Astronomical time lapses are fascinating and there should be more.

you are free to create your own as NASA observatories release their imagery free to the public as they were paid for with the public's money from taxes. the problem with creating timelapse videos would be if the platform viewed the same object at least annually to see the changes.

I have often thought about looking through archives but has not been easy for me (don' know how to) search though years of data for multiple views (years apart) of the same objects.

I have been wondering about binary star systems. I think some of them are human scale orbital periods.

Part of the reason you don't see them more is because commercial satellite mega-constellations (like Starlink) work against long exposure times by literally clouding and brightening our view of space. (1)

Not really sure how this has anything to do with space based platforms like Chandra (which is x-ray) and Hubble which is well above Starlink. Also, Starlink is only a couple of years old to be problematic, but the ground based observatories have had clean skies for decades before.

This just really feels like someone trying to interject a pet peeve. Whether the peeve is valid or not, it's not the problem here.

Astronomical objects that visibly change in human timescales are pretty rare. A naked-eye visible supernova remnant was one of the first clues that challenged the idea that the heavens were static, permanently set by God.

One of my favorite examples of astronomical timelapse is the motion of objects around SagA*. That I think might be the first example I saw. I'm not sure if they set out to make multiple observations specifically to map this motion or if it was something saw they could do from existing data. S
