Full Dome view: Galaxy Cluster MACS J0717 in Auriga | Hubble Space Telescope
This full dome video shows the galaxy cluster MACSJ0717.5+3745, observed by the NASA/European Space Agency Hubble Space Telescope as part of the Frontier Fields program. Using the effect of gravitational lensing caused by the mass of the cluster, this program allows astronomers to study some of the earliest galaxies in the Universe.
MACS J0717 is located about 5.4 billion light-years away from Earth, in the constellation of Auriga (The Charioteer). It is one of the most complex galaxy clusters known; rather than being a single cluster, it is actually the result of four galaxy clusters colliding.
Due to the huge mass of the cluster it is bending the light of background objects, acting as a magnifying lens. It is one of the most massive galaxy clusters known, and it is also the largest known gravitational lens. Of all of the galaxy clusters known and measured, MACS J0717 lenses the largest area of the sky.
Note: The full dome video display format is designed for projection systems in planetariums.
