This information says that 4 new galaxies have been identified in our vast universe. It mentions that these galaxies have signs of enhanced star formation. These happens when nearby galaxies crash into each other and they rip apart gravitationally. This causes for dust and other particles to crash causing a creation of bigger stars. Our galaxy the milky way will someday also pass through this process and crash with a nearby galaxy such as andromeda. This makes us think that in the past that maybe the milky way was a result of this event as well. In our vast universe this is probably happening to millions of other galaxies somewhere far away. This shows that stars are constantly being made. It also represents how huge our universe is and that we can not fully appreciate it.
