XGAL-DIY: Make Your Own Discoveries

Explore the Universe and make your own Astrophysics discoveries with real data from the largest telescopes in the World (and in space!), guided by professional Astrophysicists and step-by-step youtube videos from Lancaster University!

The XGAL Astrophysics group at Lancaster University’s Physics Department is excited to share a number of Astronomy & Astrophysics educational activities for both teachers and students, based on several master-classes and CPD activities we have been running over the years.

Use real data to discover the brightest galaxy in the early Universe (CR7) discovered by our scientists at Lancaster. Once you find it, use your knowledge to discover new galaxies, some of which you might be the first to spot! Tell us about what you found and get in touch with our Astrophysicists, including to ask any further questions, and we will get back to you! Find this activity here

Learn to slice the Universe in cosmic time, map the Universe in 3D and study 4,000 primordial super-distant galaxies discovered at Lancaster, found when the Universe was in its infancy

Learn how Astronomers calculate the redshift and how that can tell us about how distant a galaxy is, and take your knowledge forward with our guided instructions. Get to make your own 3D map of the Universe with just a few clicks and explore it, rotate it and click on each individual galaxy to know more about it, including getting to see how it looks like with the Hubble Space Telescope! What will you discover? Find this activity here


All activities are fully accompanied by detailed instructions and step-by-step youtube videos and with full solutions. These provide unique opportunity to conduct state-of-the-art research and work individually and in teams to learn more about our cosmic origins. You will learn how distant galaxies are discovered, how that allows us to travel back in time, and how to understand what is going on in such distant galaxies.
