The following file is not exactly the file we use to render Skybeautiful. This file represents the largest extraction we were able to get correlating the Hipparcos original dataset against the Hipparcos New Reduction. We include only stars that have a Henry Draper Collection (HDEC) number assigned to them. HDEC is the most common catalog reference number and allows us the best cross-service lookup results. In other words, most star databases out there include an HDEC number with their stars. Many of these stars have a magnitude greater than 9 and our tests show we can't render anything that dim and maintain a good presentation for the stars humans can actually see, so we don't include them in SkyBeautiful.

Well...No. Space-time discussions aside, the following video and file download represent an X,Y,Z positioning of stars from the Hipparcos New Reduction data. Using simple geometry we converted the parallax of each star in the catalog into a distance measurement. The resulting file was converted into a Stanford PLY file, which will open in most 3D software programs with plugins or conversion.
This is a point cloud model. It is a collection of vertices (points) that is best viewed in applications like MeshLab. As we say here, use this data at your own risk!

While anaglyphic imagery is becoming more and more popular, it's still pretty hard to find the glasses. You can buy them or you can make your own. Here are some links.

OK, this isn't really a download, but we had to find a place to put this site. It's extremely addictive, and of course your first taste is free!
