NASA Image of the merger of clusters galaxies looks suspiciously like USS Enterprise

The current understanding of humanity in physics may indicate a faster journey than light, but researchers here on Earth can still occur in places far too far to ever visit (and usually only how they looked in the distant past). One of them is a galactic collision, which, at least from our planetary point of view, looks like a vessel where no one has disappeared before.

NASA released the above complex image of the Abell 1033 galaxy cluster about 1,600,000 light-years away from this week, showing a wps of gas that seemed to be arranged in the form of Star TrekOf USS Enterprise. NASA wrote that the image was captured by Chandra X-ray observatory, an X-ray telescope that detects heated gases, as well as the low-frequency array, which detects radio emissions.

The image may look relaxed, but it is the result of a cosmic phenomenon releasing huge amounts of energy. Galaxies of galaxies are collections of galaxies that are the largest known bodies held together by gravitational forces, containing both galaxies and much larger amounts of heated gas. According to NASA, Abell 1033 is actually two clusters of galaxies that are in the process of colliding with each other, producing "swirls and shock waves." NASA added that the two clusters are working with a supermassive black hole that produces planes of rapid particles that appear as emissions radio:

Abell 1033 collided with another energetic cosmic process – the production of high-velocity particle jets by a material winding into a supermassive black hole, in this case found in a galaxy in one cluster. These jets are detected by radio emissions on the right and left sides of the image. The radio emission is generated by electrons winding around magnetic field fields, a process called synchrotron emission.

The electrons in jet planes move at a speed very close to the speed of light. As the galaxy and its black hole moved toward the bottom of the picture, the plane on the right slowed the rate of collision with hot gases in the cluster of the other galaxy. The plane to the left did not slow down, because it encountered much less hot gas, giving a distorted appearance for the planes, rather than the straight line that was usually seen.

NASA added that radio emissions coming from the cluster would usually lose most of their energy while radiating, and could not be detected, although "the extensive expanded radio emission in Abel 1033, which extends over about 500,000 light-years, suggests that intense electrons are in quantities Larger and higher energies than previously thought ":

Other sources of radio emission in the picture besides the star-shaped object are shorter planes than another galaxy (labeled "short jets") and "chicken radio" consisting of a cloud of electrons which faded in radio emission, but then the shock waves reenergized were compressed into the cloud. This caused the cloud to shine again on radio frequencies, as we reported back in 2015.

Researchers from the University of Leiden, the Institute of Radio Astronomy, the University of Hamburg and the Max Planck Institute for Astrophysics, published the findings of the study in Science Advances.
