How to Download Raw Data from the James Webb Space Telescope - Tutorial

Updated: Jun 7, 2023

The James Webb Space Telescope is now producing incredible images of deep sky objects! NASA being such an awesome group of people, allow anyone to download all the data that the JWST produces... for free!

Downloading the data is a little tricky though... there is no big "Download" button anywhere on the page, and you'll have to fiddle with some code to be able to download the data. Let me tell you that I know nothing about coding and that I am terrible at using the Terminal, yet, I was able to get it to work, so you can do it too!

⚠️ Update: There now is a much easier way to download the data that does not involve the Terminal. Scroll down to learn more.

Thank you so much to my friend Patrick for helping me with this! You can follow Patrick on Astrobin to see his awesome images.

Update: An Easier Way to Download the Data

  • First, go to to visit the page where the data is hosted.

  • Click on Advanced Search. It will open a window.

  • In the “Mission” box, type “JWST” if you’d like to download data from the James Webb Space Telescope. Press Enter so that the records update.

  • The easiest way to find an object you are looking for is to input its designation in the “Target Name” box. In Our case for the Carina Nebula, we’ll input “NGC 3324”. If you do not know your target’s designation, you can play with any of the other filters to find exactly what you are looking for.

  • Press “Search”.

  • On the left under “Instruments”, only let NIRCAM checked. You should now only have a few rows left, normally one for each filter used. In our case, six.

  • Click on the download icon on the left of each row to download the data.
