About this image

This Hubble Space Telescope image shows a dense collection of stars crammed together in the Milky Way galaxy's ancient central hub. The region surveyed represents one entire field of the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS) program. The region is 26,000 light-years away.

Studying the stars in this field, astronomers identified for the first time 70 white dwarfs, the fading embers of sun-like stars. These ancient, dead stars hold information on the galaxy's infancy.

Hubble's Advanced Camera for Surveys made the observations in 2004 and 2011-2013.
