The image from the Hubble Space Telescope shows two galaxies that are merging together. The Angel Wing is named after it's shape, which was created as the two galaxies collide.
The image was taken as part of a citizen science project. Members of the public were invited to help with astronomy research by helping to identify and classify different types of galaxies from data collected by telescopes.
Since 2007, 15 different versions of the project have received millions of classifications from the public to help identify bright galaxies, interacting or merging galaxies, other phenomena such as supernovas, and more. Between 2010 and 2012 there was a project focused on comparing older and younger galaxies.
The public was invited to help identify black holes using data from radio telescopes, as part of the RadioGalaxy Zoo: LOFAR project.
If you would like to help out, the follow-up project called Zoo Gems was started by researchers using Hubble. The short gaps in Hubble's schedule were used to take pictures of attractive and interesting objects.
Hubble's Advanced Camera for Surveys took detailed follow-up observations of noteworthy objects from both projects. The targets include ring-shaped galaxies, unusual spirals, and a striking selection of galaxy mergers.
