The Ring Around Jupiter

It’s not often you see an image of Jupiter’s ring.

This picture (from Astronomy Picture of the Day for 20/7/22) though shows both planet and ring in infra-red light as captured by the James Webb Telescope.

Also prominent is the Great Red Spot as a bright white feature in infra-red and the moon Europa at the centre of a large diffraction spike.

Europa’s Water

This picture (from Astronomy Picture of the Day 14/5/12) shows all the water of Jupiter’s moon Europa as if gathered into a ball and a similar depiction is done for Earth.

Europa's water

If you look at the sizes of the two spheres of water you can see Earth actually has comparatively little. It’s just spread over a large area (the oceans.) Europa has more water in total. A good place to look for extraterrestrial life then, perhaps.
