Astronomy Quote by Seth Shostak
“The central region of the Milky Way, known as the bulge, is stuffed with literally tens of billions of stars. And most of these are old - considerably older than our Sun or its neighbors - because this part of the galaxy formed first. Consequently, bulge stars are generally deficient in heavy elements.”

![“The photograph is in my hand. It is the photograph of a man and a woman. They are at an amusement park, in 1959. [...] I'm tired of looking at the photograph now. I open my fingers. It falls to the sand at my feet. I am going to look at the stars. They are so far away, and their light takes so…” quote by Alan Moore](https://sms4smile.com/quotes/img-quotes/8ab/alan-moore-583_astronomy_the-photograph-is-in-my-hand-it-is-the-p_2425984.jpg)
