NASA/ESA Hubble Space Telescope photographed two overlapping spiral galaxies - SDSS J115331
Even though they appear to be colliding in this image, the two galaxies aligned most likely by chance. Astronomers claim that they do not actually interact.
This image is one of many sightings.Hubble as part of the Galaxy Zoo project. Let's remember that Galaxy Zoo is an online project to classify different types of galaxies. It helps classify more than 60 million galaxies imaged by the Sloan Digital Sky Survey project. Part of a group of citizen science projects. The project was created after the success of the Stardust@Home project. As part of the project, volunteers classify galaxies captured by automated telescopes.
During the original Galaxy Zoo projectVolunteers have already discovered a menagerie of strange and wonderful galaxies. The astronomers coordinating the project applied to use Hubble's time to observe the most unusual inhabitants of the "galactic zoo", but, in keeping with the project's crowdsourcing roots, the list of targets was chosen through a public vote.
