A couple of weeks ago one of my friends received Da Vinci and Ramanujan sun badge. I was pumped I could not wait to earn it. So I completed the task and earned 2 million energy points. But I did not receive it. Apparently, they were was retired. I am not sure why it was removed but I was certainly looking forward to earning it.
Why was the majority of the sun badges removed?

Hello!
About 50 of the badges were recently retired because of the code and data queries that were required to keep them active. Khan Academy is currently undergoing a major change - the code base is being transferred from Python 2 to GO language. Retiring these badges was necessary in order to clean up the code and free up space for new features.
