We owe our existence to stars, because they make the atoms of which we are formed. So if you are romantic you can say we are literally starstuff. If you're less romantic you can say we're the nuclear waste from the fuel that makes stars shine.
/ Sir Martin Rees /

Description:

Beautiful golden star also known as Herschel's Garnet Star. With its high luminosity it dominates the field. As it is easily visible also with the bare eyes, it's a very easy target. If T Lyrae is unbeatable in redness, this star is probably the winner in the golden category. This star is actually one of the brightest known stars, a supermassive giant nearing the end of its life. How sad.
