Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent and role in shaping the universe.

New research reveals how quiet galactic engines can help shape entire galaxies.

Interstellar comets are the original cosmic explorers, and by studying their metallic whispers, we are learning the secrets of worlds we may never see directly.

Astronomers witnessed a star emitting as much energy in mere moments as our sun puts out in a few months. The dramatic observation gives a direct look into the brutal physics of these stellar events.

We need to talk about antimatter.

There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up.

For over two centuries, we have watched the red giant R Leonis dim and brighten with regularity, but this 'heartbeat' is beginning to speed up near the end of the star's life.

At first glance, it seems like our understanding of physics forbids free will.

Searches for dark matter particles have come up empty so far, driving theorists to get more creative with their ideas.

The axion could be a contender to explain the mystery of dark matter.

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Astronomers are just beginning to scratch the surface of the complex, and sometimes violent, relationships between planets and their parent stars.

While the existence of extra dimensions is a cool idea, it's currently not supported by any evidence

The astronomers estimate that this galaxy will deplete itself of gas in only a few hundred million years.

Regular stars collapse and die once they run out of fuel for their nuclear reactions, but the white dwarfs just sit there, hanging out, for eternity.

The weak nuclear force doesn't play by the normal rules — and, in fact, it breaks one of the biggest rules of all.

If you think you've met the wildest exoplanet yet, you haven't learned about TOI-4507 b. This strange world breaks almost every known rule for how planets should behave.

If the universe is expanding, then what is it expanding into, and what is it expanding from? Where's the edge of the universe, and where is its center?

We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these planets be called "rocky giants" instead.

As the name suggests, particle accelerators involve accelerating subatomic particles to incredibly high speeds and smashing them into tiny targets.

NASA plans to send the ISS into Earth's atmosphere in 2030, and it has no plans for a replacement — at least, not directly.

It will take the most sensitive instruments ever imagined to reveal ripples from the Big Bang, but they could change our understanding of the entire universe.

Astronomers just ruled out merging black holes as a possible solution to a giant discrepancy plaguing cosmology.

A galaxy in the early universe was rich with oxygen, astronomers have found. The discovery raises questions about how early life could have first appeared in the universe.
