If you believe popular science headlines, our cosmos could unravel at any instant. It's very unlikely, but the idea's core questions are still worth asking.

New data from the James Webb Space Telescope says that we'll need to rethink our model of the universe, and scientists are very excited.

A new paper making big waves says that the cosmos is 26.7 billion years old. The catch? It relies on phenomena we've never seen before.

Imagine stars millions of times larger than the Sun powered by black holes. It sounds too bizarre to be true, but scientists think they may be responsible for today's universe.

We're taught that our universe looks and works the same way in every direction. That may not be entirely true.

A new study sees evidence of more than a dozen galaxies that seem to lack dark matter and raises big questions about our ideas of galaxy formation.

Why do popular science news keep offering new theories about the basic shape of our universe every week?

We might know that dark matter is everywhere, but we know very little about it. So, what do we understand about this mysterious but critical component of the universe?

For the first time, an AI was trained how to simulate a universe 600 million light years across. Does how fast it was able to do it and how well it understood its task tell us something profound about the cosmos?

Galaxies seemingly lacking dark matter which threatened to rule out alternative ideas about what dark matter could be may actually be full of it, according to a second, in depth look.

Are two galaxies which seem to lack dark matter proof that dark matter must be a particle rather than a quirk of gravity at cosmic scales. Well, it's actually kind of complicated...

Theoretical physicists seem ready to move on from looking at dark matter as unknown particles we've yet to discover, and consider it a side-effect of gravity at cosmic scales.

If you imagine galaxies as tranquil clouds of gas and dust, lit up by billions of pinpoints of light, a 3D map of the Milky Way and the details behind it will show you otherwise.

It turns out that one of the oldest objects in the known universe is only a few thousand light years from Earth.

Astronomers discovered a large proto-supercluster that shows us just how quickly the universe we see today organized itself.
