After the small galaxy falling through the disk and reach the other side, creating an expanding ring that expels gas and form new stars

Astronomers at the University of Oxford found Arp 147, a system of galaxies, formed by a ring collided created by the gravitational attraction of a young galaxy using the Hale telescope, said the Royal Astronomical Society (RAS).
The strange ring, identified by the blue light spectrum that captures the integral field spectrograph telescope and the galaxy, there are 440 million light years from Earth in the constellation Cetus.
The ring was once a giant galaxy like our Milky Way, but the small intruder galaxy crashed causing its gravitational pull than push to the stars and gas through its center.
After the small galaxy falling through the disk and reach the other side, the stars and the gas outside reborn, creating an expanding ring that expels gas and form new stars.
