Earth from Space
“A time-lapse of Planet Earth, created from images produced by the geostationary Electro-L Weather Satellite. The images were obtained beginning on May 14th, and end on May 20th. The images are the largest whole disk images of our planet, each image is 121 megapixels, and the resolution is 1 kilometer per pixel. They are taken every half hour, and have been interpolated (smoothed) to create this video. The images are taken in four different wavelengths of light, three visible, and one infrared. The infrared light is reflected by forests and vegetation, which appear orange in these images.”
The Hubble Ultra Deep Field in 3D
Fascinating video about an experiment they did with the Hubble telescope. They pointed the telescope in to a dark, empty part of space about the size of a small grain 0f sand and then left the lens open for 10+ days. This video shows and talks about what they found. In that incredibly small window they found tens of thousands of galaxies each of which contains hundreds of billions of stars. It really gives a glimpse of a perspective of how big and infinite the universe is.
