    Not to self-plug, but here's my video of the same four planets:

    <a href="https:&#x2F;&#x2F;sefffal.github.io&#x2F;images&#x2F;orbital-animation.mp4" rel="nofollow">https:&#x2F;&#x2F;sefffal.github.io&#x2F;images&#x2F;orbital-animation.mp4

    The creator of the GIF above used a data from a range of different telescopes and wavelengths, whereas I made this with using data only from same telescope (Keck), instrument, and wavelength (3.5 microns; near infrared).

      I’m curious what that blight red smoke flickering around the star is. Some kind of interplanatory gas?

        I think it might just be diffraction artifacts animated by the interpolation (I hereby invoke cunnignhams law)

          That’s right. We only have images take every year or so, so I did a motion interpolation between the images using Keplers laws. Diffraction close in gets pulled around by the interpolation.

      omg both animations are gorgeous; those far out orbits sure take a long time to complete

      How come both videos only go up to 2022 or so? Did we stop watching this star? Or is there just a delay on releasing the data?

        I think there’s a couple new images. I’ll upload an updated one some time.
