Re: APOD: Ganymede from Juno (2023 Nov 28)
The featured image was captured in 2021 by NASA's robotic Juno spacecraft when it passed by the immense moon. The close pass reduced Juno's orbital period around Jupiter from 53 days to 43 days. Have I understood this correctly? That Juno's close pass has affected Ganymede's orbit by 10 days?! Sure...

Yes, I know that the Saturn picture has been color-enhanced to bring out details in Saturn's atmosphere. I'll never forget my shock at first seeing it, because the concept of false or mapped color was unknown to me. I disliked Saturn for a while after seeing that image. Oh well, that's me... :roll:...

Re: APOD: Kemble’s Cascade of Stars (2023 Jan 03)
According to Google:
whereasA constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline
So... basically an asterism is a pattern that isn't a pattern ...???An asterism [is] a pattern of stars that is not a constellation.

Re: APOD: Venus and the Triply Ultraviolet Sun (2022 Mar 06)
I'm very doubtful you were seeing any edge blur due to the atmosphere. Well.. from my admittedly limited understanding, the thick atmosphere will still distort the image we see from here - you're not seeing the atmosphere per se, but light passing through it will be refracted nonetheless. This, alo...

Hold Infinity in the palm of your hand
And Eternity in an hour."
