Given its distance from the Sun, and the nature of its composition, Neptune is renowned for being the coldest planet in our Solar System

The difference between lava and magma, which is rather important when it comes to volcanic activity and geology, is just a question of location

The focus of space exploration, and exploitation, has long been the technologies required. But there's a legal aspect to space exploration, too.

A a distant gas giant, Jupiter takes a considerable amount of time to orbit our Sun. In act, a single year on Jupiter is equal to almost 12 years on Earth

The Hubble Space Telescope gets in the act with a spectacular new close-up of Mars taken just days before opposition. We also look at what you'll be able to see both with the naked eye and through the telescope.

Orbital ATK has unveiled a practical new proposal to build a near term man-tended outpost in lunar orbit that could launch by 2020 and be operational in time for a lunar link-up with NASA's Orion crew module during its maiden mission, when American astronauts finally return to the Moon's vicinity in 2021 - thus advancing America's next giant leap in human exploration of deep space.

When our Venus (aka. "Earth's Twin") orbits between the Earth and the Sun (i.e. during an interior conjunction), it becomes Earth's closest neighbor

With Pluto in its rear-view mirror, New Horizons is heading towards its next target, and sending back valuable science on its way.

Since ancient times, scientists have debated the true nature of light. Despite the progress we've made, there are still mysteries left to be resolved

The next Orion crew module in line to launch to space on NASA's Exploration Mission 1 (EM-1) has passed a critical series of proof pressure tests which confirm the effectiveness of the welds holding the spacecraft structure together.

Scientists in Australia have found evidence of an enormous asteroid impact about 3.5 billion years ago. But the site of that impact remains a mystery.

According to a recent study from the Carl Sagan Institute, aging red giant stars could still have habitable zones that create life on its distant planets

Rolling rolling rolling! Yee-haw! 2 By Sea, 1 By Land. The 3rd recovered Falcon 9 booster has joined her siblings inside SpaceX's gleaming new processing hangar, laying side-by-side at Launch Complex 39A at NASA's Kennedy Space Center (KSC) in Florida.

Pluto and Haumea have long been thought of as cousins. But a new study highlights Haumea's lack of small, icy moons, and has astronomers puzzled.

Simply put, air resistance (aka. drag) describes the forces that act opposite to an object's velocity as it travels through an atmosphere

In the constellation of Ophiuchus lies the M14 globular cluster, a loose concentration of stars spanning 100 light years, 300,000 light-years from Earth

Thanks to astronaut Tim Peake, people here on Earth have been treated for the first time to an image of what a chipped window aboard the ISS looks like!
