\fFrom the description of the photograph from APOD: Spiky stars are nearbyLinks to an external site., but fuzzy galaxies are strewn far across the Universe in this cosmic viewLinks to an external site.. Spanning about 1/2 degree on the sky, the pretty picture is the result of astronomer Johannes Schedler's project to look back in time, toward a quasar 12.7 billion light-years awayLinks to an external site.. The quasarLinks to an external site.is just visible in the full resolution image at the position marked by short vertical lines (center). The intrinsically bright nucleus of a young, active galaxy powered by a supermassive black hole, the quasar was recentlyidentifiedLinks to an external site. as one of the most distant objects knownLinks to an external site.. Since light travels at a finite speedLinks to an external site., the galaxies receding into the distance are seen as they were in the increasingly remote past. The quasar appears as it did about 12.7 billion years ago, when the Universe was just 7 percent of its present ageLinks to an external site.. Of course, the expansionLinks to an external site. of the Universe has redshiftedLinks to an external site. the light. Schedler added image data extending to the near-infrared, acquired by collaborator Ken Crawford, to detect the distant quasar, with a measured redshiftLinks to an external site. of 6.04. e The redshift of this quasar is measured to be 6.04. Is that a large or small redshift (You may want to look up the redshifts of a nearby galaxy and a far away galaxy for comparison)? What does it imply about the distance to the quasar? e How can astronomers tell the difference between a star and a quasar
