Here it is: The first clear image of an eclipse of the Sun by the Earth, taken from the surface of the Moon.
This is what last night's lunar eclipse looked like from the Blue Ghost lander's perspective on the Moon. Amazing!

@coreyspowell 🚀 A Moment of Unity for Humanity! 🌍🌕☀️
This stunning image captures something bigger than politics—Earth eclipsing the Sun, seen from the Moon. 🌌
A powerful reminder that we share one planet, one sky, one future. No borders, no sides—just humanity united in awe and discovery.

@GBSMedia @coreyspowell indeed it is.
Apologies for the tone. I am just riled up about the abdication of duty of our elected representatives this morning and our descent into fascism, and you just happened to be in the wrong place at the wrong time.
I hate and detest AI images, if your purpose is to AI up images, its a block.
@kevinrns @GBSMedia @coreyspowell That pic is *really* bad - The "Earth" is actually a picture of the Moon. Who knows what the cratered object in the foreground is supposed to be. (Edited to add, because people get confused when the threads branch out: The pic I'm referring to is not the original one in Corey's post, but the fictional AI painting in the reply.)
I'm with Kevin, let's not pollute the feed with stuff like this when we are admiring *real* pictures, taken from a real place, with a real camera. That's kind of the whole point, here.
@MichaelPorter @GBSMedia @coreyspowell
The whole point is not what it might look like if science fiction was real, but humans are actually taking picture of the Earth, from the Moon, as it actually transits the sun.
We have PHOTOGRAPHS of the backside of the sun, with concerningly large sunspots, rotating to face the earth.
Compared to the best Star Trek, it is deeply meaningful report, proof, poem, epic of human civlization, and not a story. Not a 'suppose' - not 'like this' but THIS.
@MichaelPorter @GBSMedia @coreyspowell
Well Its not a story, dogs didn't do, Vulcans didn't, tardigrades have no cameras. Humans placed a networked camera to snap image hundreds of thousands of kilometres away, through two gravity wells and metric tons of atmosphere. While blasted by deadly radiation.
We have lighthouses too.
Short exposure time.
Just like Apollo 12 in 1969: https://science.nasa.gov/resource/earth-eclipses-the-sun-apollo-12/
@nantucketebooks @coreyspowell I mean, you could if you stepped out and looked at the Moon during the eclipse 😄
Attached, my shitty cellphone pic that I snapped this morning at 3 AM.
j/k, I know what you mean - that would be a really cool shot. I'd like to see a side-by-side comparison of the lunar landscape as it appears normally, and as it appeared during the eclipse.
@coreyspowell
Wow! Great image.
It makes me feel good about the way I imagined it years ago when I published a web page about observing lunar eclipses. Here's how I imagined a lunar eclipse would appear from the moon:
@ryanjyoder Do you mean in the 'north-west' (top left) of the ring of light? I'd assume an irregularity in the Earth's surface - similar to the effect of Baily's beads (https://en.wikipedia.org/wiki/Baily%27s_beads) in the case of when the moon eclipses the sun.
@ryanjyoder @zeborah @coreyspowell
If you consider that the earth is far from round, it's reasonable.
@ryanjyoder @zeborah @coreyspowell
Where are the poles in that picture? It's not like "up" and "down" mean anything.
@ryanjyoder
I suspect that the reason is more mundane:
That ring happens because sunlight is refracted, reflected and diffused through the atmosphere, and some of it reaches the moon even when the sun is geometrically fully obscured by Earth.
The amount of light that makes it through in a given place is likely affected by local
cloud cover, or whether or not a place is over water. That should explain the asymmetric brighter and darker regions.
@deirdrebeth @ryanjyoder @zeborah @coreyspowell Viewed from the surface of the Moon, the Earth is a little more than three times the apparent diameter of the Sun. See the pic below – it is a simulated view from the surface of the Moon about two hours before totality (so the entire disk of the Sun can be seen).
The light at the upper left in the Blue Ghost pic is not a bit of sun peeking through mountains (as you get with Bailey's Beads during a solar eclipse)–the Earth is too smooth (relatively) to produce such a pronounced effect. The ring of light that you see around the Earth is due to refraction of sunlight as it passes through our atmosphere. Red light gets bent the most, *and* the violet end of the spectrum is scattered by the atmosphere, so you get reddish light lighting up the Moon.
What determines the bright and dim regions around the ring is probably mostly atmospheric clarity - places where there are no clouds will be bright, places with some weather will be dim/dark.
@Annaspanner @deirdrebeth @zeborah @coreyspowell
Based on @MichaelPorter excellent answer here, I think we can rule out solar flares (I think...). Since the apparent size of the earth is so much larger compared to the sun, I don't think you could see solar flares.
Why do so many commentators say it is AI generated? Is it taken by the lander, or is it AI? This curious person wants to know.
@Edelruth They're talking about a reply to the original post, not the original post itself. The reply posted its own 'picture' of an 'eclipse' and it was *very* fake looking.
Earth is a Diamond Ring. The key is to take care of it.
@coreyspowell "And the Great Eye is ever watchful."

There is nothing in the image showing the Sun as large as the Earth. You are seeing sunshine refracted through Earth's atmosphere. And the image came directly from Blue Ghost, verified by all the scientists working on the instruments.
If you were right, the Moon would turn completely dark and vanish during a lunar eclipse. In reality, it turns deep red, lit by the ring of fire around the eclipsed Earth -- exactly as you see in the image.
The Earth would cover the Sun completely during an eclipse viewed from the Moon. This is why a lunar eclipse lasts longer than a solar one, where the Moon covers the Sun as viewed from the Earth.
However, this picture can still be real. The sun's disk appears smaller than the disk of the Earth. Refraction of sunlight in the atmosphere would ring the entire Earth in light. This diamond ring effect is due to the Sun being to one side.
Pic is certainly plausible.
@lxo @hydropsyche @coreyspowell
In the modern age, it’s good to be a little skeptical. But I admire that you did it, sought input, and even though it’s impossible to ever give 100% assurance, all of us gave it a think and now we can step back and look at these images and just go…
WOW.
It's from the official Firefly Aerospace Flickr account, which otherwise mostly shows pictures of stuff they send to space. I suppose it's possible they decided to add fake pictures of the eclipse, but that seems like a weird approach for a not particularly self-promotional company to do. Surely if they were in it for the clicks they would be doing this on Instagram, which is full of fakes, not on Flickr, which hardly anyone uses except actual photographers.

Oi
O tamanho aparente de um objeto no céu depende do seu tamanho real e da sua distância do observador.
O Sol tem um diâmetro de cerca de 1,39 milhões de km, e a Lua tem 3.474 km.
A distância média do Sol à Terra é de cerca de 149,6 milhões de km. A Lua está a 384.400 km.
O Sol é cerca de 400 vezes maior em diâmetro do que a Lua. Mas está cerca de 400 vezes + distante da Terra do que a Lua. Isso faz com que ambos pareçam ter o mesmo tamanho no céu.
