An artistic concept of Alien Life

These bizarre jellyfish-like beings were dreamt up by a British scientist as an example of life 'not as we know it'.

This is what evolution might have come up with on a world such as Saturn's moon Titan, Dr Maggie Alderin-Pocock believes.

She envisages creatures that float through clouds of methane, scooping chemical nutrients into their gaping mouths.

The aliens keep themselves aloft by means of dangling onion-like buoyancy bags, and communicate with pulses of light.

ESA Euronews: Dragon and the Private Space - YouTube

Boldly going where no private company has gone before.

On 25 May 2012, Dragon, the first commercial spacecraft berthed with the International Space Station.

A private company achieved something only national agencies have ever done before: flying and recovering an orbital craft.

With private companies launching their own spaceships and designing their own orbital stations, it's the dawn of commercial spacefaring.

We talk to people involved in that development and we explore the world's first commercial spaceport.
