This image is one of many observations made by the NASA/ESA Hubble telescope to delve into the highlights of the Galaxy Zoo project. The Galaxy Zoo project was originally established in 2007, and its follow-up is a large-scale citizen science project that crowdsourced galaxy classifications from hundreds of thousands of volunteers. These volunteers sort the galaxies imaged by the robotic telescope and are often the first to see the celestial objects.
Over the course of the original Galaxy Zoo project, volunteers discovered a number of bizarre galaxies, including unusual three-armed spiral galaxies and colliding ring galaxies. The astronomers coordinating the project applied for Hubble time to observe the most unusual “inhabitants” of the “galaxy zoo” — but true to the project’s crowdsourced roots, the list of targets was decided by a public vote.
