What does Hubble show of Jupiter? I realize that HST is primarily used as a deep-sky instrument, but it has produced iconic planetary images, and it doesn't have atmospheric effects.

As an instrument, HST is wonderful and could deliver a perfect answer to this, at least over the set of observations, which are more sparing than amateurs'. (HST may image Jupiter only about once a year, while amateurs image it every day apart from solar conjunction.) However, the public releases are not carefully controlled by any single set of creative choices and many public releases of HST images of the planets are obviously candy-colored reflecting varying aesthetic decisions by the image processing individuals and not real changes in the planets.
If someone would like to take raw HST images (which are publicly available) from two separate dates and process them in comparable fashion, that would give us a clean result. |
