Globular cluster M4, NOAO
This sparkling picture taken by the NASA/ESA Hubble Space Telescope shows globular cluster M4. M4 is relatively close to us, lying 7200 light-years distant, making it a prime object for study. It contains several tens of thousand stars and is noteworthy in being home to many white dwarfs — the cores of ancient, dying stars whose outer layers have drifted away into space.
