Artist’s Impression: Stellar streams in and around the Milky Way

This artist’s impression shows a myriad of stellar streams in and around the Milky Way. These stretched-out remnants of dwarf galaxies and star clusters showcase gravitational interactions between stars, clumps of dark matter, and the entire galaxy. Rubin Observatory will reveal many more stellar streams than we have seen thus far, enabling scientists to study our galaxy’s history and properties of dark matter in more detail than ever before.

Alt text: An artist’s impression of streams of stars around a galaxy. The galaxy occupies most of the image as a fuzzy blue-white oval with spiral features extending out clockwise. The light clouds are interspersed with small dark brown splotches in the same spiral pattern around the center, representing dust clouds. The galaxy’s center is a bright yellow glow. Overlaid on top of and surrounding the galaxy are several criss-crossing, faint tendrils of stars that represent satellite dwarf galaxies and star clusters that have been stretched out into long thin lines. The tendrils have various lengths and widths, though all are arcs rather than complete circles. The background is black.
