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.
