Webb’s View of the Extremely Red Quasar SDSS J165202.64+172852.3

The quasar SDSS J165202.64+172852.3 is depicted here by the NASA/ESA/CSA James Webb Space Telescope to demonstrate the distribution of gas around the object.

The quasar is an “extremely red” quasar that exists in the very early Universe, 11.5 billion years ago.

This image is composed of four narrow-band images made from the Webb NIRSpec instrument’s integral-field spectroscopy mode. 

Each colour illustrates the relative speed of ionised oxygen gas across the cluster. The redder the colour the faster gas is moving away from our line of sight with the quasar, while the bluer the colour the faster it's moving away from the quasar toward us. The colour green indicates that the gas is steady in our line of light in comparison to the quasar.

[Image Description: This visual shows a quasar composed of four narrow-band images together, which appears as a burred rainbow blotch of colours.]
