About 11 billion light-years

Dying galaxies around 10 billion years ago (red objects in the magnified panels) were selected from multi-wavelength observations. This research investigated them using the data of the Cosmic Evolution Survey (COSMOS), which includes the observational data of the Subaru Telescope, Chandra X-ray Observatory, and Very Large Array. The central image shows the COSMOS region. It is a three-color composite of the i-band image from Subaru Telescope/Hyper Suprime-Cam, and J- and Ks-band images from the VISTA telescope. (Credit: NAOJ)
