All five five planets visible to the naked-eye are on show in the night skies over Australia, and a Blood Moon on the way too.
Each meteorite is a piece of the puzzle to understanding our solar system.
Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
Following NASA’s latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
NASA and ESA have signed a letter of intent to collect samples from Mars and return them to Earth.
What is Mars made of? We hear from a scientist who will be part of the team analysing ‘marsquake’ seismic data and orbital imagery from the InSight mission to the red planet.
Cosmic radiation is much higher today than it was during the Apollo era.
The InSight Lander mission to Mars is preparing for launch in May 2018. But there are seven (or eight) other planets to explore: why have we such a hang up on Mars?
The launch of Elon Musk’s Falcon Heavy rocket is undoubtedly a spectacular feat of engineering - but the release of a sports car into orbit also says something about our values as human beings.
LED lights can actually improve upon the sun and help grow plants in space. A Canadian team of researchers is helping to refine and perfect LED technology.
If we find microbes on Mars, it will be difficult to exclude the possibility that we have accidentally brought them there from Earth.
The race may be on to send humans to live on Mars, but is it worth the effort – and the spend – when we have our own problems to deal with on Earth.
Clay on early Mars could have formed under hot and steamy conditions, challenging the idea that it was created just like that on Earth.
Simulations in a special chamber suggest how the Mars landscape could have been shaped under certain conditions.
Future Mars colonists may want to form their own legal system. What would stop them?
