OK, I suspect I might have used a slightly wrong setting on this one. Bunsen's former (custom-built) laboratories in the background, by the way. Where the fact that these newfangled buildings had a gas connection inspired him to design the Bunsen burner.🧪⚛️

Later today, I'll do an introductory lecture on planet motion in the solar system. Here is an animation I prepared for that. It shows, to scale, the orbits and motion of Earth and Mars. The yellow line is the direction in which we here on Earth observe Mars. And as you can see in the video, 1/ 🧪🔭🎢

I just made this video for my astro-for-non-physicist course on the solar system, to illustrate celestial motion. The separate clips are all winners/honorable mentions of the @astro4edu.bsky.social astrophoto contest 2022. So nice to have this material! 🧪🔭🎢
