'Monster' driving cosmic beacon


June 30, 2011 - BBC News
Astronomers have spied a monster black hole - the brightest object yet seen in the early Universe.

Detected by a UK telescope in Hawaii, the hole is seen as it was a mere 770 million years after the Big Bang.

Mauna Kea telescopes find earliest-known quasar

June 29, 2011 - Star Advertiser
An international team of astronomers using telescopes on Mauna Kea have discovered the most distant and earliest-known quasar, a bright, starlike object believed to have formed just after the universe was created.
...
The infrared sky survey was conducted at the United Kingdom Infrared Telescope and confirmed by observations with the Gemini North telescope, both on Mauna Kea in Hawaii. The results are in the June 30 issue of the Journal Nature.

Mauna Kea Telescope Discovers Earliest Quasar

June 29, 2011 - KITV, Honolulu
A team of European astronomers said it has discovered the most distant and earliest quasar yet.
...
The quasar was identified in images from a sky survey taken by the United Kingdom Infrared Telescope perched near the summit of Mauna Kea, Hawaii. It was then confirmed by other telescopes, including the Gemini North telescope, also on Mauna Kea.

It's the brightest object yet of our early universe

June 29, 2011 - MSNBC
Scientists have discovered the most brilliant object yet from the infancy of the cosmos, a super-bright galaxy that challenges notions of how extraordinarily massive black holes evolved.
...
The distance to the quasar was then determined from observations made with the European Southern Observatory's Very Large Telescope and the Gemini North Telescope. Based on how greatly the light from the quasar was stretched during its journey by the expansion of the universe, the scientists estimate the quasar existed only 770 million years after the Big Bang.

Early universe's brightest object detected

June 29, 2011 - CBS News
(Space.com) Scientists have discovered the most brilliant object yet from the infancy of the cosmos, a super-bright galaxy that challenges notions of how extraordinarily massive black holes evolved.

The brilliant enigma is a quasar, a stage that some galaxies go through when lots of material falls into the supermassive black holes at their cores, giving off light as it does so.

Most distant quasar found

June 29, 2011 - Astronomy.com
A team of European astronomers has used the European Southern Observatory’s (ESO) Very Large Telescope (VLT) and a host of other telescopes to discover and study the most distant quasar found to date. This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early universe.
...
The distance to the quasar was determined from observations made with the FORS2 instrument on ESO’s VLT and instruments on the Gemini North Telescope. Because the object is comparatively bright, it is possible to take a spectrum of it, which involves splitting the light from the object into its component colors. This technique allowed the astronomers to find out quite a lot about the quasar.

Most distant quasar raises questions

June 29, 2011 - Science News
Astronomers peering at the early universe have glimpsed the most distant quasar yet. Powered by a black hole of 2 billion solar masses, the quasar appears as it did 12.9 billion years ago, when the universe as we know it today was just beginning to emerge from the Big Bang.
