-There is hydrogen in Enceladus's plumes which implies there are hydrothermal vent(s) on its sea floor. This has gotten scientists excited because of the ecosystems around hydrothermal vents on Earth.

 

-Hubble has observed multiple plumes in the same location on Europa, which would be an ideal location to sample water without a crazy drilling operation. There are also 'hotspots' on the surface of Europa which coincide with plume locations.

 

-NASA people still suck at speaking to the public (and I need to take more time writing a post like this so I don't have to edit it multiple times).

You might notice that the pictures are black-and-white, small, and noisy. There are good reasons for all of those things -- actually one good reason: As Cassini passed within 2000 kilometers of Saturn's cloud tops, it was traveling at a speed relative to Saturn of 34 kilometers per second. That is very, very fast, almost too fast for the camera to take images without motion blur. To avoid blur, you have to take very short exposures, which means the images look noisy. You have to maximize the number of photons reaching your camera, which means not placing any color filters in front of the camera, so the pictures are grayscale. Even with that, there would be some blur and limitations to how fast the spacecraft can get so many images off of its detector, so they downsampled the images to half the camera's native resolution in order to get a somewhat continuous strip of photos of Saturn's atmosphere throughout the plunge.

A Whole New Jupiter: First Science Results from NASA’s Juno Mission

Juno Media Teleconference

Quote

As NASA's Juno spacecraft flew through the narrow gap between Jupiter's radiation belts and the planet during its first science flyby, Perijove 1, on August 27, 2016, the Stellar Reference Unit (SRU-1) star camera collected the first image of Jupiter's ring taken from the inside looking out. The bright bands in the center of the image are the main ring of Jupiter's ring system.
