Earth From Space
(HD 1080p / Nova)
The groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth.

National Geographic: The Story of Earth
The Earth might seem solid beneath our feet but five billion years ago there was no sign of the planet we call home. Instead there was only a new star and a cloud of dust in our solar system. Over millions of years, a series of violent changes led to the formation of our world and, eventually, the creation of life.
In this photorealistic CGI epic, see how a boiling ball of rock transformed into the blue planet we know today. Explore every aspect of our world; learn how water first arrived on Earth, discover the vital role oxygen played as life forms began to evolve, and find out how land mammals evolved into dinosaurs and other giant beasts, before becoming extinct 65 million years ago.
Cutting-edge imagery also reveals how humans first began to walk on two feet and looks into the future to see what may be in store for our home over the next five billion years.

Three Years of Sun in Three Minutes
In the three years since it first provided images of the sun in the spring of 2010, NASA's Solar Dynamics Observatory (SDO) has had virtually unbroken coverage of the sun's rise toward solar maximum, the peak of solar activity in its regular 11-year cycle. This video shows those three years of the sun at a pace of two images per day.
SDO's Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 Angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin. In this wavelength it is easy to see the sun's 25-day rotation as well as how solar activity has increased over three years.
During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits the Earth at 6,876 miles per hour and the Earth orbits the sun at 67,062 miles per hour.
Such stability is crucial for scientists, who use SDO to learn more about our closest star. These images have regularly caught solar flares and coronal mass ejections in the act, types of space weather that can send radiation and solar material toward Earth and interfere with satellites in space. SDO's glimpses into the violent dance on the sun help scientists understand what causes these giant explosions -- with the hopes of some day improving our ability to predict this space weather.
There are several noteworthy events that appear briefly in this video. They include the two partial eclipses of the sun by the moon, two roll maneuvers, the largest flare of this solar cycle, comet Lovejoy, and the transit of Venus. The specific time for each event is listed below, but a sharp-eyed observer may see some while the video is playing.
00:30;24 Partial eclipse by the moon
00:31;16 Roll maneuver
01:11;02 August 9, 2011 X6.9 Flare, currently the largest of this solar cycle
01:28;07 Comet Lovejoy, December 15, 2011
01:42;29 Roll Maneuver
01:51;07 Transit of Venus, June 5, 2012
02:28;13 Partial eclipse by the moon

Plains Milky Way
During the month of May, I shot Milky Way timelapse in central South Dakota, when I had the time, and the weather cooperated. The biggest challenge was cloudy nights and the wind. There were very few nights, when I could shoot, that were perfectly clear, and often the wind was blowing 25mph +. That made it hard to get the shots I wanted. I kept most of the shots low to the ground, so the wind wouldn't catch the setup and cause camera shake, or blow it over. I used a Stage Zero Dolly on the dolly shots and a "Milapse" mount on the panning ones.
Canon 60D and T2i
Tokina 11-16
Sigma 20mm F1.8
Tamron 17-50
Dynamic Perception Stage Zero Dolly http://www.dynamicperception.com/#oid...
Shot in RAW format, the Milky Way shots were 30 seconds exposure F2.8 or F1.8 with 3 second interval between shots, for 3-4 hours run time. ISO 1600
Ten seconds of the video is about 2 hours 20 minutes in real time.
Simon Wilkinson from http://www.thebluemask.com scored the soundtrack "Exodus" for the video
