Mysterious Force Punched Gigantic Holes in the Milky Way – Could It Be Dark Matter?

Scientists have discovered mysterious gaps in the Milky Way’s stellar stream GD-1, likely caused by a massive, unseen object at least a million times the mass of the Sun. While no visible black hole or galaxy has been found in the area, researchers suggest it could be a dense "bull

Our universe is held together with an invisible "glue" – what we call dark matter.
Most galaxies are made up of mostly dark matter. Astronomers can gain insight into what this substance is, and how it impacts a galaxy's evolution, by understanding how dark matter is distributed within a galaxy.
Enter Hubble. With its long-running mission, scientists have the unique ability to examine data that spans 18 years to measure the motion of stars in the Draco dwarf galaxy, located about 250,000 light-years away. Portions of the galaxy are seen in these two Hubble views.
Using Hubble data, a team of astronomers built the most accurate three-dimensional map of the stars' movements. These measurements will help shed light on the mysterious qualities and behavior of dark matter.
