Distance from Earth

About 13 billion light-years

Detail

The 100 quasars identified from the Hyper Suprime-Cam (HSC) data. The top seven rows represent the 83 new discoveries, while the bottom two rows represent 17 previously known quasars in the survey area. They appear extremely red due to the cosmic expansion and absorption of light in intergalactic space. All the images were obtained by HSC. (Credit: NAOJ)
