The invisible substance called dark matter remains one of the biggest mysteries in cosmology. Perhaps, a new study suggests, this strange substance arises from a 'dark mirror universe' that's been linked to ours since the dawn of time.

A new study combining two of Albert Einstein's famous predictions suggests that ripples in space-time can combine into 'gravitational lasers', firing out of black holes in random directions across the cosmos.

The presence of supermassive black holes in the earliest epochs of the universe has scientists stumped — but repeated explosions from tiny black holes may offer an explanation.

Many models of the universe predict the existence of countless invisible strings stretching across space. New research finds a way these strings might snap — and how we could feel the fallout.

Scientists modeled how black holes and neutron stars form after dying stars collapse, and explained why some get a hard 'kick' into interstellar space.

An entire universe made of 'dark' particles could exist within our own, and astronomers may know the first place to look: In the mysterious hearts of supposed 'mirror stars'.

The first life-forms capable of evolution could have appeared just moments after the Big Bang, a physicist explains.

Far from any galaxy, icy grains of dust in deep space may be able to form organic molecules, a new preprint study finds.

Dark matter may come in multiple particles and weights, similar to the ordinary elements on the periodic table, a new theory suggests.

The hellish super-Earth '55 Cancri e' may be constantly losing and re-growing its atmosphere, a new study of the planet's strange transit signals suggests.

Stars could be sliced in half by "relativistic blades," or ultra-powerful outflows of plasma shaped by extremely strong magnetic fields, an unpublished paper claims.

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.
