Happy Birthday Hubble

Happy Birthday Hubble! 

On April 24th 2020 we celebrated the 30th Birthday of the Hubble Space Telescope. Hubble was the first telescope to observe from space and has given us some of the best images of the Universe ever observed.

Activity: Counting Stars

There are lots of stars in the night sky, far more than you could possibly count. The number of stars you can see will depend on the amount of light pollution in your area, if you have lots of street lights and cars you will see fewer stars than if you were out in the countryside. This week is also International Dark Sky Week, April 19-26, so why don't you turn off the lights and get counting! 

You can estimate the total number of stars visible in the sky by counting the stars you can see in a small patch of the sky, then multiplying that number by the total number of patches that make up the whole sky. These instructions take you through this step by step.

Activity: Weighing the Universe at Home

If you have completed the first activity, you will now know how many stars there are in the night sky. However, it is impossible to count all the stars in all the galaxies in the Universe, but we can make a reasonable estimate. To do this, we try to count everything in a small patch of the sky and scale up to the whole sky. Instead of using our eyes we can use a special observation taken by the Hubble Space Telescope called the Hubble Deep Field. Follow these instructions to Weigh the Universe at Home. 

Activity: What did Hubble See on Your Birthday? 

Hubble observes all day, every day. Find out what Hubble looked at on your birthday (leads to NASA website activity). Share your images with us #ShowTheNSO #Hubble30



NASA have published an article called Four Successful Women Behind the Hubble Space Telescope's Achievements. You can read all about Dr. Nancy Grace Roman, the “mother of Hubble, Astronaut Dr. Kathryn D. Sullivan, US Senator Barbara Mikulski and Dr. Wendy Freedman, four amazing women who contributed to the success of the Hubble Space Telescope project.
