Is it possible to build a Dyson sphere that isn't catastrophically unstable? New research says yes, but only in one type of star system.

The mysterious Antikythera Mechanism is 2,000 years old and has long puzzled scientists. New research into its triangle-shaped teeth may finally reveal its intended purpose.

Physicists are finalizing plans for MATHUSLA, a powerful new addition to CERN's Large Hadron Collider that will detect long-lived particles and potentially open the door to new physics.

If such worlds exist, they could be among the most common life-bearing planets in the galaxy.

Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' that reverse the growth of the cosmos, a new pre-print study hints.

The recent discovery of a stupendously powerful neutrino has left scientists scratching their heads. New research suggests it could be evidence that Stephen Hawking was right about the nature of black holes and the early universe.

The most powerful cosmic rays in the universe currently have no explanation. New research suggests that exotic, self-annihilating particles in our own galaxy may hold the answer.

Chinese scientists have announced details on the upcoming China Space Station Telescope (CSST), a cutting-edge observatory that will rival the JWST.

Let's explore the possibility of traveling to universes beyond our own — if they so exist, that is.

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought.

The cores of galaxies may not be made of what we thought, new research suggests — they could hold one giant, invisible star made of mysterious "fuzzy" matter.

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."
