The world's largest and most sensitive radio telescope is officially open for business according to Xinhua, China's official state-run media. The FAST Radio Telescope saw first light in 2016 but has been undergoing testing and commissioning since t

A new SARS-like virus has killed six people in China and infected nearly 300 others.

Snakes – the Chinese krait and the Chinese cobra – may be the original source of the newly discovered coronavirus that has triggered an outbreak of a deadly infectious respiratory illness in China this winter.

The Doomsday Clock has jumped closer to midnight than it's ever been in its 73-year history, indicating looming apocalyptic threats.

Scientists continue to push the boundaries of what cameras are capable of – like a newly developed phase-sensitive compressed ultrafast photography (pCUP) device, which is capable of snapping an impressive one trillion frames every second.

Betelgeuse keeps getting dimmer and everyone is wondering what exactly that means. The star will go supernova at the end of its life, but that's not projected to happen for tens of thousands of years or so. So what's causing the dimming?

SpaceX is poised to launch its first astronauts into space this spring: Bob Behnken and Doug Hurley.

There's a lot of stuff up there, whizzing around in low-Earth orbit. Given the thousands of old, defunct satellites that can no longer communicate with Earth, it's surprising how seldom they collide; but just such a collision might happen this week

How serious is the coronavirus outbreak? What are its symptoms and how contagious is it? Experts studying the new virus still have key questions to answer before they can assess its danger.

On Monday, researchers from Japan's Osaka University announced the successful completion of a first-of-its-kind heart transplant.

The UN health agency on Thursday declared an international emergency over the deadly novel coronavirus from China - a rarely used designation that could lead to improved international co-ordination in tackling the disease.

A couple of years ago, astronomers marvelled over the discovery of the hottest planet in the known Universe. And just when you thought KELT-9b couldn't get even more insane, it goes and outdoes itself.

Scientists have developed a new type of smart bandage that can signal the type of bacterial infection it's protecting, just like a traffic light, as well as release the right type of drugs on demand.

The US Food and Drug Administration approved a drug to treat life-threatening allergic reactions for the approximately 1 million children in the US with peanut allergies.

The new coronavirus spreading in China appears to be similar to SARS in two important ways: They share 80 percent of their genetic codes, and both originated in bats.

As beneficial as current solar panel technology has been in our quest to switch to renewable energy, such panels can't generate electricity at night. Now, new research suggests it could be possible to design panels that can operate around the clock

A team of researchers at the French National Institute of Health and Medical Research in Bordeaux have grown yarn from human skin cells that they call a "human textile" - and they say it could be used by surgeons to close wounds or assemble implant

In 2017, astronomers captured a mysterious signal from deep space. For mere milliseconds, it flared brightly in the radio spectrum and fell away, and that seemed to be that. But it wasn't.

Update: In a Twitter response to this article, SpaceX CEO Elon Musk says that the reality of things is unsurprisingly a bit more complex. As noted, the standards and requirements for aerospace hardware are much stricter than those needed for the water towers…

The epic collision between two neutron stars in 2017 really is the science gift that keeps on giving. As they merged, gravitational waves rippled out across the Universe; now reverberations from that event could confirm a decades-old hypothesis abo
