Herschel-ATLAS Gravitational Lenses

A team using Herschel have discovered a new way of locating a natural phenomenon that acts like a zoom lens, allowing astronomers to peer at galaxies in the distant and early Universe. The magnification created by this phenomenon allows astronomers to see galaxies otherwise hidden from us, providing key insights into how galaxies have changed over the history of the cosmos.

The Galaxy Cluster Abell 2218 is so massive that it magnifies and distorts images of faraway galaxies that appear as 'arcs' throughout the picture.

Amazing new data captured by ESA's Herschel Space Observatory - carrying the largest mirror ever launched into space - have just been publicly released, allowing the World's astronomers to share in the Herschel SPIRE instrument's observations of distant galaxies. From its vantage point nearly 1.5 million km from Earth (1 million miles), the Herschel spacecraft has given astronomers new insights into the different types of galaxy in the distant Universe and will allow them to explore part of the Universe as it was some eleven billion years ago or just 3 billion years after the Big Bang.
