The most crowded collision of galaxy clusters has been identified by combining information from NASA's Chandra X-ray Observatory, Hubble Space Telescope and the Keck Observatory on Mauna Kea, Hawaii. The system MACSJ0717.5+3745 (or MACSJ0717 for short) is located about 5.4 billion light years from Earth.

Three Lasers and Light Pollution

The Keck I Laser propagating, alongside the Keck II and Subaru lasers. WMKO Engineer Andrew Cooper took over 90 x 1minute exposures from near UKIRT on the summit ridge on May 26. The result has been combined into the attached image and a video. The image combines 23 exposures, each 1 minute long. During the exposure, the Keck II laser is aimed over the camera at the Milky Way's Galactic Center. The image also shows a car driving down the summit road which appears as a stream of light.
