As the APOD explanation reminds us, if our sun were in a cluster of stars our night sky would be bright. God's design places this planet we call earth in the outer region of the Milky Way Galaxy where we have a view of many stars but also have a night sky which is dark enough for most to sleep and keep many star gazers entertained and informed.

APOD Background
"Explanation: If our Sun were part of this star cluster, the night sky would glow like a jewel box of bright stars. This cluster, known as M53 and cataloged as NGC 5024, is one of about 250 globular clusters that survive in our Galaxy. Most of the stars in M53 are older and redder than our Sun, but some enigmatic stars appear to be bluer and younger. These young stars might contradict the hypothesis that all the stars in M53 formed at nearly the same time. These unusual stars are known as blue stragglers and are unusually common in M53. After much debate, blue stragglers are now thought to be stars rejuvenated by fresh matter falling in from a binary star companion. By analyzing pictures of globular clusters like the featured image taken by the Hubble Space Telescope, astronomers use the abundance of stars like blue stragglers to help determine the age of the globular cluster and hence a limit on the age of the universe. M53, visible with a binoculars towards the constellation of Bernice's Hair (Coma Berenices), contains over 250,000 stars and is one of the furthest globulars from the center of our Galaxy.'

Electrelane - Blue Straggler
Brighton, England's Electrelane formed in 1998, eventually comprising guitarist Mia Clarke, bassist Rachel Dalley, drummer Emma Gaze, and keyboardist/guitarist Verity Susman. Sharing an equal amount of fondness for Krautrock, vintage equipment like the Farfisa organ, and modern production techniques, the band made their recorded debut in January 2000 with the Film Music single on In Denial.
