Post your best wallpapers! For on your PC desktop or on a wall!
Contrary to other wallpaper communities on Lemmy, this one does not allow portrait orientation images.

Rules:

  1. Images must be in landscape (horizontal) orientation. Square images are OK too.
  2. Post high resolution images only. At least 1920x1080 for 16:9 images, similar resolution for other aspect ratio's.
  3. No NSFW content (nudity, lewds, etc.).
  4. No AI-generated content.
  5. Credit the creator of the image if you know who it is. You can usually find the source of an image using https://tineye.com/ .
  6. Include the image resolution in the title, like this: [1920x1080].

What is that large dark spot on Jupiter? It's the shadow of Ganymede, Jupiter's largest moon. When Jupiter's moons cross between the Jovian giant and the Sun, they created shadows just like when the Earth's moon crosses between the Earth and the Sun. Also like on Earth, if you were in a dark shadow on Jupiter, you would see a moon completely eclipse the Sun. Unlike on Earth, moon shadows occur most days on Jupiter -- what's more unusual is that a spacecraft was close enough to record one with a high-resolution image. That spacecraft, Juno, was passing so close to Jupiter in late February that nearby clouds and the dark eclipse shadow appear relatively large. Juno has made many discoveries about our Solar System's largest planet, including, recently, rapidly expanding circular auroras.
