The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) consists of astronomical cameras and telescopes that survey the sky for moving and variable objects on a continual basis, producing accurate astrometry and photometry. It is located at Haleakala Observatory, Hawaii, US.

Pan-STARRS1 (PS1) is the first part of Pan-STARRS to be completed and is the basis for both Data Releases 1 and 2 (DR1 and DR2).  The PS1 survey used a 1.8 meter telescope and its 1.4 Gigapixel camera to image the sky in five broadband  filters (g, r, i, z, y). Peranso allows to plot light curves from the PS1 data release DR2 (2019, Jan 28). At 1.6 petabytes, it is the largest volume of astronomical data ever released.

The Pan-STARRS1 Surveys (PS1) and the PS1 public science archive have been made possible through contributions by the Institute for Astronomy, the University of Hawaii, the Pan-STARRS Project Office, the Max-Planck Society and its participating institutes, the Max Planck Institute for Astronomy, Heidelberg and the Max Planck Institute for Extraterrestrial Physics, Garching, The Johns Hopkins University, Durham University, the University of Edinburgh, the Queen's University Belfast, the Harvard-Smithsonian Center for Astrophysics, the Las Cumbres Observatory Global Telescope Network Incorporated, the National Central University of Taiwan, the Space Telescope Science Institute, the National Aeronautics and Space Administration under Grant No. NNX08AR22G issued through the Planetary Science Division of the NASA Science Mission Directorate, the National Science Foundation Grant No. AST-1238877, the University of Maryland, Eotvos Lorand University (ELTE), the Los Alamos National Laboratory, and the Gordon and Betty Moore Foundation.
