Want to see our DR20 highlights? Have a look at our DR20 news item on our website: www.sdss.org/sdss-launche... #DR20

This image highlights the three mappers that make up SDSS-V. On the right we see a nebula in the Milky Way, observed by Local Volume Mapper. In the middle we see a map of all the galaxies and quasars observed by Black Hole Mapper, while on the right we see a map of all the stars observed by Milky Way Mapper.
