Reply to comment by EnumeratedArray in James Webb Telescope captures the same galaxy at three different points in time in a single mind-boggling image by mirzavadoodulbaig

The galaxy drove to work, but took 3 different routes. One route had extra gravitational stop lights which caused it to arrive 320 days late. And another one 1000 days late. The fastest route was relatively direct though. We get to see all three in one picture.

The light from the galaxy, not the galaxy itself.

That’s the same thing when it comes to an image and how we are collecting the data

It's not the same thing as the galaxy itself moving, though. And it's much easier to understand how light can take different paths than a galaxy taking different paths. I wanted to make extra clear what was doing the traveling in the analogy.
