JAMES WEBB TELESCOPE CAUGHT TWO COLLIDING GALAXIES, BUT RESEARCHERS FOUND SOMETHING UNUSUAL THERE

While observing this image researchers from the California Institute of Technology have found something unexpected, they are expecting that both the galaxies do not have an active supermassive black hole at their center. Most massive galaxies have an active supermassive black hole at their center, but by analyzing data from IC 1623 researchers did not find any evidence of supermassive black holes at the center of both galaxies. However, the researchers are saying maybe those supermassive black holes are not active for some reason or could be hidden within the mass of the galaxies smashing together. Our milky way has an active supermassive black hole at its center, and we have even captured an image of this supermassive black hole.
The collision between two galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring.
"A merger brings dramatic changes to the galaxy's shape content and pretty much everything, so we really have to understand this process to figure out how galaxies evolve," says Vivian U at the University of California, Irvine, part of the team conducting this research.
Four billion years in the future, our galaxy, the Milky Way will collide with another galaxy, called Andromeda. Although two galaxies will pass through each other at a million miles an hour. The whole process will take many millions of years to complete. And when everything settles down, the two galaxies will have merged into one.
