This image from the NASA/ESA Hubble Space Telescope shows a globular cluster called Messier 2. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet and optical parts of the spectrum. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / G. Piotto et al.

From a great distance, our Milky Way Galaxy would look like a thin disk of stars that orbits once every few hundred million years around its central region, where hundreds of billions of stars provide the gravitational ‘glue’ to hold it all together. But this pull of gravity is much weaker in the Galaxy’s far outer disk. There, the hydrogen atoms making up most of the Milky Way’s gas disk are no longer confined to a thin plane, instead they give the disk an S-like, or warped, appearance. Image credit: Xiaodian Chen.
