Arp_220 is a unique galaxy located about 250 million light-years away in the constellation Serpens. It is classified as a starburst galaxy, meaning it is experiencing an intense period of star formation. This activity is primarily due to the interaction and merging of two galaxies, which creates conditions favorable for new stars to form rapidly. The galaxy is notable for its bright infrared emissions, which are a result of the dust and gas being heated by the newly formed stars. Arp_220 is one of the closest examples of a merging galaxy, providing valuable insights into the processes of galaxy evolution and star formation in the universe.
