A new optical instrument that can detect plant-based organisms from kilometres away due to the unique way living things reflect light could one day help in the search for life beyond this planet, new research suggests.

We humans like to put labels and boundaries on things. For example, the boundary between Earth's atmosphere and space is the Kármán line, the point at 100 kilometres (62 miles) altitude where aeronautics end, and astronautics take over.

Neutron stars are among the densest-known objects in the universe, withstanding pressures so great that one teaspoon of a star's material would equal about 15 times the weight of the moon. Yet as it turns ...

This footage is evolution in action, and it's absolutely breathtaking.

Diving to the bottom of the ocean is arguably harder than rocketing into space.

As far as environmental supervillains go, atmospheric carbon is the kingpin of crime. And just like in the comic books, every time we think we have a way to lock it up for good, it gets away from us.

Remember when the Solar System was simple? When you learned to say My Very Easy Method Just Sped Up Naming Planets? Astronomers just had to go mess it up, didn't they.

After years of delays, SpaceX and NASA are closing in on the first experimental launch of a commercial spaceship designed to fly astronauts into orbit.

In the dimly lit spaces of our Solar System beyond Neptune's orbit lies the Kuiper Belt. This a region between about 35 and 50 times further from the sun than the Earth, populated by icy bodies so sparsely distributed that they never had the chance

How many times have you thought about starting a company, taking a year out to write that novel or leaving a loveless relationship but ended up doing nothing about it? A fear of regret – which is a powerful driver of maintaining the status quo in

A new era in spaceflight.

Sixty-seven million light-years away, a galaxy is blowing enormous bubbles. We know what they are. Known as nuclear superbubbles, the structures are likely created by the supermassive black hole in the galaxy's centre. Now, thanks to new data, we k

In the history of the HIV pandemic, only one patient had ever successfully shown the most common strain of the virus, HIV–1, could be put into remission. Until now.
