3D printing has the potential to go places, like the moon for instance. The European Space Agency (ESA) has commissioned several architecture firms to see if buildings can be 3D printed on the moon using lunar soil.

Researchers have found evidence of the world that crashed into the Earth billions of years ago to form the Moon.

Analysis of lunar rock brought back by Apollo astronauts shows traces of the "planet" called Theia.

The researchers claim that their discovery confirms the theory that the Moon was created by just such a cataclysmic collision.

The study has been published in the journal Science.

Jupiter's moon Ganymede is seen in transit over the great red spot. It does look like it is staring at us.

Pluto, a distant icy dwarf planet, orbits the Sun 29 times farther out than the Earth and has estimated surface temperatures of -380 degrees Fahrenheit (-229 degrees Celsius). These frigid temperatures are far too cold to allow liquid water on Pluto's surface. Its location and small size make it very difficult to observe; however, with NASA's New Horizons mission slated to reach the distant world next year, scientists hope to map Pluto and its moons in great detail.

Current models predict one moon in particular, Charon, is of great interest to study. The models indicate Charon has surface fractures, indicative of a possible subsurface ocean. Further analysis is needed to determine in the moon's interior is warm enough to support liquid water.

We all know Usain Bolt is one of the fastest people on Earth. Now, students have shown his superhuman speeds would actually allow him to fly like a bird on one of Saturn's moons while wearing a wingsuit.

The world-record holding sprinter has reached top speeds of 12.27 metres per second, which would be fast enough for him to take off on Titan while wearing a regular wingsuit.

Theoretically, the Olympic athlete would then be able to soar above the planet – without any need for propulsion.

The companies want to put a 2-meter radio antenna along with a smaller optical telescope on a lunar peak, most likely the 5-km-high rim of a crater called Malapert. From this position, both telescopes could view the center of our Milky Way galaxy with unprecedented clarity because they wouldn't be subjected to our atmosphere's hazy interference. The moon would also block them from radio and other electromagnetic noise created by modern civilization. Astronomers have long proposed putting similar telescopes on the moon's far side – which faces permanently away from our planet – because the pictures could exceed anything produced by the best terrestrial or even space-based instruments.
