Is there anyone out there? Astronomers have been pointing their radio telescopes at the skies for decades trying to pick up alien signals, so far without success. But now there's a new way of looking for aliens. Hitch a ride with Dr Graham Philips as he joins astronomers trawling through the galaxy looking for signs of extra-terrestrial intelligence.

This series traces the history of classic video games, featuring insights from the innovators who brought these worlds and characters to life. In the first episode, Space Invaders and Pac-Man lead an arcade craze, while Atari's cartridge system dominates home gaming until high-profile failure sparks a downfall.

The International Space Station is the ultimate extreme home. Costing $150 billion, it is the most expensive structure humans have ever built, in the most inhospitable environment known to man, with no air food or water. Assembled at 250 miles above the earth, it's an epic engineering challenge. We're going to take it apart and uncover what's going on inside the ISS.
Its superstructure secrets will help our species reach other planets and beyond. Using photo-real computer graphics, we take it apart to uncover the extraordinary innovations that enable it to support life in the deadly vacuum of space.

Blowing your mind, that's what Doctor Who's all about. What makes it all so fun is that while all this crazy science fiction is going on, there's actual facts. You've got space travel, you've got time travel, you've got regeneration. These are all the powerful themes of Doctor Who. And they're also the things that drive science forward.

Commander Stephen Hawking and his space ship the SS Hawking encounter an alien A.I., then race to the edge of the universe, and plunge into an alternate Earth. It's an epic quest to discover the secret of the universe: The Theory of Everything. RIP. Stephen Hawking.

Follow astronaut Scott Kelly’s record-breaking 12-month mission on the International Space Station, from launch to landing, as NASA charts the effects of long-duration spaceflight. A Russian Soyuz spacecraft carried Scott Kelly of NASA and Mikhail Kornienko of Roscosmos to the space station for the longest space mission ever assigned to a NASA astronaut". The expedition provided important insights into operational and scientific areas in human research in space and on Earth. Integrated scientific investigations between NASA and Roscosmos will combine resources to improve data sharing among space medical and human research communities, as well as help inform current assessments of crew performance and health and better determine and validate countermeasures to reduce the risks associated with future exploration as NASA plans for missions around the moon, to an asteroid and eventually to Mars.
