Besides being a researcher in the field of astrophysics for 20 years, I have also been a science communicator for 15 years. It s my feeling that in that time none of my efforts, and those include organizing science festivals and researchers night attended by 25k visitors, have resulted in such an impact as my TikTok educational astronomy profile (Dr Cosmic Ray) has. In this talk I will present some main benefits and potential that TikTok and similar platforms have for astronomy education in digital space.
