We know more about life in space – and at home – than ever before. But what do we do with that knowledge?
The next five years will see a resurgence in lunar exploration, driven both by idealism and an economic incentive.
Nasa and ESA teamed together to build a telescope. But unknown to them, that telescope was about to revolutionise our understanding of the universe, both scientifically and visually.
Travelling at close to the speed of light may be necessary for humans to colonise the galaxy, but the maths show it'd be like flying through a cloud of bombs - but also that we should notice the explosions here on Earth, if any other civilisation has managed the feat.
It's increasingly clear that the Solar System is more life-friendly than we'd previously suspected.
So much for being special.
Mars' moons are unusual in the Solar System - for their size, shape and colour from their parent planet. Where did they come from? We've got some clues to work with.
Secret oceans on the moons Enceladus and Ganymede were discovered within days of each other, reshaping our belief that the Earth is the Solar System's most watery, life-friendly habitat.
Despite Einstein and Hawking, we still know very little about black holes.
With only days to go before the first probe goes into orbit around this surprisingly interesting dwarf planet, further mysteries - including two strange bright spots in a crater - are coming into focus.
The Red Planet is bad for humans in all kinds of ways, and being first there may be little consolation if you die before you even reach the surface.
If only politics worked half as well as space exploration.
Eureka! We've found Beagle2 – now, where did Philae go?
Ian Stewart shows how maths is changing cosmology, and explains why the best way to reach a comet near Mars is to go round the back of the sun.

Reflecting heat back into space, seeding the ocean with iron, simulating the effects of volcanic dust - the problem with thinking big about fixing the climate is that the massive risks are far more expensive than the known costs of simply not screwing the planet up in the first place.
The ESA wants to test a 3D printer in orbit because this is likely to be the best place and method of building the equipment that will take us further out.
Governments are setting their sights on missions to Mars and the moon but private companies are focused on shorter excursions into space. Their motivation is simple: there’s money in it.
The latest iteration of Icke’s meta-narrative involves the Archons, an ancient race of reptilian psychopaths who have hijacked our perception of reality in the manner of The Matrix.
A team from MIT estimated how long it would take for the mission to experience its first fatality. The answer: 68 days. The second group would arrive to find the first pioneers had been dead for more than a year and a half.
Mars has become the destination of choice for ambitious space agencies and nations. Now India is among that group.
Either our understanding of how stars form needs a big overhaul, or one of the current missions of the European Space Agency could turn out to be something of a white elephant.
It’s increasingly becoming clear that space is a more hospitable environment than was assumed.
This ball of rock and ice formed at the same time as our solar system and should, if predictions are correct, contain complex organic molecules, the same stuff as terrestrial life is made from.
After a ten year chase, Rosetta became the first ever spacecraft to intercept and go into orbit around a comet - and over the next 18 months will begin searching for clues left over from the earliest moments of our Solar System.
Erica Wagner on a new biography of the space pioneer.
The United Arab Emirates now has its own space agency, and plans to launch a mission to Mars by 2021.
Hopefully, we'll soon be launching a mission to Mars from the UK.
Gravity is pathetic and so is our understanding of it.
The European Space Agency's Gaia telescope is so powerful, it see stars with power akin to measuring the width of a human hair at a distance of 500 km.
