaps helping them find dark energy and matter.

Scientists Will Use a Supercomputer to Simulate the Universe

The simulation will be the basis for countless future studies.

"If dark matter were truly a remnant of the Big Bang, then in many cases researchers should have seen a direct signal of dark matter in different particle physics experiments already."

Dark matter may have preceded the Big Bang

Big Bang Theory

New research suggests that dark matter was already there before the Big Bang occurred, altering our understanding of the history of the universe.
