Can anyone ELI5 to me please what it means when photographers 'merge' the photos? How do they all line up? How separately are these photos taken?

You can line them up when the object stays the same whilst photographing, which is the case with most space objects. When you then get many almost identical photo's you can use software to stack those photo's on top of each other.

There's another thing you need to know; the more light reaches the sensor of your camera, the more data you have, the more detail you can get in the end result. So when you take many photo's you have a lot of data and thus a lot of detail as well, when everything goes right that is.

Okay I get that part, but are you saying that the photographer is calibrating the camera every night? The editing makes the most sense to me... I guess I'm hoping for someone TO ELI5 or to literally walk me through what the photographer physically does to get this...

Sounds like a good video on the topic will help you out more than a comment about it. It will visualise the process.
