There's been a long history of NASA-provided "Blue Marble" images of Earth, but now we're getting a different perspective thanks to photos taken by the Elektro-L No.1 Russian weather satellite. Unlike NASA's images, this satellite produces 121-megapixel images that capture the Earth in one shot instead of a collection of pictures from multiple flybys stitched together. The result is an image that's the highest-resolution image of Earth yet. The image certainly looks different than what we're used to seeing, and that's because the camera aboard the weather satellite combines data from three visible and one infrared wavelengths of light, a method that turns vegetation into the rust color that dominates the shot.
An educator named James Drake obtained over 350 full-resolution photos from the NTs OMZ (Russian Research Center for Earth Operative Monitoring), and used them to make several videos showcasing a day in the life of Earth. The satellite takes a full image of Earth from its stationary point over 35,000 kilometers above the Indian Ocean every 30 minutes, providing the material for the video below. The images have a resolution of one kilometer per pixel, and the one you see above was taken on May 14, 2011. Be sure to check a zoomable version of the image here to see the detail for yourself and be reminded of just how tiny we really are.
Its upside down that's India at the center for reference.

Impressive. ...
"Its upside down ..."
Really? Upside down? Back to school with this one, not ready for prime time. ... Sorry for being so picky.
Great pictures.

(71 posts)are designed to give the illusion that the Americas and Europe are larger than the other continents. That is the point of the northern hemisphere maps. The inverted map you see before you was very popular in the 60's, we had one in my classroom. I loved it and have one on my wall fully laminated 3ft x 6ft (to my wife's displeasure). You can get them in any map store (I actually had to special order mine it had sold out).

(23,309 posts)a world map like this before. 55 years and this is a first. Saved for further study. Thanks.

(40,416 posts)In Australia, with their wonderful sense of humor, you can get a world map with South up and North down. It really expands ones thinking that the North up tradition is nothing but a cultural affectation.
Gotta love Aussies and Kiwis.
Oh! And Go Swans!

(40,416 posts)QED is symmetric through all translations and rotations of space. The only reason why North is up on maps, globes, etc. almost has to be because of cultural bias.
That's why those Aussie maps provide a teachable moment.

No wonder I like Footie* so much. It also explains those incredible leaping marks.

Ahem! As I said, Go Swans!

(111,417 posts)which used the North Star in the northern hemisphere. Maps were oriented so the top was toward that star, which was, after all, "up."
Very early land maps could be oriented in any direction and showed paths and landmarks on a very small scale and showed things like the way to London from Coventry or to Aleppo from Baghdad.

(9,236 posts)if this is just a "single shot" why did they put that effect on it?

Also compare the south pole (at the top) at 15 seconds -vs- 2:55. It's slow, but it is there.

(9,236 posts)guess i'm used to seeing animated radar on wunderground or the like where the clouds zing by... in relation to the size of the continents i guess they are...
thanks again!

(23,356 posts)Can't have that 20th century librul stuff like film. After all, our Founding Fathers fought to maintain our right to use glass plates, and if it was good enough for them.... (an obligatory Michelle Bachmann moment there)
