When a strange alien object is discovered speeding through our solar system, experts race to uncover if it's real evidence of extraterrestrial contact or a deadly asteroid on a collision course with planet earth.
Voyager has had a profound effect on our knowledge of the cosmos. Its mission was supposed to last five years but remains ongoing, fundamentally changing our understanding of the solar system. Featuring contributions from key scientists, we’ll explore what’s been achieved and what happens next.

This is the story of the most extraordinary journey in human exploration, the Voyager space mission. In 1977 two unmanned spacecraft were launched by NASA, heading for distant worlds. It would be the first time any man-made object would ever visit the farthest planets of the solar system - Jupiter, Saturn, Neptune and Uranus. On the way the Voyagers would be bombarded by space dust, fried by radiation and discover many of the remarkable wonders of the solar system. Now, at the end of 2012, 35 years and 11 billion miles later, they are leaving the area of the sun's influence. As they journey out into the galaxy beyond they carry a message from Earth, a golden record bolted to the side of each craft describing our civilisation in case of discovery by another. This is the definitive account of the most intrepid explorers in Earth's history.

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular. Galaxies can collide, and grow in size by eating each other.
It was 30 years ago that the first space shuttle, Columbia, was launched. It was such a triumph of technology, engineering and organization that it's easy to forget the programme was primarily the product of an economy drive. The disposable Apollo missions had cost billions. A reusable craft was deemed more expedient.
