There's a significant imbalance between matter and antimatter in our universe, but a strange particle called "the Majoron" could finally explain it, an audacious new study suggests.

As black holes slowly vanish through Hawking radiation, their information may be preserved in subtle space-time ripples, a new theory suggests.

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".

When stars explode as supernovas, they can cause serious cosmic carnage. Is Earth in any danger from any nearby stars?

To explore the galaxy and hunt for resources, intelligent aliens might need to turn their home stars into natural spaceships, a new paper suggests. A few known star systems might fit the bill.

While such organisms may or may not exist in the universe, the research has important implications for future human endeavors in space.

New theoretical research suggests primordial black holes could one day help researchers locate invisible dark matter.

New research suggests holographic dark energy could stop the universe's expansion.

Strange, ultraheavy stars that are rich in barium grow massive by cannibalizing their companions, scientists discover after finally catching these stellar leeches in the act.

Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space.

Unlike the other planets in the solar system, Mars is distinctly triaxial, meaning it is an ellipsoid with different sizes along all three axes.

A flowery passage in a 6,000-year-old Hindu text may be the earliest known reference to a solar eclipse, describing the sun as being "pierced" with darkness and gloom and proposing that evil beings had caused the sun's "magic arts to vanish."

Every so often, astronomers detect a supernova explosion that's 100 times brighter than it should be. A new paper may reveal the strange source of these "superluminous" supernovas.

A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon.

While headlines around the world claimed that ancient galaxies discovered by the James Webb Space Telescope were "breaking" our understanding of the Big Bang, the truth is much more nuanced — and much more interesting.

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

A strange class of space rock known as a "dark comet" has qualities of both asteroids and comets — and the hard-to-spot objects may pose a larger threat to Earth than we thought, according to new research.

Scientists recently identified seven stars in the Milky Way that could potentially be gigantic alien structures called Dyson spheres. New research proposes an alternative explanation: Those are just cosmic "hot DOGs" in disguise.

Mysterious dark matter could slosh over our planet like a wave. If it does, it may produce telltale radio waves in Earth's atmosphere, new theoretical research suggests.

New research shows how disruptions to binary star systems could be the key to detecting space's most confounding substance — dark matter.

When there are multiple supernovas in the same galaxy, they can leave enormous voids that tamper with the balance between dark matter and regular matter. Over time, this can throw entire galaxies into chaos.

The moon controls the tides, impacts marine ecosystems, and subtly influences time on Earth. So what would happen if the moon suddenly disappeared?

A fringe theory called "panspermia" suggests that lifeforms can spread to new planets by hitching rides on meteors. New research lays out a roadmap for finding where these hypothetical, planet-hopping aliens may reside.
