banner of Exploring the Universe with Subaru Telescope Data

Hyper Suprime-Cam (HSC), mounted on the Subaru Telescope located at the summit of Maunakea, on the Big Island of Hawai‘i, has been in operation since 2013. It is an epoch-making giant digital camera with an extremely wide field of view.
The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), an extensive survey program with HSC, started in 2014 and the first HSC-SSP dataset was released to the public in February 2017. Using the “HSC Viewer,” why don’t you explore the Universe observed by the Subaru Telescope?


The HSC Viewer was developed based on "hscMap," the data-handling application for researchers.
