Galaxy Hunting: FULL Instructions

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!

Step 1 – The simple theory behind the search for distant galaxies

This short video explains the theory behind the hunt for distant galaxies. You will learn how astronomers at Lancaster and throughout the World use redshift, telescopes and the Lyman Break to make exciting discoveries about the early Universe.

Step 2 – Download the images from the Subaru telescope and the program

Next, let’s download all of the files needed. Below you will find the images you will use to find the distant galaxies, and the written instructions of how to complete the task.

The program you will be using is called SAOImage DS9, or just DS9 for short. Download it and follow the instructions. Don’t worry if you have never used DS9 before, the video below will explain everything!

Step 3 – Find CR7 and new distant galaxies: make your own discoveries!

Now let’s find some super-distant galaxies! In this video you will find everything you need. Enjoy becoming a distant galaxy hunter and then tell us all about what you found!

Step 4 – Tell us about the galaxies you have discovered

Now that you have found the distant galaxies, let us know! Fill in the Google Form with your answers and ask professional distant galaxy hunters a question!
