It's Official: Vera Rubin Observatory Named to Honor Dark Matter Scientist

HONOLULU — A U.S. facility designed in part to solve the mysteries of dark matter now officially carries the name of Vera Rubin, the scientist who concluded that the elusive substance must exist. That announcement came Monday (Jan. 6) here, at the 235th meeting of the American Astronomical Society, during...

Self-destructing dark matter may be flooding the sky with gamma-rays, study suggests

Gamma-rays — the brightest, most powerful light in the universe — sail across the sky invisible to human eyes. These exceptionally energetic bursts of radiation flash out of supernova explosions, spark off of colliding neutron stars, and spew forth from the hungriest black holes. When astronomers can catch them with...

Did German physicists accidentally discover dark matter in 2014?

Could we have already discovered dark matter? That's the question put forth in a new paper published Feb.12 in the Journal of Physics G. The authors outlined how dark matter might be made of a particle known as the d*(2380) hexaquark, which was likely detected in 2014. Dark matter, which...

Hunting for dark matter — inside the Earth

Dark matter is a hypothetical component to our universe, used to explain many strange behaviors of stars and galaxies. Despite the almost overwhelming evidence that dark matter does indeed exist, we still don't know what it's made of. Detectors scattered around the world have been operating for decades, trying to...

Scientists use the Milky Way to hunt for dark matter

Scientists studying a mysterious signal from far-off galaxies didn't find dark matter as they'd hoped. But the inventive new technique they used to detect this strange signal, which uses our own galaxy to hunt for dark matter, could elevate the hunt for the elusive material. For decades, scientists have been...

A long-lost type of dark matter may resolve the biggest disagreement in physics

One of the deepest mysteries in physics, known as the Hubble tension, could be explained by a long-since vanished form of dark matter. The Hubble tension, as Live Science has previously reported, refers to a growing contradiction in physics: The universe is expanding, but different measurements produce different results for...

Dark matter hunter who found unexpected, giant 'Fermi bubbles' wins $100,000 physics prize

Editor's Note: This story was corrected at 12:30 p.m. E.D.T. to note that Slatyer received $100,000, not $50,000, for her work. Tracy Slatyer, known for hunting dark matter in our galaxy and discovering evidence of an ancient Milky Way explosion, has won a $100,000 New Horizons Prize in Physics. Slatyer,...

What is dark matter?

Dark matter is a mysterious non-luminous substance making up the vast majority of matter in the universe. Though experts have observed the gravitational effects of dark matter for decades, scientists remain baffled as to its true nature. Who discovered dark matter?In the late 19th century, astronomers began speculating about unseen...

Astronomers claimed galaxy was 98% dark matter. They were wrong.

Back in 2016, researchers claimed to have found a galaxy made almost completely of dark matter and almost no stars. Now, on closer examination, that claim has fallen apart. The galaxy, Dragonfly 44 (DF44), belongs to a class of mysterious objects known as ultra-diffuse galaxies or UDGs. Researchers have debated...

Physicists search for imprints left by dark matter haloes as they swoosh through galactic gas

The search for dark matter – an unknown and invisible substance thought to make up the vast majority of matter in the universe – is at a crossroads. Although it was proposed nearly 70 years ago and has been searched for intensely - with large particle colliders, detectors deep underground...

Distant alien planets could be turned into dark matter detectors

Dark matter could be detected on alien worlds orbiting distant suns, a new study suggests. This elusive form of matter is one of the most frustrating and mysterious aspects of modern astronomy. Thought to account for 80% of all matter in the universe, it is completely invisible, detectable only through...

Cosmic bubbles may have forged dark matter, new theory suggests

Ballooning cosmic bubbles in our early universe may have led to the current abundance of dark matter, the elusive substance that tugs on the stars, yet emits no light, a new study suggests. The theory, described Oct. 9 in the journal The Physical Review Letters, may explain exactly how dark...

Mystery of galaxy's missing dark matter solved. (And it involves a thief.)

A small, mysterious galaxy 44 million light-years away is finally yielding up its secrets. Revealed last year to have a shockingly low amount of dark matter, the galaxy NGC 1052-DF4 posed a significant challenge to our models of galaxy formation. Those models yet live another day. According to new research,...

6 ways the hunt for dark matter changed in 2020

Perhaps the most confounding problem in astrophysics is dark matter. Vera Rubin discovered it in the 1970s, showing that galaxies spin much faster than the visible matter in them can explain. Now researchers believe dark matter makes up 85% of the mass of the universe, and is largely responsible for...

Mysterious 'kick' just after the Big Bang may have created dark matter

One of the lingering mysteries of the universe is why anything exists at all. That's because, in the universe today, matter and its antimatter counterpart should form in equal amounts, and then these two oppositely charged types of matter would annihilate each other on contact. So all the matter in...
