A little off topic, but this is such an amazing image, I have to put it up here:
This is only a small section of the photograph; see the complete image below.
The full story is on Space.com, where photographer Thierry Legault explained some of the challenges of capturing the image:
“It took just 1/2 a second for Atlantis and the space station to zip across the face of the sun. The solar crossing, called a transit, was only visible from a 3-mile (5-km) wide corridor beneath the flight path of both spaceships, Legault said.”
Here’s the full image; the two spacecraft are those tiny dots in the upper right!
And just for fun, a couple of worldbuilding prompts:
The beings in your world are capable of perceiving this with the naked eye. Why would they have evolved such extraordinary vision, and what else do they use it for?
The vessels in the image are not docking, they are pursuer and pursued, and they are as close to the sun as the telescopic lens makes them appear. What’s going on?
The vessels are actually living creatures and their close encounter with each other and the sun is a mating dance. What kind of creatures are they? Why do they need the sun to mate? How does their mating affect the inhabitants of the world orbiting this sun?
If you get a great story out of these ideas, let us know!
