Lynx Arc

The Lynx Arc was discovered in 2003 and is considered to be the hottest known star-birthing region in the Universe as of October 2003. It is located at  08h 48m 48.76s +44° 55′ 49.6″. The Lynx Arc was discovered in 2003 and is considered to be the hottest known star-birthing region in the Universe as of October 2003. It is located at  08h 48m 48.76s +44° 55′ 49.6″. It is located in the constellation Lynx, 12 billion light years away (z=3.357) from Earth, 8 million times farther away and one million times brighter than the Orion Nebula. It contains about 1 million blue stars, while the Orion Nebula only contains 4. The Lynx Arc was found in a systematic search around galaxy cluster RX J0848+4456 (z=0.570), with the help of a gravitational lens, a 4.5 billion light years distant galaxy cluster (CL J0848.8+4455 lying at z=0.543). Amongst others the Keck Observatory, the Hubble Space Telescope and ROSAT participated in the search.
