JAMES WEBB SPACE TELESCOPE IS REVEALING SURPRISING SECRETS ABOUT A MASSIVE AND EXTREMELY REMOTE SPACE OBJECT

MICAH HANKS·JULY 8, 2024



Observations by the James Webb Space Telescope (JWST) have provided astronomers with unprecedented new insights into the early universe, thanks to detailed imagery of the quasar PJ308–21 recently obtained by NASA’s premier space observatory.

The new imagery reveals the appearance of this celestial object as it would have looked when the universe was less than a billion years old, offering a detailed view of the quasar’s spectrum and host galaxy.

Obtained with Webb’s NIRSpec instrument, the new imagery of quasar PJ308–21 reveals its spectrum with an uncertainty of less than 1% per pixel despite the object’s incredible distance. Data collected by Webb reveals that the quasar’s host galaxy and satellite galaxies show indications of dynamic processes that include photoionization.

One of the satellite galaxies showed low proportions of elements other than hydrogen or helium, which astronomers call metallicity, while another was revealed to possess higher metallicity and signs of partial photoionization from the nearby quasar.
