A nearly 20-foot-in-diameter globe unveiled in Japan displays Earth's current appearance in more than 10 million pixels using constantly updated satellite images.
A new, gigantic Japanese globe unveiled in Tokyo features 10,362 OLED panels that show constantly updated satellite images of Earth.
The nearly 20-foot-in-diameter globe, called Geo-Cosmos, displays Earth's current appearance in more than 10 million pixels, an incredibly high resolution that is ten times sharper than the previous model, built with LED panels.
The interactive exhibit at the National Museum of Emerging Science and Innovation also features interactive touchscreens that allow visitors to browse earth science images and data from all over the world. For instance, the touchscreens feature simulations of the March 11th earthquake that triggered the massive tsunami in northeast Japan.
Watch museum-goers marveling at the globe and playing with the interactive displays:

A good portion of the earth is constantly in the dark. According to this "real-life" image apparently nobody ever sleeps!
This is an interesting way to see weather patterns across the whole planet without the distortion of flattening the images. I liked seeing the tsunami ripple spread from Japan and go across the Pacific.
Hi Dzmitry, You're right. When I was researching this, the information I found said "near real-time" and I assumed that's how they accounted for the fact that half the earth is in the dark at any given time, but I neglected to mention that in my post. Thanks for pointing that out. Laura
because it's not a continuous display, but a collection of 10,362 about 4" x 4" OLED panels. As you can see in the video, they are all placed at different angles with some places having more "dead space" than others. So, to make it easier, they simply took the amount of pixels in one of those panels and multiplied it by the number of screens.
It's a great learning tool to inspire young minds. There are many worse ways that people spend their money.
I guess that's why they need all those computers to merge pieces of data in a manner that's presentable. Thank you for your quick reply!
Hi Dzmitry, I looked into this more, because I was interested in finding out exactly how often they update it. The museum website says, "It is possible to see an image of the Earth as early as the morning of that current day." And another Tokyo publication, which previously reported that the globe was "constantly updated," revised its post to say the globe features images "updated daily." Clearly not as exciting as we thought, but still very recent images. Thanks for asking about this because this is an important point to clear up. Laura
