How NASA Creates Those Beautiful Blue Marble Photos of Earth

After NASA published its latest jaw-dropping “Blue Marble” photograph of Earth last month, many of you wondered how “real” the image was. Here’s NASA’s explanation on how their images are created:

The Suomi NPP satellite is in a polar orbit around Earth at an altitude of 512 miles (about 824 kilometers), but the perspective of the new Eastern hemisphere ‘Blue Marble’ is from 7,918 miles (about 12,743 kilometers). NASA scientist Norman Kuring managed to ‘step back’ from Earth to get the big picture by combining data from six different orbits of the Suomi NPP satellite. Or putting it a different way, the satellite flew above this area of Earth six times over an eight hour time period. Norman took those six sets of data and combined them into one image.

So rather than being a composite of multiple images captured from the same perspective, they do in fact map images captured by the satellite onto a 3D sphere.

Blue Marble: A Stunning 64-Megapixel Photograph of Earth

NASA has released another Blue Marble photograph of Earth. It calls this one the “most amazing, highest resolution image of Earth ever”. The image is a composite created from a number of photos of Earth’s surface captured on January 4, 2012, and weighs in at a massive 64-megapixels (8000×8000). You can download the full-res version here. Be warned though — it might crash your browser.

Planets Created by Combining Photos Captured From High Locations

Creating tiny planets by projecting panoramic photographs onto a sphere is something you’ve probably seen before, but Dutch photographer Wouter van Buuren creates his planets a bit differently. rather than shoot panoramas from the ground, van Buuren climbs to the top of towers, cranes, skyscrapers, and bridges and points his camera in every direction below. He then takes the resulting photographs and arranges them into compact worlds.

Jaw-Dropping Time-Lapse Shots of Earth

Between August and October of this year, the crew onboard the International Space Station used a Nikon D3S (at high ISOs) to capture photographs of Earth as they zipped around it at 17,000mph. Michael Konig then took the footage and compiled it into this eye-popping time-lapse video showing what our planet looks like from up there.

Historic Photo of Mercury Captured by NASA’s MESSENGER Probe

After a seven year journey that involved being slingshotted around the planets in our solar system, NASA’s MESSENGER probe entered Mercury’s orbit on March 17th, 2011. Yesterday the probe beamed back the first photograph ever taken of the planet from orbit (seen above).
