[TOMT] [Youtube Video] Im looking for a video that talks about pulsars, like the unknown pleasures album cover by joy division.

My friend has a joy division, unknown pleasures album cover shirt and I had watched this video on youtube about pulsars but i cant find it. I remember the video title was maybe something alluding to the most strange sound from nature, but i remember is specifically didnt say the word pulsar. I remember the start of the video is a black screen and then the sound of a pulsar starts playing. For each pulse a line is drawn across the screen, ofc drawing the image that is famous for being the unknown pleasures album cover. The album cover is not the main focus but the video does make a little joke about it in the end. He goes on to lightly explain pulsars, saying they are spinning stars emitting radio waves. I remember the video not being super long or in depth, maybe no longer than 10 minutes. I remember the animation being real good, kinda like those other channels like fern and Shortary maybe.

This video has been recommended to me at random times but multiple times, i cannot remember the thumbnail at all right now.
