Quote: "Space, let me repeat is enonnous. T he average distance between stars
out there is 20 million million miles."
--> This quote stood out to me because I never really knew how far away the stars really were. Whenever I'm out at night, and stars are out, they always seem to be so close....but in reality, they're not. The quote just goeos to show that space truly is another large world, that's full of interesting things and information.
Question: How do researchers began to estimate how many stars are in the milky way? What specific tools and methods do they use to calculate and come up with such a large number?
--> For example, in the packet it said that estimates range from 100 billion or so to perhaps 400 billion. And even though this may be true, I know there are ways that they came up with that number, and I'm unclear how.
Comment: Overall, I enjoyed reading the packet. Similar to what I said in my response about the first chapter, I never really thought about the stars in the sky, and the world that exists beyond the clouds, besides heaven. I think that it's amazing how much time and effort astronomers and researchers spend to learn, observe, experience, and discover new thing. But hey, id someone is passionate about something, they will put the time and effort in to support and learn more about their passion.
