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.

New research suggests that the sun may hold dark matter in its fiery heart, and ghostly particles called neutrinos could lead us to it.

Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'

Invisible dark matter may be gathering in the ultra-dense innards of neutron stars, potentially causing them to detonate in massive explosions.

Meet the 'bubbletrons' — theoretical particle accelerators that may have helped build the universe as we know it.

What happens when an invisible star dies? It erupts in an invisible explosion, of course. New research describes how these unseen 'bosenovas' may behave.

Astronomers proposed a new mechanism behind mysterious fast radio bursts (FRBs), and it involves unlucky asteroids crashing into neutron stars.

From the Catholic priest who pioneered it, to how we can (almost) see it, here are 5 fascinating facts about the Big Bang.

Researchers have discovered a new 14-sided shape called the Spectre that can be used to tile a surface without ever creating a repeating pattern, ending a decades' long mathematical hunt.

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.

In the early universe, gravity may have been capable of creating light, a new theoretical paper finds.

Astronomers have a plan for using ripples in space-time to hunt for elusive intermediate-mass black holes around the Milky Way's center.

A new 13-sided shape is the first example of an elusive "einstein" — a single shape that can be tiled infinitely without repeating a pattern.

What's the biggest black hole in the universe, and is there a limit to how big black holes can get?

Within a month of the Big Bang, a second cosmic explosion may have given the universe its invisible dark matter, new research suggests.

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

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.

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.

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

Early life made an inhospitable Earth more habitable, and aliens could be doing the same thing on their worlds, new research proposes.

These hypothetical stars are the densest objects in the universe that can exist without becoming full-fledged black holes.

In quantum physics, particles exist in many states at once until you measure them. Can reality really work that way?

In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.
