Do Distant Celestial Objects Still Exist as We See Them?

In summary, distant celestial objects, such as stars and galaxies, do still exist as we see them, but the light we receive from them may have taken thousands or even millions of years to reach us. This means that we are seeing these objects as they were in the past, not as they are currently. However, due to the vast distances involved in space, it is difficult to know for sure if these objects still exist in their original form. Some may have changed or even disappeared entirely by the time their light reaches us.

The light by which we see distant deep space objects left those objects thousands, millions, even billions of years ago, yet we speak of them in the present tense, Perhaps this is just a convenience; they may be more accurately referred to in the past tense. In any event, given that the light forming the images we see actually left the objects so long ago, how do we know those objects still exist?

Welcome to PF!
I suggest you to post your question under Astronomy section of the forum, in this thread you are supposed to introduce yourself.

Short answer to your question, it depends on the object you are referring.
