In 1996, over 20 years ago, then US President Bill Clinton made a short speech on what was, at the time, a monumental discovery: one that would someday launch a whole new field of science, called astrobiology.

Ice is a complex beast. While you and I only ever come into contact with one kind of it, scientists actually know of around 20 different molecular varieties – some so esoteric and rare, they may only exist inside computer simulations, or buried w

Over the years, researchers have learned a lot about dinosaur anatomy, but there's one feature that keeps eluding us. 

When there’s a meteor shower on the moon, the impacts cause puffs of water, which means that it’ll be simple for us to get that water to use for exploration

The immune system does essential work in keeping us alive and healthy, but when it malfunctions it can cause problems – and there's new evidence that one of those problems could be dental cavities.

For the first time, scientists have managed to bring a flutter of life back into dead brains. With a new system, neuroscientists have restored some cellular and molecular function to the brains of pigs that had been dead for four hours.

In 1869, a Siberian called Dmitri Mendeleev presented a brand new version of the periodic table of elements to his peers at the Russian Chemical Society.

It's the big mystery: Intelligent life should be out there in the Universe, so why haven't we found any evidence for it? This question is called the Fermi paradox, and there are a few potential answers.

There's a trick to night-time photography: longer exposures. They soak up more light, making everything pop brilliantly in your shot, provided your camera stays really, really still.

In the Hollywood blockbuster The Core, the planet's core suddenly stops rotating, causing Earth's magnetic field to collapse. Then bursts of deadly microwaves cook the Colosseum and melt the Golden Gate Bridge.

Not everybody hears the same. Numerous studies have shown people who become blind early in life can experience enhanced auditory powers compared to sighted people, but a new experiment appears to have revealed the neural basis of this phenomenon fo

NASA's InSight Mars lander may have recorded its first 'Marsquake' - seismic tremors, faint but unmistakable deep in the belly of the red beast.

Since it was first launched on 24 April 1990, NASA's Hubble Space Telescope has made more than 1.4 million observations of nearly 45,000 celestial objects. For its 29th birthday, NASA has singled out just one.

The mysterious purple skyglow named STEVE was unmasked last year. Physicists proved that STEVE was not a new kind of aurora - in fact, it's not any kind of aurora at all. But that still left one big, gaping question: What exactly is it?

Special Relativity. It's been the bane of space explorers, futurists and science fiction authors since Albert Einstein first proposed it in 1905. For those of us who dream of humans one-day becoming an interstellar species, this scientific fact is

It came out of nowhere. Just a few short weeks ago – in an alternate reality otherwise identical to our own – it popped up on our screens: a giant asteroid hurtling through space, and headed straight for us.
