Breathtaking image of galaxy cluster made with X-ray and radio data

A structure in the heart of the Perseus galaxy cluster can now be seen as an otherworldly display of reds and blues thanks to a new technique that involves X-ray and radio data.

This technique merges radio data from the LOFAR (Low Frequency Array) radio telescope array and X-ray data from NASA’s Chandra X-ray observatory. Using both to create a composite image not only produced this new image, but, more importantly, told a team of astronomers more about the origins of the enigmatic structure.
