Galaxies spin faster than they should. Space is spreading apart when it shouldn't. And it's all starting to feel like we're forever going to be in the dark when it comes to the big questions in physics.

Researchers have developed a test that could be used to diagnose all cancers. It is based on a unique DNA signature that appears to be common across cancer types.

In our never-ending quest to understand what happens to us after we die, humans have long seen the rare phenomenon of near-death experiences as providing some hints.

NASA's Mars InSight lander has captured three more incredible images of itself on the surface of the Red Planet.

When it comes to prodding the very boundaries of the Solar System we all reside in, astronomers have had a notoriously tricky time of figuring out where those edges truly lie.

It's time to say goodbye to one of the most storied explorers of our age: Voyager 2 has entered interstellar space.

NASA’s OSIRIS-REx mission arrived at Bennu on 3 December, and its first results show that the asteroid is chock-full of water and covered in huge boulders

The small object Ultima Thule swims amid a sea of distant stars in a new photo captured by NASA's approaching New Horizons around midnight EST (0500 GMT) on Dec. 1.

Without T-cells, the cells responsible for fighting off foreign cells, we humans are pretty vulnerable to disease. The T-cells themselves however rely on immune system sentinels, dendritic cells, to seek our and flag anything suspicious.

You probably don't stop to think about this often, but right after the birth of the Universe, matter was not in the form we recognise today.

NASA's InSight lander has taken its first selfie on Mars.

The OSIRIS-REx team has two major tasks to accomplish before the spacecraft slips into orbit around the asteroid Bennu on Dec. 31.

NASA's Parker Solar Probe, the first human-made object to fly into the Sun's corona, completed its first solar flyby on November 11, collecting a wealth of unprecedented data about the workings of our magnificent home star. And now, weeks later, th

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships.

The death of a binary star can be a spectacularly violent thing.

Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).

It's official: astronomers found a new dwarf planet in our Solar System - and it's the most distant object ever observed in our Solar System.

Nooooo.

Scientists have known for some time that Earth's atmosphere loses several hundred tons of oxygen each day. They understand how this oxygen loss happens on Earth's night side, but they're not sure how it happens on the day side.

While the presence of liquid water on Mars remains an ongoing topic of intense interest, we know that there is plenty of water ice adorning the Red Planet - and boy can it ever look amazing, as new images from the European Space Agency's Mars Expre
