Amazing Hubble, I can't wait for the Webb telescope.
#HubbleClassic Today, Hubble has been in space for a full Saturn year, which is equal to 10,759 Earth days (or about 29.5 Earth years). These images, taken from 1990 to 2019, show how Hubble's views of #Saturn have gotten better over time as its cameras have improved.pic.twitter.com/j2oYmZXlaa

@illucifer why was the first picture of Saturn so blue? Is it to do with the imagining equipment back then? Or how we recoloured the images which has changed in light of new data? Or was she not feeling the blue look? -
I’m clueless about this I’m afraid!
@DrCarpineti will definitely know more than me!pic.twitter.com/pgHLBhfFfH - Näytä vastaukset

Other than the one space walk how does the camera improve?
-
There have been many spacewalks to upgrade Hubble over time. https://www.nasa.gov/content/goddard/hubble-history-timeline … Tidbit: the "broken" mirror is still there, the new cameras just correct it with tiny lenses!

Why does the angle of Saturn change from picture to picture?
-
Because it doesn't orbit in the same plane as us so sometimes we view it from slightly above and sometimes from slightly below.
