Dark matter, the invisible material that makes up the vast majority of the universe's mass, may collect itself to form atoms, a new simulation shows.

Astronomers have used the youngest objects in the Milky Way to build a new map of the galaxy's spiral arms, and the results are far messier than expected.

In a distant star system, a sunlike star orbits an invisible object that may be the first example of a 'boson star' made of dark matter, new research suggests.

A new paper discusses how light interacts with theoretical objects called "topological solitons" — kinks in the fabric of space-time that look just like black holes.

New research suggests that Hycean exoplanets would suffer from a catastrophic runaway greenhouse effect, causing their oceans to boil away.

A large population of small black holes could have flooded the young cosmos with particles and radiation, creating their own black hole-powered Big Bang, physicists propose in a new paper.

These cosmic rays typically come from the extremely distant universe, from ultrapowerful events such as supernovas and quasars.

A massive, cold clump of material in the heart of the "Dragon cloud" is ready to form a single giant star, and astronomers got a rare glimpse of the event.

Astronomers have identified a new kind of pulsar that consumes an orbiting companion, filling in a missing link about how some of the strangest systems in the universe evolve.

Observations by NASA's DART spacecraft suggest that the asteroid Dimorphos formed from material flung into space by its spinning asteroid partner, Didymos.

Mercury is so strange that astronomers have not been able to explain its properties with simulations of the solar system's formation. But now, researchers have found an important clue.

The universe may be flat, but could still be shaped like a doughnut, weird patterns in leftover light from the Big Bang suggest.

When the universe's first stars emerged from the cosmic dark ages, they ballooned to 10,000 times the mass of Earth's sun, new research suggests.

The early universe may have been such a violent place that space-time itself fractured like a pane of glass, releasing gravitational waves that astronomers say we may have already detected.

Scientists have proposed a way that the universe could stop expanding, ending in a 'Big Crunch' that resets space and time as we know it.

Finding and studying these strange stars helps us understand the complicated life cycles of normal, more well-behaved stars.

A rotating universe would be capable of rotating your future into your own past, allowing you to travel back in time.

Intergalactic gas clouds are slightly hotter than they should be, new research claims, and theoretical particles called 'dark photons' could explain it.

Researchers confirmed that the distant galaxies discovered by the James Webb Space Telescope are, indeed, perfectly compatible with our modern understanding of cosmology.

Want to become a published astronomer? All it takes is a spare telescope, or at least a decent internet connection, and plenty of patience.

A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome.

What lurks at the center of a black hole? Studying the space-time ripples from black hole collisions could reveal an answer.

Einstein toyed with the idea of faster-than-light-particles but found that such particles violated a central rule of the universe: causality.

A special type of supernova might be able to destroy a planet's ozone layer years after the initial explosion.
