Want to be blown away by the size and beauty of the Milky Way? daveachuk of Vancouver, Canada, created this 8-minute-long flythrough of our galaxy in 3D. It may look like a CGI rendering, but it’s not: it’s actually the result of combining over 400,000 photos captured by the Spitzer Space Telescope across various wavelengths and over 6 years. Gigapixels upon gigapixels of photos were processed and manipulated over 5 months of spare-time work to create what you see above.
Dave has posted a technical explanation of how the 3D effect was done over on Reddit.
