This is the Surface of a Comet
Back in 2014, the Rosetta spacecraft captured the world’s imagination by arriving at a comet and snapping the first-ever photos of a comet’s surface. Now here’s something that’s even better: a series of photos turned into a motion picture of what it’s like on the comet at ground level.
The 1-second video was made by Twitter user @landru79 using 12.5-second-exposure photos captured on June 1st, 2016, by Rosetta and shared with the world by the Max Planck Institute for Solar System.
“[I]t’s only a pre-work stacking and balancing B/N frames,” @landru79 writes. “Next step color GIF using only filters 22 -orange-, 23 -green-, and 24 -blue-. ~6 RGB possible. Will see… much parallax to manage.”
The dots traveling smoothly toward the bottom of the frame in the background are stars, while the fast-moving streaks of light in the foreground are dust particles.
