Description
The Telescope Array is the largest ultra-high-energy cosmic ray (UHECR) observatory in the Northern Hemisphere. It consists of 507 surface scintillator detectors covering approximately 700 square kilometers and three fluorescence telescope sites overlooking the surface array. The aim of the Telescope Array is to explore the origin and nature of UHECR by measuring the energy spectrum and the distribution of arrival directions and mass composition of UHECR. Here the recent results of the Telescope Array are presented. In addition, we have two ongoing extensions: one is the extension for the highest-energy cosmic rays towards four times the Telescope Array and the other is the Telescope Array Low-energy Extension to explore the transition from galactic to extragalactic cosmic rays. The prospects of these extensions are presented.
