Here is some updated information about the course:

• We will use Astro Discourse for communication, Q&A, etc.  Now online here: https://astro-discourse.uio.no/c/in3060-25v/571
• There are video recordings of the lecture from spring 2020.  The content has hardly changed, so we are not making new recordings this semester:
