Real World: How the Hubble Telescope Is Powered in Space

admin — Sat, 17 Apr 2010 12:20:16 +0000

In this NASA eClips video segment learn how NASA uses light from the sun to make electricity in order to keep the Hubble Space Telescope powered in space. Learn how batteries store the energy needed to keep the Hubble powered when it is in orbit at night and how solar panels help keep it powered when it orbits in the light. Demonstrations using graphs and mathematical equations help explain what it takes to keep the Hubble powered while in orbit around the Earth.

Against the stunning backdrop of the glaciers of Alaska, Brian reveals his fourth Wonder. Saturn’s moon Titan is shrouded by a murky, thick atmosphere. He reveals that below the clouds lies a magical world. Titan is the only place beyond Earth where we’ve found liquid pooling on the surface in vast lakes, as big as the Caspian Sea, but the lakes of Titan are filled with a mysterious liquid, and are quite unlike anything on Earth.

SOLAR SYSTEM HD

admin — Thu, 18 Mar 2010 16:18:04 +0000

I created this animation using 3ds max 3d modeling and particle sytems.
My fascination with our universe goes way back to my childhood and I’m sure many of you out there share the same interest.
Please note that this video wasn’t intended to to compare planet/sun size but just a visual representation of the solar system where planets textures are visible for the inner and outer planets.
Part 2 of this Video is now also available.
I hope you enjoy it
