Astronomy Picture of the Day - In Ganymede's Shadow
APOD.NASA.gov ^ | 7 Oct, 2022 | Image Credit & Copyright: Andrew McCarthy

Explanation: At opposition, opposite the Sun in Earth's sky, late last month Jupiter is also approaching perihelion, the closest point to the Sun in its elliptical orbit, early next year. That makes Jupiter exceptionally close to our fair planet, currently resulting in excellent views of the Solar System's ruling gas giant. On September 27, this sharp image of Jupiter was recorded with a small telescope from a backyard in Florence, Arizona. The stacked video frames reveal the massive world bounded by planet girdling winds. Dark belts and light zones span the gas giant, along with rotating oval storms and its signature Great Red Spot. Galilean moon Ganymede is below and right in the frame. The Solar System's largest moon and its shadow are in transit across the southern Jovian cloud tops.

“In Ganymede’s Shadow”

That would make a great title for a thriller.

I hate when you have a spontanious spot failure of gravity and it leaves a pock mark like that.

You can see this from your back yard with a moderately decent telescope. Great images here! Thanks for posting.

Oldest daughter brought her telescope over Labor day. Jupiter and 4 moons were visible. Pretty cool.

The real history of Ganymede could easily be more thrilling than anything anybody could make up

The largest planet and the largest moon in one image. In Greek mythology, Ganymede was the gay lover of Zeus, known by the Romans as Jupiter. Those ancient Greeks were perverts.

Truly amazing how every other edge is softened but the shadow of the moon against Jupiters Gas atmosphere is laser clean. Fascinating... /s...

I know, right? I live near there in the desert SW of Phoenix in Maricopa, and we have the Dark Skies program in our city. I imagine Florence has it too, which makes star gazing easier. We gave our telescope to our 12 yo grandson a few years ago and he uses it a lot more than we ever did. Iโ€™ll let him know about this so he can see whatโ€™s possible from his backyard.

It's likely because you're looking at Jupiter's cloud bands/storms which are naturally soft looking in appearance.

this is another fkn fake picture man... htf can you actually sit there and defend it. you must be as duped as the rest oooohing and aaaahhing over it... there aint no fkn way an amateurs telescope caught that much clarity of the moon, and no way would the shadow be that crisp on a gas.

I shot this from my backyard about a week ago...Not really setup for planetary and was using a consumer grade DSLR camera to shoot the video which was then processed. Tell your grandson much better planetary images can be had with an inexpensive web cam connected to the telescope. They'll deliver more frames per second etc. I tell people if they're interested to focus on the close big bright things first...Planets, Lunar, star clusters, then if they still want to pursue it, graduate later up to deep space stuff, galaxies, nebula etc...

Reminds me of this:

Farmer In The Sky is a 1950 science fiction novel by American writer Robert A. Heinlein about a teenaged boy who emigrates with his family to Jupiter’s moon Ganymede, which is in the process of being terraformed.

Farmer in the Sky was the first scifi novel I ever read(back in ‘56).

Hooked me good!

Actually he's not the first amateur to actually get surface detail from Jovian moon. Btw, you seem really angry.

I think this is bullsh*t!! and I am angry. APOD is primarily for children and their education. this site continuously posts pretend pictures of everything from this to Nebulas photoshopped into our Milky way and passing it off with their “explanation” as being real!! It’s just like fake news!! these kids and it seem like a lot of adults dont know that half these pics are fake!!

I seen your pic of Saturn! It’s awesome!!! You know why!!?? because its real!! its not photoshopped, it’s not enhanced!! It’s real!! Nebulas millions of light years away, belong there on their own. not photoshopped behind an Idaho Mountain Nightscape and saying some BS in an explanation that this was some amateurs 117 different photos etc etc.

I’ am angry! this one isnt as bad, but its still promoting lies. There is NO WAY and amateur’s telescope picked up that much definition on that moon especially being in front of that much reflected light from Jupiter’s surface gas.
