Solar Textures
https://www.solarsystemscope.com/textures/
These textures represent real planetary maps in equirectangular projection. You can use them in 3D rendering, or just open them in any image viewer and explore the surface of planets :)

Borman: All right, we're gonna roll. Ready… Set…
Anders: The impact crater with uh - at uh - just prior to the subsolar point on the south side, in the floor of it, uh, [unintelligible], there is one dark hole. But I couldn't get a quick enough look at it to see if it might be anything volcanic.
Anders: Oh my God, look at that picture over there! There's the Earth comin' up. Wow, is that pretty!
Borman: Hey don't take that, it's not scheduled.

Anders: You got a color film, Jim? Hand me a roll of color, quick, would you?
Lovell: Oh man, that's great.
Anders: Hurry.
Lovell: Where is it?
Anders: Quick
Lovell: Down here?
Anders: Just grab me a color. A color exterior. Hurry up. Got one?
Lovell: Yeah, I'm looking' for one. C 368.
Anders: Anything. Quick.
Lovell: Here.
Anders: Well, I think we missed it.
Lovell: Hey, I got it right here [in the hatch window].
Anders: Let me get it out this one, it's a lot clearer.
Lovell: Bill, I got it framed, it's very clear right here!

Lovell: Got it?
Anders: Yep.
Lovell: Take several, take several of 'em! Here, give it to me!
Anders: Wait a minute, just let me get the right setting here now, just calm down.
Lovell: Take -
Anders: Calm down, Lovell!
Lovell: Well, I got it right - aw, that's a beautiful shot…Two-fifty at f/11.

Anders: Okay.
Lovell: Now vary-vary the exposure a little bit.
Anders: I did, I took two of 'em here.
Lovell: You sure you got it now?
Anders: Yeah, we'll get - well, it'll come up again, I think.

A Catalogue of Eclipse Cycles Solar- and Lunar-Eclipse Predictions from Antiquity to the Present
https://www.eclipsewise.com/eclipse.html
Welcome to EclipseWise.com - a website dedicated to predictions and information on eclipses of the Sun and Moon. Although I've been responsible for the NASA Eclipse Website for many years, this new website based on the recent publications Thousand Year Canon of Solar Eclipses 1501 to 2500 and the Thousand Year Canon of Lunar Eclipses 1501 to 2500.
EclipseWise.com features a graphical interface offering a more intuitive way of accessing eclipse predictions. For example, the figures below present a concise preview of all upcoming solar and lunar eclipses over the next seven years. Each of the small eclipse figures links to a page about that particular eclipse. Visit the Key to Solar Eclipse Figures and the Key to Lunar Eclipse Figures for a detailed explanation of these figures.
If you are interested in eclipses of the Sun, go directly to the Solar Eclipses main page. Similarly, you can find details about eclipses of the Moon on the Lunar Eclipses main page. Each of these pages offers thumbnail previews of upcoming eclipses that link to pages with more information for each eclipse. You'll also find many more links at the bottom of these two key pages.
At the top and bottom of every page on EclipseWise, you'll find handy links for:
