Alexander Gerst, a German astronaut orbiting Earth from 250 miles (402 kilometres) up, has a warning for humans on the planet below him.

Matter ejected from a spinning disc of doom surrounding a black hole a mere 15,000 light years away has produced some of the most energetic rays of light ever witnessed from an object of its kind.

If the world is going to avoid catastrophic climate change, we need to stop consuming fossil fuels and start getting power from renewable energy sources – including geothermal energy, biofuels, hydropower, solar farms, and wind – as soon as pos

The Kepler mission is coming to an end.

A comparison of surveys taken of the sky years apart has revealed an empty space where a star 280 million light years away once sat.

Six years after Voyager 1 officially left the Solar System, it looks like its companion probe, Voyager 2, is getting close to the interstellar boundary as well.

NUST MISIS has developed strengthening modifiers for 3D printing products made of aluminum composites for the aerospace industry.

Hidden below the waves off the east coast of Australia, scientists have discovered a 'lost world' of epic volcanic peaks buried under the Tasman Sea, never before seen with human eyes.

When you think of vast organisms, it's hard not to think of giants like blue whales and redwood trees. But back in the 1980s, it was a single mushroom that broke records and forced a rethink on what it means to be an individual organism.

Booster rockets carrying a Soyuz spacecraft with a Russian and a US astronaut on board headed for the International Space Station failed mid-air on Thursday, forcing the crew to make an emergency landing.

By deleting key sequences of DNA in embryonic stem cells harvested from female mice, Chinese researchers successfully kicked off a new generation of the tiny mammals without the need for males to fertilise any eggs.

Of all the prehistoric creatures to find trapped in amber, we never would have expected a snail.

Using a newly developed microscopic technique, scientists have been able to create a detailed, 4D image of early mouse embryo development, down to the single cells involved – a fascinating look into the very first stages of life for mammals.

When you push the button on a laser pointer, its entire beam seems to appear instantaneously. In reality, though, the photons shoot out like water from a hose, just at a speed too fast to see.

It's been several months since the late Stephen Hawking passed away, but posthumous writings by the groundbreaking scientist show the great man still had much more to tell us.

A wee baby star at the tender age of just 2 million years has revealed itself to be quite the precocious little cosmic object.

Last week, NASA astronaut Air Force Colonel Nick Hague faced death as he and his commander, Alexei Ovchinin, plummeted to Earth following an aborted Soyuz launch.

There's a lot of stuff out there in the dark, far-flung reaches of the early Universe that we're only just starting to discover. But this one's a real doozy - the early formation of a huge supercluster of galaxies, located 11 billion light-years aw

In January last year, a rocket carrying a tiny chip packed with rubidium-87 atoms was launched more than 200 kilometres (124 miles) above the planet's surface. The mission was brief, affording just six minutes of microgravity at its height.
