A bit cheeky, as I submitted my own processing of this image to APOD a couple of weeks ago, but they decided to post someone elses' work. No problemo. :)
Gonna attach a couple of images from my own processing.

I like your one better, but still the moonscape feels poor-coloured

The albedo of the Moon is about 0,12 and I feel that the surface of the Moon should be much darker in the image.

albedo of the Earth is 0.1 to 0.4, so it's ok as long as we are buying the white clouds as over-saturated

Great observation, that us newbies may not think about. IF you are actually on the near side of the moon, you would never see an Earthrise! Unless something went VERY wrong!

That's not the case. The moon's obliquity and orbit eccentricity lead to the moon tracing out an oval shape about 13.5° by 5.5°. For observers located on the near side, Earthrise can be seen at all latitudes within longitude ranges of E83°≤ L ≤ E90°, and W83°≤ L ≤ W90°. The longitude window opens up as the poles are approached. The oval's orientation is not fixed. It appears to precess probably due to the Metonic cycle (18.6-yr orbital precession period). This oval is analogous to the analemma traced in our sky by the sun but, unlike the sun's figure-8, the oval's orientation is not stable at a fixed observer location. So most of the moon's near-side does not see Earthrise, but near the limb, it is visible.

This was taken from a vehicle orbiting the Moon. If one could be fixed in space there, or more practically, be in a base on the Moon directly below, the Earth would be always there forever, but it would bob up and down each month because of the eccentricity of the Moon's orbit as it circles Earth. It should be easy to created a MOVIE showing that happening, from the present wonderful image.

Staring into that inky black is exhilarating, awe inspiring and frightening all at the same time. You look at it and it looks at you (Nietzsche was right).

Ann, is that “marble” from the moon?

I wish people would quit complaining about it being a repeat. There ate great shots that deserve to be seen again or for the first time if they were missed earlier. [b][i][color=#0000FF]Hell we have photos here that are millions or even billions of year old![/color][/i][/b]

Well, the things the photos are taken [i][u][b]of[/b][/u][/i] may be millions or billions of years old, but the photos themselves are not! And not even the photons hitting the detector (or your retina) are more than a few microseconds old. At least if the detector is in the Earth's atmosphere. If the detector is in space, I think the photons could be pretty old indeed. But only if there's a direct hit on the detector, unaltered by a lens or mirror. [ This subject came up before, and I believe I'm remembering it correctly, but I'm sure someone will correct me if I'm not :) ]

And I guess, since photons don't age, the distinction may be irrelevant.

Just hoping someone will confirm why there are no stars in the background, after all, it is the night sky.

Because if you expose a shot for the Earth in full sunlight, stars are not bright enough to see. Go outside with an adjustable camera at noon and shoot the landscape. Go back out at night and shoot the same scene, with the same settings. No stars.

BTW, the same is true for the Moon. Take a properly exposed image of the Moon at night and you will not normally see stars around it.

It's Sunday. Sunday are repeat days, where old APODs are featured again, so that the editors get a day off.

Ann

Thank you for explaining this, Ann. Peace to you and all our Family on our beautiful Home planet.

Yes, this is confusing! Could've at least changed the caption as it's now 54 years ago!
[/quote]

Yes. An email alerted me to this same oversight. My bad. It has now been fixed on the main NASA APOD. I apologize for the error.

Well, I was just thinking - maybe we could play marbles with the Earth on the surface on the Moon, wouldn't that be fun - but maybe not...

Ann

Ah! Beautiful Earth rise; an oldie but a goodie! 8-)

The original photo was taken with the horizon running vertically. We mere humans would have trouble with that.

This very post appeared on APOD on December 24, 2018. Confused by this repost with the same wording.

I am delighted folks can digitally recompose images like this, but honestly, I like the original published one much better. It has Earth really floating in the inky black of space, not appearing to be sitting on the moon's surface. The space between Earth and Moon in the (second image) shows Earth's phase, and really gives it a sense of distance, which this one does not.

How?
Apollo 8 (December 21–27, 1968) was prior to today, 2/27/22.
Please?

It's an old photo. Jim Weigang has just processed it all over again, to make it look even more brilliant than it did before.

Take a look at this short film clip from 1901. In the caption, it says:

[quote]54 years before Marilyn, there was Florence Georgie! Here's the 1901 film inspiration for Marilyn Monroe's white dress moment in the 1955 movie The Seven Year Itch. [b][color=#FF0000]Enhanced using AI neural networks[/color][/b], to 4k 60 fps.[/quote]

So someone has made this old film clip look better. In the same way, the Earthrise photo from 1968 has been remastered to look even better.

Yeah, that's an amazing image.

Hey guys, wanna play marbles?

[b] Explanation: [/b] "Oh my God! Look at that picture over there! Here's the Earth coming up. Wow is that pretty!" Soon after [url=https://history.nasa.gov/afj/ap08fj/16day4_orbit4.html]that pronouncement[/url], 50 years ago today, [url=https://time.com/5479821/earthrise-picture-history-apollo-8/]one of the most famous images ever taken[/url] was snapped from the orbit of [url=https://solarsystem.nasa.gov/moons/earths-moon/overview/]the Moon[/url]. Now known as "[url=https://en.wikipedia.org/wiki/Earthrise]Earthrise[/url]", the iconic image shows the Earth rising above the limb of the Moon, as [url=https://www.smithsonianmag.com/science-nature/who-took-legendary-earthrise-photo-apollo-8-180967505/]taken by the crew[/url] of [url=https://www.nasa.gov/mission_pages/apollo/missions/apollo8.html]Apollo 8[/url]. But the well-known [url=https://apod.nasa.gov/apod/ap150906.html]Earthrise[/url] image was actually the [url=https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=4593][i] second [/i] image[/url] taken of the [url=https://apod.nasa.gov/apod/ap181223.html]Earth rising[/url] above the lunar limb -- it was just the first in color. With modern digital technology, however, the real first Earthrise image -- originally in black and white -- has [url=https://jw9c.blogspot.com/2018/01/earthrise-1.html]now been remastered[/url] to have the combined resolution and color of the [url=https://archive.org/details/as08-13-2329]first[/url] [url=https://archive.org/details/as08-14-2383]three[/url] [url=https://archive.org/details/as08-14-2384]images[/url]. Behold! The [url=https://photos.app.goo.gl/OinnT83WZE7TSW3K2]featured image[/url] is a close-up of the picture that Apollo 8 astronaut [url=https://www.universetoday.com/13804/apollo-8-astronaut-bill-anders-reflects-on-earthrise-picture/]Bill Anders[/url] was [url=https://historycollection.jsc.nasa.gov/JSCHistoryPortal/history/oral_histories/AndersWA/AndersWA_10-8-97.htm]talking about[/url].
