It is possible to split water into oxygen and hydrogen gas in zero gravity using sunlight, shows new study.
Cosmic radiation is much higher today than it was during the Apollo era.
It's been reported that astronaut Scott Kelly no longer has the same DNA as his twin brother after spending a year in space.
The students of class 3F at Ferny Grove State School want to know how they get oxygen into the International Space Station.
We’ve only travelled into space in the last century, but humanity’s desire to reach the moon is far from recent.
Dreams of new footprints on the moon are more about domestic politics than foreign policy.
Astronauts traveling to Mars and beyond would face serious psychological challenges. A well-designed media program – based on an old-fashioned schedule – might help make life at least a bit easier.
If you want to live on Mars, you're going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they'll encounter off-planet?
Despite not being able to see them, we know a fair bit about our exoplanet neighbours.
There are loads of applications for 3D printers in space.
To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.
The Astronomer Royal answers some of the world's – and the universe's – biggest questions.
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it's time to figure out what happens to our biology in its absence.
A twin experiment in space can help us prevent diseases on Earth.
Scientists have finally found an Earth-like planet we may actually be able to visit.
Scientists are working out how to grow plants in space, ready to use them as food when we visit other planets.
In theory, astronauts get the equivalent of a lethal x-ray dose during a six-month stay at the ISS. Here's why we don't have to worry too much though.
Former NASA astronaut Ron Garan speaks his mind about space travel, terraforming and religion.
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
