The US Federal Aviation Administration (FAA) has just awarded Virginal Galactic their first operating license, allowing them to start using their SpaceShipTwo craft for commercial use - as soon as certain guidelines are met. This means that the company - owned by billionaire Richard Branson - will soon be able to shuttle paying passengers into space.

Other than making the flights legal, the license dictates the conditions required before Virgin Galactic can actually let any passengers on board SpaceShipTwo, which will be carried by White Knight Two (below) roughly 99 kilometres (62 miles) into the sky.


Once everything is squared away with the FAA, SpaceShipTwo - a spacecraft designed to hold two pilots and six passengers - will hitch a ride w ...

Cosmologists have formulated a new theory that suggest the universe didn’t start with the Big Bang. They believe the birth of the universe happened after a 4D star collapsed into a black hole and ejected debris, which helps explain why the universe has an almost uniform temperature.

Flames look a little different in space. On Earth, gravity causes a candle flame to be teardrop-shaped, and carries soot to the flame's tip, making it yellow. In microgravity, where these forces are absent, the flame is spherical, soot-free, and blue.

The strangest moon in the Solar System is bright yellow. Taken by the Galileo spacecraft, this image shows Jupiter's moon, Io, and its incredibly bright colours derived from sulphur and molten silicate rock. Io is covered in volcanoes that are so active, they effectively turn the whole moon inside out. And some of Io's volcanic lava is so hot, it glows in the dark.

Desolate, frozen and black as coal - welcome to the surface of Comet 67P/Churyumov-Gerasimenko. This is one of the closest colour images ever of a comet, taken from just 29 kilometres away by the European Space Agency's Rosetta spacecraft. Rosetta will soon land on this rugged surface.

NASA scientists have nominated eight potential new targets for a 2020 Mars mission. They're focusing on ancient river deltas and hot springs as sites that have the best chance of preserving signs of life on the red planet. New sites can still be considered, and mission engineers have yet to weigh in on the technical feasibility of landing the rover in the nominated sites.

This is supernova remnant W49B. It is located about 26,000 light-years from Earth, and as we see it it is approximately 1,000 years old. Compared to other supernova remnants of similar type and age, it is distorted in an usual way. Astronomers believe that it is distorted because it is in the infant stages of of forming a black hole -- the very first time this has been observed.

Architectural and engineering firm Shimizu plans to solve Earth's climate crisis by building a band of solar panels 400 kilometres wide along the entire 11,000-kilometre equator of the Moon. The energy generated will be beamed back to Earth in the form of microwaves and converted into electricity at ground stations. The team hopes to start building the "Luna Ring" from Moon materials in 2035.
