Classify galaxies on Galaxy Zoo: Euclid - galaxyzoo.org

The new Galaxy Zoo: Euclid project has just launched! If you’re not familiar with galaxy zoo it’s a website where us astronomers ask the public for help classifying the shapes of galaxies in huge datasets taken by survey telescopes. My PhD was made possible thanks to people classifying on galaxy zoo, and I’ve been part of the science team for over 10 years now, so I’m so excited that I get to announce this for you all: that images from the recently launched Euclid space telescope are now up on the site ready to be classified - this data hasn’t been released publicly yet so you will be the very first people to ever see these images from Euclid, and not only that be the very first humans in the Universe to see these galaxies. If you want to know more about Euclid I’ve made a whole video about it before, but essentially it’s goal is to produce images like the Hubble Ultra Deep field but for 2/3 of the entire night sky - essentially the bits where our own Milky Way galaxy isn’t in the way. That’s a lot of data, and labelling that is very difficult. So at Galaxy Zoo, we do have an AI deep learning algorithm called ZooBot sifting through the images first, labelling the easy ones that we already have a lot of examples of from previous surveys, and then the ones the AI is not confident about it shows to users on Galaxy Zoo to get their classifications which help teach the algorithm even more. So this is machines and humans working together in the most efficient way. Your classifications will help us on the Galaxy Zoo and Euclid science teams to answer questions like how has the shape of galaxies changed over time, what are the processes that transform the shape of galaxies, how does the balance of normal to dark matter affect the shape, and so much more. We’ve written a blog post over on the Galaxy Zoo website if you’d like to know more about the project and the link to the Galaxy Zoo: Euclid website is in the video description below - happy classifying!
