The Hubble Space Telescope has recently made a remarkable discovery near the constellation Draco: a peculiar pair of galaxies known as Arp 142. The galaxies, known as NGC 2936 and NGC 2937, are located approximately 140 million light-years from Earth and have been gravitationally distorted by their close proximity to each other, a phenomenon known as ‘tidal interaction.’ The two galaxies have been pulled and stretched into their current shapes, sparking a brilliant display of star formation around their edges. The Arp 142 pair is an example of a highly dynamic and ever-changing cosmic environment, and Hubble’s incredible resolution has allowed us to peer into its peculiar structure and learn more about the evolution of galaxies in the universe.
