Spectacular Image: Hundreds Of Galaxies On An Collision Course

Far away from Earth, the ongoing collision of dense galaxy clusters is creating a stunning show of radio waves. In the region, where clusters of hundreds of galaxies are colliding, these variety of objects are visible only to radio telescopes. Scientists created a ‘true colour’ image of the region to reveal what it would look like if humans could see radio waves, rather than just visible light.
Researchers at the National Radio Astronomy Observatory (NRAO) made the image using the Karl G. Jansky Very Large Array (VLA) in New Mexico.

Abell 2566

Researchers have released an amazing image of Abell 2566. In the annotated image (move the slider to see the markings), the point sources (examples in red) are galaxies like ours. Blue objects are radio galaxies with streams of plasma, and in green is the ‘Large Relic’, which could be a shockwave as the clusters collide.
