Have planet hunters finally found proof of other Earth like worlds? Astronomers have now discovered over two hundred alien worlds, beyond our solar system, that were unknown just a decade ago. Discover planets that rage with fiery hurricanes and bizarre planets covered by water so dense that it forms a kind of hot ice. Among these weird worlds, Earth actually seems like the oddball.

Today, we know black holes exist, and now scientists are trying to confirm that other holes lurk in hyperspace. Our infinite cosmos could contain a variety of "holes" such as black, white, "mini" and wormholes. White holes are the reverse of black holes; instead of matter being sucked into it, matter is ejected out. Wormholes are gateways in the fabric of space and time. They are included in Einstein's field equations as possibilities for their existence. Neither white holes nor wormholes have ever been found. Learn about new discoveries including, colliding binary black holes, intermediate black holes and manufacturing mini black holes.

For thousands of years, mankind has found comfort in its presence. It's been a lantern for nighttime travellers, a timekeeper for farmers and a location finder for sailors at sea. For some cultures, it's even been a god. It's the only cosmic body ever visited by human beings. From afar, the Moon's luminance has captivated us since the beginning of time. And a closer look at the beacon in the dark sky reveals an ever-present source of myth, intrigue, controversy and unsolved mysteries. The field of science may cast an empirical light on some things about the Universe, but lunar experts are the first to admit they don't have all the answers when it comes to our Moon. This episode explores the theories behind Lunar Transient Phenomena that have left scientists stumped for centuries; takes to the Canadian waters to see how the Moon effects our planet through tides; and dusts off some age-old myths and weighs arguments that without our Moon, humanity may not even exist.

We used to think that Earth was at the centre of the universe, but now we know we're not even at the centre of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic centre of our galaxy. Within the Milky Way can be found the debris of old, dying stars fuelling the birth of new stars and at the galactic centre hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Travel from the inner solar system to the Kuiper Belt and explore the moons surrounding the planets of the solar system. Many of these moons that were once unknown are now on the cutting edge of astronomical study. Some burst with volcanic fury another spews icy geysers and others offer the possibility of alien life. Are these strange worlds simply hostile environments unfit for humans or do other possibilities exist? Cutting-edge computer graphics are used to bring the universe down to earth and to imagine what kind of life forms might evolve in alien atmospheres.

'Dinosaurs: Giants of Patagonia' Following Pr Rodolfo Coria, a world-reknown Argentinian paleontologist, we visit sites of major discoveries he has contributed to in Patagonia and travel back in time to see these amazing beasts come to life in 3D. Patagonia has given us the largest living animal to ever walk the Earth: the titanesque plant-eating Argentinosaur, and its nemesis, the Giganotosaur, a bipedal carnivore that could easily challenge the famous T-Rex.
