Starship Asterisk*

This moon now always reminds me of the [url=https://astrodonimaging.com/gallery/wr-16-bubble-nebula/]WR 16 nebula[/url].

Is it just the scattered lighting or is the Saturn's side of Mimas a low land with a steep borderline ?

Looks like an optical illusion to me. The upper edge of Mimas shows no sign of any ridge around the moon that I can see, unlike, say, Iapetus:

Yup, as far as I know, Mimas has no global ridge like Iapetus, at least like the unique walnut-shell ridge in the image.

APOD repeats 17% of the images and comments

By design, Sunday APODs are repeats (14%). Repeats on other days are unusual. I guess that happens when something unexpected pops up that takes the editors' time.

This image is a repeat yes?

I take it is lit by reflected light off of Saturn! Second hand light! :mrgreen:

Yes. The description says "An enhanced version better reveals the ... moon lit by sunlight reflected from Saturn itself." (I deconvoluted the sentence structure.)

cursor doesn't work. just a mini view o display, doesn't rotate.

The moon won't rotate when you click and drag your cursor. It's not supposed to. Sliding your cursor over the image will show the enhanced Saturn-lit view (in a well behaved browser); without the cursor over the image you see the unenhanced view.

Little moon with the big Herschel crater! :shock:

Yes I believe so. The title Mimas in Saturnlight is probably meant the same as seeing by Moonlight, even though the Moon doesn't produce its own light. It is reflected light from the Sun. This is opposed to the meaning of producing its own light as in streetlights, lamp light, flashlight, and candle light. Oh, and sunlight.

That is one giant golfball!

[b] Explanation: [/b] Peering from the shadows, the Saturn-facing hemisphere of Mimas lies in near darkness alongside a [url=http://photojournal.jpl.nasa.gov/catalog/PIA17213] dramatic sunlit crescent[/url]. The mosaic was captured near the Cassini [url=https://saturn.jpl.nasa.gov/resources/7580/]spacecraft's final[/url] close approach on January 30, 2017. Cassini's camera was pointed in a nearly sunward direction only 45,000 kilometers from Mimas. The result is one of the highest resolution views of the icy, crater-pocked, [url=https://www.jpl.nasa.gov/news/news.php?feature=4342]400 kilometer diameter moon[/url]. An enhanced version better reveals the Saturn-facing hemisphere of the synchronously rotating moon lit by sunlight reflected from Saturn itself. To see it, slide your cursor over the image (or [url=https://apod.nasa.gov/apod/image/1908/MimasPIA17213_1024.jpg]follow this link[/url]). Other Cassini images of Mimas include the small moon's large and ominous [url=https://apod.nasa.gov/apod/ap210531.html]Herschel Crater[/url].
