Hubble Space Telescope Spots Overlapping Spiral Galaxies
This beautiful photograph from the Hubble Space Telescope shows two spiral galaxies that are overlapping one another. The names of the two galaxies, which are more than a billion light-years away from Earth, SDSS J115331 and LEDA 2073461, are uninteresting. Despite the fact that they appear to collide in this image, the two galaxies' alignment is probably only a result of coincidence; they aren't really colliding. These two galaxies might just be passing ships in the night, but Hubble has previously photographed a stunning array of interacting galaxies.
One of many NASA/ESA Hubble observations exploring key aspects of the Galaxy Zoo project is this image. The Galaxy Zoo project, which began in 2007, and its offshoots are enormous citizen science initiatives that crowdsource galaxy classifications from a pool of hundreds of thousands of participants. These volunteers categorize galaxies that robotic telescopes have captured, and they frequently are the first people to ever see an astronomical object.
Volunteers working on the initial Galaxy Zoo project found a variety of strange and amazing galaxies, such as rare 3-armed spiral galaxies and colliding ring galaxies. The project's coordinators requested Hubble time to observe the most peculiar residents of the Galaxy Zoo, but in keeping with the project's beginnings in crowdsourcing, the public chose the list of targets.
