Russian Satellite Elektro-L took this picture of Earth. The detail is stunning and the color looks like an artist added it (even though it wasn't). Below is the post from Universe Today where I found the picture.





Unlike most satellite images of Earth, this one was not assembled from multiple swath scans or digitally projected onto a globe model — it’s the full disk of our planet in captured as a single, enormous 121 megapixel image, acquired by Russia’s Elektro-L weather-forecasting satellite.


Like NASA’s GOES satellites, Elektro-L is parked in a geostationary orbit approximately 36,000 km (22,300 miles) above our planet. Unlike NASA’s satellites, however, Elektro-L captures images in near-infrared as well as visible wavelengths, providing detail about not only cloud movement but also vegetation variations. Its wide-angle Multichannel Scanning Unit (MSU) takes images every 15-30 minutes, showing the same viewpoint of Earth across progressive times of the day.


At a resolution of 0.62 miles per pixel, full-size Elektro-L images are some of the most detailed images of Earth acquired by a weather satellite.


A second Elektro-L satellite is anticipated to launch in 2013.Launched aboard a Zenit rocket on January 20, 2011, Elektro-L was the first major spacecraft to be developed in post-Soviet Russia. Parked over Earth at 76 degrees east longitude, Elektro-L provides local and global weather forecasting and analysis of ocean conditions, as well as “space weather” monitoring — measurements of solar radiation and how it interacts with Earth’s magnetic field. Its initial lifespan is projected to be ten years.

More impressive ground based images of the STS-133 mission, this time, Amateur astronomer Ralf Vandebergh of the Netherlands took images during one of the spacewalks for the mission, and likely captured astronaut Steve Bowen at work on the end of the Canadarm 2! Click on the image above, or go to Ralf’s website for a better view and more information.

Another amateur astronomer from the UK, Martin Lewis also took similar images of the spacewalk.
Ralf uses a 10 inch Newtonian telescope with a videocam eyepiece, and manually tracks the ISS and other objects across the sky. He takes most of his images in color to obtain the maximum possible information of the objects.

He took a similar image about 2 years ago of astronaut Joe Acaba on an EVA outside the ISS in March of 2009, which was featured on Astronomy Picture of the Day. He has also taken images of of ISS and Dexter, the special purpose manipulator, or this one of space shuttle Discovery on the STS-131 mission.
