NASA has revealed its own "festive lights", and they come from two galaxies that were imaged colliding together. Both NGC 2207 and IC 2163, located approximately 130 million light years from our planet in constellation Canis Major, are spiral galaxies that were caught getting close with each other. The result was exceptionally bright X-rays captured by different hardware and assembled into a single stunning composite image.
NASA released the image on Thursday, explaining that the two aforementioned galaxies are both spirals, as well as detailing the process that causes matter to fall towards either a neutron star or black hole. As it "falls", the matter becomes extremely heated and results in X-rays.
