Summary
| Description |
English: A team of astronomers analyzed observations by NASA's Hubble Space Telescope taken over a span of 18 years to measure the dynamic motions of stars within the Draco dwarf galaxy. The telescope's extensive baseline and data archive enabled the team to build the most accurate three-dimensional map of the stars' movements within the system. These improved measurements are helping to shed "light" on the mysterious qualities and behavior of dark matter, the universe's invisible "glue."
