Astrophysicists at the National Radio Astronomy Observatory (NRAO) have collected data from a variety of devices to generate a stunning compound image of crashing galaxy clusters mutually identified as MACS J0717. MACS J0717 is about 5.4 billion light years away from Earth in the Auriga constellation. The composite makes this the record well-studied galaxy cluster, and the photo was issued at the 224th Meeting of the American Astronomical Society. The background of this stunning image was taken by NASA’s Hubble Space Telescope and captures wavelength spectra covering near ultraviolet, visible, and near infrared. The blue light in the image characterizes x-ray wavelengths, captured by the Chandra X-Ray Observatory. Radio waves are displayed in red, and were made by NRAO’s Very Large Array.

The blue and red areas symbolize several of the most sensitive images ever collected by these instruments, and the radio waves exposed outcomes that were pretty amazing. The lined red region with a light-colored dot in the mid is essentially a black hole with jets of particles being blast out in both directions. The rough red region in the lower left corner is supposed to be a radio galaxy being drained into this powerful cluster of collisions.
The distorted red area is the most thrilling, as it is assumed to specify particles that interrelate with magnetic fields throughout the collisions, with radio waves being released as a consequence. Astrophysicist Reinout van Weeren of the Harvard-Smithsonian Center for Astrophysics told NRAO "The complex shape of this region is unique; we've never spotted anything like this before. The shape probably is the result of the multiple ongoing collisions.” MACS J0717 is one of the hugest and massive known galaxy clusters, creating it a general aim for astronomers. Its size and distance also marks it the major known gravitational lens, which can curve light round it and is very beneficial when studying more distant celestial bodies along with dark matter.
MACS J0717’s lensing power will also be used by the Frontier Fields task for the Hubble Space Telescope. It will capture the area in both visible and near infrared wavelengths. Imaging will take place twice, first in September-November of current year and once more in February-May of 2015. This will let Hubble’s cameras to collect facts from the galaxy cluster beast and neighboring parallel field, detecting the most distant areas of cosmos to date.
