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.

Physicists have measured no changes in time or space for any of the fundamental constants of nature.

We don't really know how the universe was created, though most astrophysicists believe it started with the Big Bang.

There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.

Astronomers have found a way to catch planet-murdering stars red-handed and figured out how long we have until the case grows cold.

New research suggests that a wandering companion may have played a role in Betelgeuse's antics of late 2019.

Researchers have proposed what's perhaps the most exotic explanation to date for the source of the universe's seed magnetic field: cosmic strings.

A model of exotic dark matter suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic, pancake-like sheets.

The top quark is about 100 trillion times heavier than the up quark. But why?

A team of physicists has found that the remnant of a neutron star merger observed in 2019 has just the right mass to be a strange hypothetical quark star.

Electrons were once thought to orbit a nucleus much as planets orbit the sun. That picture has since been obliterated by modern quantum mechanics.

The concept of atoms had been floating around off and on for a few millennia, but it took some clever experimentation to pinpoint their existence.
