Interested in helping astronomers classify pictures of distant galaxies from earlier in the Universe’s history? Check out the dawn of Galaxy Zoo’s newest iteration: Galaxy Zoo: Cosmic Dawn!

Galaxy Zoo is the most popular project on the Zooniverse, asking volunteers to classify images of galaxies based on their visual appearance. Galaxies have a variety of shapes, from ball-like ellipticals to those with grand spiral arms, so studying how they form and evolve over cosmic time requires classifying large numbers of them: that’s where you come in!

This week, Galaxy Zoo begins its latest incarnation, Galaxy Zoo: Cosmic Dawn, with tens of thousands of new galaxy images now available for you to help classify! These were taken by the Hyper Suprime-Cam (HSC) on board the 8.2m Subaru telescope on the summit of Mauna Kea in Hawaii, as part of the Hawaii Two-0 (H20) survey.

Compared to previous incarnations of Galaxy Zoo, H20 enables us to see fainter and more distant galaxies from earlier in the Universe's history. This deeper imaging also means we can observe many more distant galaxies in the same patch of sky, so the images you will see may often appear redder and blurrier than you might expect. H20 is a key component to the more ambitious Cosmic Dawn survey, aiming to push the boundaries of extragalactic astronomy by studying galaxy evolution out to a few hundred million years after the Big Bang!

There are also some rare types of galaxies that we don't want to miss, so make sure to check out the Tutorial!
