Astronomers have been able to get their closest, most detailed look yet at the first stages of a dying star – a supernova known as SN 2018oh – using a combination of super-powerful telescopes out in space and based here on Earth.

There's mounting pressure on the world to grapple with its plastic addiction. Landfills and oceans alike are choking on waste plastic, which is made from crude oil and can take centuries to decompose.

A Falcon 9 rocket with a twice-flown first stage lifted off from California's Vandenberg Air Force Base today (Dec. 3), carrying 64 tiny satellites to orbit.

For the past two years, the OSIRIS-REx spacecraft has sailed across the solar system by the light of the stars. Like ancient mariners and the Apollo astronauts, it needed the constancy of the constellations to navigate the dark unknown.

There's no time to lose.

The world has not done enough to improve vaccination coverage, and now, measles is experiencing a resurgence in nearly every corner of the globe.

Last month, new research from Harvard and Yale led to a flurry of news claiming scientists were proposing to 'dim the Sun' in an "ingenious but as-yet-unproven way to tackle climate change".

A new video gives an amazing rocket's-eye view of a SpaceX booster's unsuccessful bid to return to terra firma today (Dec. 5).

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.
