Surprising new results from the Juno mission may us help work out what's going on at Saturn and other gas giants, too.
Planetary protection protocols try to make sure we don't seed places like Mars with life from our planet. An astrobiologist argues they're misguided – especially with human astronauts on the horizon.
Will humans ever live on Mars? Whoever it is to get there first will benefit from the experiences of those who stayed in simulated Martian missions here on Earth.
Scientists discover rare molecules on Titan which suggests it's creating the building blocks of life.
The volcanoes would be a great place t to search for fossilised microbes.
One of the best ways to find out the challenges of living on Mars is to simulate living on another planet here on Earth. So what's it like to spend several months living the Martian life?
We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
Recent high-profile disappointments make it tempting to this our efforts to explore Mars are cursed. But landing anywhere in space is hard – not least on the Red Planet.
The red hue of the moon during a total lunar eclipse gives astronomers at cue on how to find out more about the planets being discovered around other stars.
More than three thousand planets have been found orbiting other stars in our galaxy. The challenge now is to find out more about these planets.
The discovery of carbon in the form of graphite on the surface of Mercury helps explain the mystery of why the tiny planet is so unusually dark.
A new planet in our solar system? Let's get direct proof before we start naming it.
Studying the young, Jupiter-sized planet 51 Eridani b opens a window into our solar system's past.
Photos from the spacecraft's close approach are dazzling. They and other data from the mission will fill in some of the blanks about Pluto and provide a snapshot of the infant solar system.
New Horizons mission members have worked on the project for even longer than it's taken the spacecraft to get to Pluto. They've planned, built and researched – and now their efforts are paying off.
Jupiter's moon Europa is one of the most enticing objects in our solar system, and a future NASA mission may help reveal whether it is a suitable for life.
The moon might harbor bits of the Earth that blasted off our planet billions of years ago. These lunar time capsules could hold secrets about conditions here at home back when life was first emerging.
