Radiation in space could lead to cognitive decline.
In our efforts to keep peace in space we could learn much from the US-Russian relationship on the International Space Station.
Russian space vessel Progress M-27M is falling towards Earth but what risk does it pose?
Near-Earth orbits are filled with useful satellites, and also flying junk. If we’re not careful they may collide - literally.
Twenty-five years on and the Hubble Space Telescope is still taking some amazing images. But there have been a few glitches over the years, right from day one.
From a big blue marble to a tiny dot in space – reflections on our images of Earth.
Star Trek fans were especially drawn to Leonard Nimoy’s Mr. Spock – who showed many that it “was okay to be a nerd, that even in the future not everyone fit in, or needed to.”
At the winter meeting of the American Astronomical Society earlier this month, the NASA Kepler Space Telescope team announced its 1,000th discovery of a planet outside our solar system. This brings the…
As a headline, “No gas leak on the International Space Station” ranks alongside recent news stories, such as “Mild earthquake in North Texas – no damage reported” and “No-one hurt in bedroom fire”. But…
SpaceX is attempting a huge feat in spacecraft engineering. It is seeking to land the first stage of its Falcon 9-R rocket on a floating platform at sea. Normally this would end up at the bottom of the…
There is no doubt that 2014 was a fantastic year for planetary sciences – the high points were the successful landing of Philae on comet 67P, the discovery of methane by the Curiosity rover on Mars and…
The Theory of Everything is a film about two people who meet at university and fall in love. But what makes it remarkable is that one of them is Professor Stephen Hawking and that when he and Jane Wilde…
NASA has revealed that a whiff of methane has been detected twice in the last couple of years at the Martian surface by the Curiosity Rover. The source of the methane is uncertain. It is not even clear…
After a 24-hour delay due to bad weather, the first test launch of the Orion spacecraft by NASA is underway with the ultimate goal of putting human beings on Mars. Weeks after the landing on a comet by…
The thing everyone seems to talk about with the moon landings is the idea of the whole world stopping to watch. It was a mission that overcame nationalism, it wasn’t “America” putting a man on the moon…
Interstellar has been praised for its attempt to make the “hard science” of astrophysics both accessible and exciting to a popular audience. Through cutting-edge special effects, it takes audiences on…
What’s the betting that Agilkia makes it into the baby name charts in 2015? This romantic, lyrical word is the name of an island in the Egyptian Nile, but it’s also just been given to the patch of Comet…
The recent accident involving Virgin Galactic’s SpaceShipTwo – and the tragic death of one pilot and critical injury of another – highlights the dangers inherent in any type of space flight. It has also…
The final week in October was widely reported as having been disastrous for space exploration. First we had the explosion of the crewless Antares launcher as it lifted off to take provisions to the International…
