You might not think about it much, but water is super weird. It doesn't behave like any other liquid.

Japan's space agency said it successfully dropped a small bomb on an asteroid on Friday as part of its mission to better understand the history of the Solar System.

It's one of the most enduring mysteries of the Sun: why the superheated surface of this great ball of glowing plasma is actually cooler than its outer atmosphere, called the corona.

Matter takes many shapes, but most of us are familiar with the basic three states - solid, liquid, and gas. Now, for the first time, scientists have discovered that it's possible for matter to exist in two of these states at once.

No. Stop. Scroll back up. Look at that picture. Stop scrolling down and look again. What you're looking at is history. That is the very first direct image, ever, of the event horizon of a black hole.

By now, we've all seen the history-making snapshot of the supermassive black hole at the centre of galaxy M87 staring back at us like the flaming eye of a vengeful god.

A new type of air filter has the potential to work faster, cheaper and better than any other, killing virtually all airborne bacteria and viruses in a fraction of a second.

A dwarf planet known only as 2007 OR10 is about to get a proper name after more than a decade - and the public can help decide what we call it

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.
