This image from NASA's Hubble Space Telescope reveals an ancient, glimmering ball of stars called NGC 1466. It is a globular cluster — a gathering of stars all held together by gravity — that is slowly moving through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbors.
Blue straggler stars are blue, bright stars, with a higher mass than the average for a cluster, and they are expected to sink towards the center of a star cluster over time. Those closest to the cluster core are the first to migrate inwards, with more distant blue stragglers progressively moving inwards over time.

| About The Data | |
| Data Description | The HST observations include those from program (A. Sarajedini). |
| Instrument | HST>WFC3/UVIS; HST>ACS/WFC |
| Exposure Dates | February and July 2016 |
| Filters | WFC3/UVIS: F336W and ACS/WFC: F606W, and F814W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3/UVIS and the ACS/WFC instruments on the Hubble Space Telescope. Several filters were used to sample narrow and wide wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F336W Green = F606W Red = F814W |
