image: This is a color image of Sw 1644+57 created from X-ray (Chandra X-ray Observatory, blue), near-infrared (Hubble Space Telescope, green) and mid-infrared (Spitzer Space Telescope, red). The object is unique in emitting strongly at all of these wavelengths, and clearly stands out from other objects in the field. This image relates to an article that appeared in the June 16, 2011, issue of Science Express, published by AAAS. The study, by A.J. Levan at University of Warwick in Coventry, UK, and colleagues was titled, "An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy." view more
