Quasar gives glimpse of early uni­verse

The Free Press Journal - - WORLD - AGEN­CIES /

Sci­en­tists have iden­ti­fied an ex­tremely dis­tant quasar that may pro­vide a glimpse into the early his­tory of the uni­verse.

A quasar is a mas­sive and ex­tremely re­mote ce­les­tial ob­ject, emit­ting large amounts of en­ergy, and typ­i­cally hav­ing a star­like image in a tele­scope.

Astronomers, us­ing ob­ser­va­tions from Gem­ini Ob­ser­va­tory, de­tected the light emit­ted from the dawn of time thanks to a fore­ground galaxy act­ing as a grav­i­ta­tional lens, which mag­ni­fied the quasar's an­cient light. The Gem­ini ob­ser­va­tions pro­vide crit­i­cal pieces of the puzzle in con­firm­ing this ob­ject as the bright­est ap­pear­ing quasar.
