The space telescope’s findings challenge the notion of a galaxy brimming with life.

But make sure you bring the fossegrim the proper offering—or else.

The Te’omim Cave in the Jerusalem Hills is filled with skulls and oil lamps — objects a new study says may have been used in dark rituals.

The big question isn’t whether the Universe is expanding at 67 or 73 km/s/Mpc. It’s why different methods yield such different answers.

Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?

The idea of black holes has been around for over 200 years. Today, we’re seeing them in previously unimaginable ways.

In all of human history, only 5 spacecraft have had the right trajectory to exit the Solar System. Will they ever catch Voyager 1?

In the night sky for March of 2022, only stars and the Moon, not planets, will greet you. The real show, however, arrives just before dawn.

The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.

Foster your own moments of mystery.

Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.

Great tidal ranges are relatively rare on a global scale — and can be very deadly to the unsuspecting foreshore walker.

In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.

Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.

Atomic nuclei form in minutes. Atoms form in hundreds of thousands of years. But the “dark ages” rule thereafter, until stars finally form.

Einstein’s theory of general relativity introduced the concept of space having a shape. So, what is the shape of space?

A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.

Acting “little and often” has huge consequences and they’re not always good — but awareness yields solutions.

Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Recreating them in the lab is not easy.

Is mathematics woven into the very fabric of reality? Or is it merely a product of the human mind?

It is generally ineffective, occasionally poisonous, and driving numerous species to the brink of extinction.

Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.

In the infant Universe, particle physics reigned supreme.

Our Sun will continue to grow, becoming a red giant and then a planetary nebula. Here’s how large it will get.

The most celebrated genius in human history didn’t just revolutionize physics, but taught many valuable lessons about living a better life.

2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.
