Researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune.

Researchers developed a Martian concrete using materials naturally found on the planet. The high-strength concrete can be quickly created and is durable enough to withstand meteorite impacts - a key element needed to create viable shelters for humans.

How are asteroids and planets formed from stony particles? This question is being explored in an experiment by scientists who have developed beads made of a special type of glass. They form the composition of the rock particles as naturally as possible on a small scale.

The International Space Station is the longest-running continuously inhabited human outpost in space - this year it celebrated its 15th anniversary. As the ISS orbits the Earth it is essentially in a state of free fall, counteracting the Earth's gravity and providing an ideal platform for science in space.
