The Lynx Cluster (Ground-Based View, Kitt Peak): Location of Detail in 4m

Super-Sized Star-Birth Region in Early Universe

This is an artist's impression of the biggest and brightest star-birth region seen in the universe to date. The newly identified supercluster contains 1 million ultra-hot stars. Their torrent of ultraviolet radiation illuminates huge placental walls of cold hydrogen gas. For...

The Lynx Arc: Stretched, Magnified Light From a Supercluster of Blue-White Stars

This NASA Hubble Space Telescope image of the Lynx cluster of galaxies shows the doubled image of the red Lynx arc (just right of the center). The mysterious arc is really a distant megacluster of stars lying far behind the galaxy cluster in the northern constellation Lynx. The...

The Lynx Cluster (Ground-Based View, Digitized Sky Survey 2): Location of Lynx Cluster in DSS

This is a 2.5 degree, three-color composite from the Digitized Sky Survey 2 centered on the Lynx galaxy cluster. The blue plate (B) is shown in blue, the red plate (R) in green and the infrared plate (I) in red. The frame shows the outline of the Kitt Peak Mayall 4-meter...

Lynx Arc Zoom and Blend to Artist's Illustration

The Lynx arc is 1 million times brighter than the well-known Orion Nebula, a nearby prototypical star-birth region visible with small telescopes. The newly identified megastar-birth cluster contains a million blue-white stars that are twice as hot as similar stars in our Milky...

Zoom into Lynx Arc Artist's Impression

This is an artist's impression of the biggest and brightest star-birth region seen in the universe to date. The newly identified megastar-birth cluster contains 1 million ultra-hot stars. Their torrent of ultraviolet radiation illuminates huge placental walls of cold hydrogen....

Gravitational Lens Animation: Light Bent by Foreground Galaxy Cluster

The arc is the stretched and magnified image of the megastar-birth cluster about 12 billion light-years away, far beyond the foreground galaxy cluster. This means that the remote source existed when the universe was less than 2 billion years old.

Gravitational Lens Animation: Changing View – Light Bent by Foreground Cluster

The Lynx arc only became visible thanks to the gravitational magnification provided by the nearby cluster of galaxies. The huge mass hidden in the galaxy cluster magnifies and bends the light from the Lynx arc behind it.

Zoom out of the Lynx Arc

The Lynx arc is 1 million times brighter than the well-known Orion Nebula, a nearby prototypical star-birth region visible with small telescopes. The newly identified megastar cluster contains a million blue-white stars that are twice as hot as similar stars in our Milky Way...

Interview with Dr. Robert Fosbury: A Friday Discovery

Dr. Robert A.E. Fosbury, of the European Space Agency's Space Telescope-European Coordinating Facility in Germany, tells how the Lynx arc discovery began. "One Friday afternoon a colleague walked in waving a sheet of paper vigorously. The plot showed a spectrum of a mysterious...

Interview with Dr. Robert Fosbury: Unidentified Spectrum Takes the Team on Two-Year Journey

Dr. Robert A.E. Fosbury, of the European Space Agency's Space Telescope-European Coordinating Facility in Germany, explains how the unidentified spectrum took the team on a two-year journey of discovery.
