Hubble uncovers largest known population of star clustersThis new image from Hubble of the massive galaxy cluster Abell 1689 shows the phenomenon of gravitational lensing with unprecedented clarity. This cluster acts like a cosmic lens, magnifying the light from objects lying behind it and making it possible for astronomers to explore incredibly distant regions of space.
As well as being packed with galaxies, Abell 1689 has been found to host a huge population of globular clusters. While our galaxy, the Milky Way, is only home to around 150 of these old clumps of stars, Hubble astronomers estimate that this galaxy cluster could possibly contain over 160,000 globulars overall – an unprecedented number.
