Reply to comment by Realeron in are there noticeable differences between 1995 first picture and current images of the Pillars of Creation? by Realeron
If you’re looking for movement in deep sky objects, pictures of the Crab Nebula do show it slightly expanding over the decades. This was first noticed by observers in 1921.
The object is an expanding cloud of debris from a supernova that was seen to explode in 1054 AD. A more recent one (SN1987a) has shown dramatic changes over the last 35 years, with more to come.
