Devices buried deep within the south pole detected highly elusive tau neutrinos blasted toward Earth by powerful astrophysical events.

Astronomers have detected high-energy neutrinos coming from within our Milky Way galaxy, potentially opening up an exciting new window of research.

"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored."

New research shows gamma-ray blasting blazars could also be belting Earth with "ghost particles," or neutrinos.

China's forthcoming Tropical Deep-sea Neutrino Telescope (TRIDENT) will search for the origins of cosmic rays in momentary flashes of light beneath the ocean's surface.

One astronomer proposes that, instead of building gigantic, expensive experiments on Earth, we should try another method of searching for dark matter: Looking to the stars.

Neutron stars smashing together may create and trap ghost particles called neutrinos, and this discovery could help us better understand how elements like gold are forged.

Neutron stars with surface temperatures millions of degrees cooler than expected rule out a swathe of possible models to describe the physics of such objects.

Neutron stars are the universe's most extreme stars, composed of matter so dense a teaspoon of it would weigh as much as Mt. Everest. So, when they collide, it's quite the event.

Neutron stars could act as gravitational traps for dark matter, forcing these mysterious particles to collide, annihilate and warm up otherwise cold dead stars.

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.

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.

NASA's Fermi Space Telescope has failed to see gamma rays from a nearby supernova that should be created when it generates the high-energy cosmic rays that bombard Earth in their trillions.

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.

Extreme collisions between neutron stars could create exotic particles beyond the standard model, including axions, the hypothetical particle that comprises dark matter.

Neutron stars are some of the weirdest cosmic objects, and the greatest mysteries lie deep in their hearts.

A puzzling discrepancy in measurements of the mass of the W+ and W– bosons, which are fundamental particles that carry the weak force, has been resolved by the Large Hadron Collider.

The mystery of what dwells within dead stars could be solved at last, thanks to supercomputer simulations that show neutron stars are comprised of "cold quark matter."

In the extreme hearts of neutron stars, fundamental particles are twisted into strange 'pasta' shapes that could reveal untold secrets about how dead stars evolve.

Astronomers have detected 21 rare systems with widely separated neutron stars and sun-like stars. These binaries are "one in a million" and challenge dead star binary formation models.

The neutron star stayed hidden for 37 years while lurking in the wreckage of a stellar explosion, Supernova 1987A.

The MeerKat Radio Telescope discovered an unknown object in the Milky Way heavier than the largest neutron star but lighter than the smallest black holes.

A unified approach of quantum physics and astrophysics may have brought scientists closer to understanding the "glitches" experienced by ultradense dead stars called neutron stars.

Astronomers are investigating a cosmic crime scene to determine why the death of a massive star left behind a highly magnetic "corpse."

A distant star has a dead star companion lurking in its vicinity that could be a monster-massive white dwarf, raising the question: how has it avoided being devoured by this cosmic zombie?

Using the Hubble and Gaia space telescopes, astronomers have discovered that a powerfully magnetic neutron star in the Milky Way wasn't born in a supernova.

New research indicates that matter ejected during the supernova death of a star can fall back to neutrons stars, giving rise to mysterious "low-field magnetars."

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests.

The skies may be full of invisible "boson stars" that could have a connection to dark matter.
