A captivating image of two interacting galaxies, known as MCG+05-31-045, has been shared by NASA and the European Space Agency (ESA) through the Hubble Space Telescope. It is located 390 million light-years away in the Coma Cluster. The smaller galaxy's spiral arms appear to merge with the larger one, with a tail of material and a halo connecting the two, suggesting an ongoing collision that could eventually transform their structure entirely.

The Coma Cluster: A Rich Galactic Collection

The Coma Cluster, home to this galactic interaction, is a dense collection of over a thousand known galaxies. While most are elliptical in shape, these forms are typically created by gravitational interactions such as collisions. During these events, the structure of spiral galaxies is disrupted, and their gas is compressed, sparking bursts of new star formation. Once the massive blue stars exhaust their energy and die out, the galaxies are left with cooler, redder stars and little gas to sustain further star formation. Over time, such interactions result in the formation of elliptical galaxies.

The Future of MCG+05-31-045

Scientists believe that the same transformation is underway for MCG+05-31-045. As the smaller galaxy merges into its larger neighbour, gravitational forces will trigger intense star formation. This phase will not last indefinitely. Once the hot, massive stars die out, the resulting structure is likely to resemble the elliptical galaxies prevalent in the Coma Cluster. Despite the dramatic changes, this process will unfold over millions of years.
