|Comment||Thank you for your answer. To check my understanding, I would like to make the following example. Assume at 1 billion light year distance a supernova occur, while it is occurs it moves to 5 billion light year distance. After 1 billion years we will observe the supernova going on and since it moves to a greater distance we will see the supernova occuring with a slower pace. Did I get that right?|
I can answer almost any question about astronomy and related sciences, such as physics and geology. I will not answer questions about astrology and similar pseudo-scientific rubbish.
I have been a professor of astronomy for over 40 years, and am working on an online text/encyclopedia of astronomy, and an online catalog of NGC/IC objects.
Astronomical Journal, Publications of the Astronomical Society of the Pacific (too long ago to be really relevant, but you could search for Courtney Seligman on Google Scholar)
I received a BA in astronomy and physics and a MA in astronomy, both from UCLA. I was working on my doctoral dissertation when I started teaching, and discovered that I preferred teaching to research.
