If such a supernova exploded close to quasar J1342+0928, debris would then fall towards the galaxy’s centre, eventually becoming incorporated into the quasar.

The NASA/ESA Hubble Space Telescope has captured the first-ever picture of a distant quasar lensed into five images. In addition the image holds a treasure of lensed galaxies and even a supernova.

Astronomers may have discovered the ancient chemical remains of the first stars to light up the universe. Using an analysis of a distant quasar observed by the 8.1-meter Gemini North Telescope, ...

The supernova exploded in a spiral galaxy with redshift = 0.04528, which corresponds to a light-travel time of about 0.6 billion years.In comparison, the quasar at the right has a redshift of 3. ...
