The Earth is inhabited by millions of different life forms, and all have been connected through common ancestry in The Tree of Life. The Tree describes the diversity and interconnectedness of all living things on Earth. This video shows the current research that is being done to fully discover the Tree of Life.

Having explored the wonders of the solar system, Professor Brian Cox steps boldly on to an even bigger stage – the universe.
Who are we? Where do we come from? For thousands of years humanity has turned to religion and myth for answers to these enduring questions. But in this series, Brian presents a different set of answers – answers provided by science.
Episode 1: Destiny
The latest COSMIC JOURNEYS episode in 1080p. Where would you look to find Extraterrestrial Life? What planets are likely to have conditions that might spawn life? And what makes Earth special? So far, in this age of planet hunting, we’ve yet to find anything like our solar system… with rocky inner planets in neat circular orbits, and evenly spaced gas giants on the periphery.
Instead, astronomers have glimpsed a diverse planetary zoo, with giant planets in wide orbits around their parent stars, others that swing in so close they leave a comet-like tail, or molten rocky worlds emblazoned with oceans of lava. These finds have added new complexity to theories of how solar systems emerge in the birth of a star…..
Sweet.. I want to go.. somehow
– ScienceDaily (Feb. 2, 2011) — NASA’s Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet’s surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun.
Candidates require follow-up observations to verify they are actual planets. Kepler also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system.
“In one generation we have gone from extraterrestrial planets being a mainstay of science fiction, to the present, where Kepler has helped turn science fiction into today’s reality,” said NASA Administrator Charles Bolden. “These discoveries underscore the importance of NASA’s science missions, which consistently increase understanding of our place in the cosmos.” Read more

The fact that we’ve found a habitable planet candidate so soon after starting our search has important implications for the number of habitable planets that may exist in our galaxy – which was estimated to be around 10 billion.
Having found Gliese 581g so soon though, may mean one of two things. Either we were very lucky, or there are more planets out there than we thought. Based on this discovery, it’s possible that we may have meny more habitable planets than originally thought.
Perhaps 20 to 30 billion stars in our galaxy may have conditions suitable for life.
Damn it… busy day for me… Hey enjoy this amazing intro… 64k the .exe; Fucking magic… my avatar is ~40K
P.S. Pump up the volume… !
Bonus in context: Stephen Hawing predicts the end of humanity.. again… But hey, one thing is true, if we don’t get our asses of this planet, we are going to be extinct… one “fine” day; No bible will save us, no religion can save humanity… only science can…
