that was encircled by at least three other galaxies in a “galactic knot.” In other words, it appears that the quasar’s galaxy had sucked several others toward it.of the observed quasar-hosting galaxies showed signs of galaxy mergers or encounters in the past.
Only aroundGravity causes massive structures to interact with each other, even in the vastness of space. Whether the collision between the Milky Way and Andromeda will yield a quasar, no human can say for sure. But further observations of these luminous objects could lend a hand to computer models testing galaxy evolution and interaction, so we might learn more about where the cosmos’ most spectacular objects came from.
