Experience the latest image taken by the geostationary Himawari 8 satellite every time you open a new tab in Chrome or Firefox. The himawari satellite has been deployed by the Japan Meteorological Agency and takes photographs of Earth every 10 minutes. Since the new tab page is a simple web page, you can also try it online.
đź›° Get the extension from the Chrome web store or the Firefox Add-on gallery.
This extension is inspired by https://glittering.blue/, https://github.com/jakiestfu/himawari.js/ and https://github.com/ungoldman/himawari-urls.
- Switch between visible light and infrared images from Himawari 8, images from the EPIC camera on the DSCOVR satellite, and GOES 16 (can only switch in the extension).
- Loads the latest image, updates automatically.
- Automatically loads images at the optimal resolution (incl retina resolutions). If more than one image is needed, automatically downloads tiles.
- Uses Google's caching to take the load from the image servers
- Caches last version in local storage (compressed jpeg) and immediately displays it when you load the page. Then loads the latest image.
- JSON proxy on AppEngine to get around same origin policy. The code is on the proxy branch.
- Full offline support
- Images are drawn on a canvas so that we can cache and load it easily.
- The Earth always stay centered, thanks to CSS magic.
- Earth is animated when it moves in
