A new astronomical dataset known as the second data release of the Dark Energy Camera Plane Survey (DECaPS2) has revealed 3.32 billion objects in the Milky Way galaxy, the largest catalog compiled to date. The survey took two years to complete and was captured by the Dark Energy Camera (DECam) instrument on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile. DECaPS2 is a survey of the plane of the Milky Way as seen from the southern sky taken at optical and near-infrared wavelengths, and covers 6.5% of the night sky. The dataset is available to the entire scientific community and is hosted by NOIRLab's Astro Data Lab.
