Whether it's a romantic getaway to the breathtaking canyons of Mars or the ultimate vacation in Jupiter's magnetic field, National Geographic Channel brings you the ultimate in adventure travel, but it is not for the faint-hearted.

Whether it's a romantic getaway to the breathtaking canyons of Mars or the ultimate vacation in Jupiter's magnetic field, National Geographic Channel brings you the ultimate in adventure travel, but it is not for the faint-hearted. Today's super space traveller must endure drastic climates that shift from 450 degrees celsius in the sun to minus 170 celsius in the shade, crushing gravity, acid smog, and blistering radiation. From Jupiter's churning red eye to Saturn's glittering rings, the sights are out of this world. Blast-off with A Traveller's Guide to The Planets, the ultimate travel guide to the Solar System.

Documents the construction of the cutting-edge Discovery Channel Telescope, based in the Lowell Observatory in Flagstaff, Arizona, from conception to first light.

The invention of the telescope has been by far the most revolutionary development in the history of astronomy. For thousands of years, astronomers had to rely on their eyes in unraveling the mysteries of the Universe. Then, 400 years ago, something entirely new happened: Galileo turned a homemade arrangement of magnifying glasses to the skies. The telescope revealed a wealth of astronomical riches, and led to a dramatic increase of knowledge about the wider world we live in.

90 million miles away from us is the power that shapes our world - the Sun. We see it shine in the sky above us, but beyond our sight something dramatic is happening - the Sun is going into overdrive. It's more active now that it's been for a decade, sending eruptions of super-heated plasma and vast waves of radiation towards our planet. With the potential to disrupt our lives in dramatic ways.

Uncover clues about the origins of our galaxy with a team of astronomers and scientists as they strive to locate a strange presence hidden deep in the core of the galaxy. Learn how this mysterious realm harbors clues to the origin of the world and probes the future course of our galaxy and universe.

All good travel guides need a map, and the team unveil the most detailed 3D map of the Milky Way ever produced. A map that reveals that there may be 50 per cent more stars in the galaxy than we previously thought. American astronomer Neil deGrasse Tyson gives us a guided tour of the strangest stars we have ever observed, and we discover that the Milky Way may already be colliding with our neighbouring galaxy, Andromeda.

The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look up at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars’ worth of elements like iron, nickel, and platinum.

Scientists and engineers who built the world's largest solar telescope and launched the first solar probe into space help predict and prepare the planet for solar storms.
