Russian Meteor Strike 2013

January 10, 2014 - [ 1 part ]
The site of impact of an enormous comet, found in North America, has enabled scientists to model its catastrophic collision with the Earth, an event alleged to have wiped out the dinosaurs. What happened when the resulting fireball caused billions of tons of sulphuric acid to be released into the atmosphere - and could it ever happen again? Horizon reaches back in time and reconstructs how, in a brief moment, the fate of millions of species was sealed: from the new-found fossil 'horizon of death', to scientists modelling the blast itself; a million times stronger than the world's combined nuclear arsenals. Startling graphics reveal how in 30 seconds North America was scoured by a fireball. Within an hour the world was aflame. And new evidence shows that the asteroid chanced on the worst possible site on Earth to strike. It hit unique sulphate-rich rocks, vaporised them, and kicked billions of tons of sulphuric acid into the atmosphere.

Academy Award-winning actor and space enthusiast Morgan Freeman executive produces,hosts and narrates this exploration of the greatest mysteries of the universe. This new series, produced by Freeman's Revelations Entertainment, seeks the answers to the big questions: Are we alone? Where did we come from? Is there life on other planets? From the latest work at NASA and private enterprise facilities to the latest theories from futurists and physicists, this series looks at black holes, colonizing the planets, string theory and more. Science Channel invites viewers on the journey as Morgan Freeman picks up where Carl Sagan's 'Cosmos' left off and explores the new frontiers of what is beyond earth.

The CGI or computer animated drama/documentary takes place on Darwin IV, a planet 6.5 light years from earth, with 2 suns and 60% of Earth's gravity. Having identified Darwin as a world that could support life, Earth sends a pilot mission consisting of the Mothership Von Braun and three probes: Balboa, Da Vinci, and Newton. This robotic fleet is responsible for finding and assessing any life forms on Darwin IV. Initially, the expectation is to find microscopic life, but the probes soon find themselves in the middle of a developed ecosystem teeming with diversity of life of all sizes. The drama on Darwin IV is motivated by real science missions, such as the NASA Origins Program and the NASA / JPL Planet-Finder Mission, as well as the European Space Agency's Darwin Project. 'Alien Planet ' is a cosmic expedition along side Stephen Hawking, Michio Kaku, Jack Horner, Craig Venter, and George Lucas...

Documentary about End of the Earth, Sun and universe. The future of the planet is closely tied to that of the Sun. As a result of the steady accumulation of helium at the Sun's core, the star's total luminosity will slowly increase. The luminosity of the Sun will grow by 10% over the next 1.1 Gyr (1.1 billion years) and by 40% over the next 3.5 Gyr.Climate models indicate that the rise in radiation reaching the Earth is likely to have dire consequences, including the loss of the planet's oceans. The Earth's increasing surface temperature will accelerate the inorganic CO2 cycle, reducing its concentration to levels lethally low for plants (10 ppm for C4 photosynthesis) in approximately 500 million to 900 million years. The lack of vegetation will result in the loss of oxygen in the atmosphere, so animal life will become extinct within several million more years.After another billion years all surface water will have disappeared and the mean global temperature will reach 70 °C. The Earth is expected to be effectively habitable for about another 500 million years from that point,lthough this may be extended up to 2.3 billion years if the nitrogen is removed from the atmosphere.Even if the Sun were eternal and stable, the continued internal cooling of the Earth would result in a loss of much of its CO2 due to reduced volcanism,nd 35% of the water in the oceans would descend to the mantle due to reduced steam venting from mid-ocean ridges.The Sun, as part of its evolution, will become a red giant in about 5 Gyr. Models predict that the Sun will expand out to about 250 times its present radius, roughly 1 AU (150,000,000 km). Earth's fate is less clear. As a red giant, the Sun will lose roughly 30% of its mass, so, without tidal effects, the Earth will move to an orbit 1.7 AU (250,000,000 km) from the Sun when the star reaches it maximum radius. The planet was therefore initially expected to escape envelopment by the expanded Sun's sparse outer atmosphere, though most, if not all, remaining life would have been destroyed by the Sun's increased luminosity (peaking at about 5000 times its present level).However, a more recent simulation indicates that Earth's orbit will decay due to tidal effects and drag, causing it to enter the red giant Sun's atmosphere and be vaporized.Possible alternatives to this fate include the purposeful displacement of an asteroid from the Kuiper belt, which would repeatedly fly close enough to Earth as to enlarge its orbit, thereby preventing the overheating of its surface. The lifespan of the biosphere could thereby be extended by 5 billion years.
