Scientists have been observing two ultra brilliant pair of spiral galaxies some 130 million light years away colliding into each other, and turning into a dazzling cosmic show.

The spiral galaxies NGC 2207 and IC 2163 in the constellation Canis Major collided some 40 million years ago and are now spawning hot, young stars at an extremely rapid rate.

Across the known universe, these two galaxies emit the brightest and most massive super bright X-ray objects called "ultraluminous X-ray" (ULX) sources. These X-rays have been picked-up by NASA's Chandra X-ray Observatory.

These two galaxies hold intense amounts of bright X-ray sources called X-ray binaries. These X-ray binaries are produced when a normal star orbits around a collapsed star that could be a neutron star or even a black hole.

The extreme gravitational forces from the collapsed star sucks out the energy from the normal star in a process called accretion. This produces heat to a million degrees that generates a massive amount of X-rays.

ULXs are extremely bright when they emit large amounts of radiation from their X-rays compared to millions of suns measured at any wavelength. ULXs are also extremely rare.

Most galaxies don't have ULXs, including the Milky Way but some galaxies usually have one. NGC 2207 and IC 2163 have 28 ULXs.

These galaxies present a strong link between X-ray sources and the fast rate of how stars are born. X-ray sources concentrated into spiral forms inside the galaxies can be conducive to the formation of stars.

The study also suggests the other stars are also very young, about 10 million years old.

This study was published in the Astrophysical Journal.
