      Joy Division’s debut album in 1979… “Unknown Pleasures”. Giving some insight into the title of this post.

      Like the other amigo said, it’s detected emissions from a pulsar. For some more explanation, pulsars spin really fast and emit radio waves, think of it sorta like a lighthouse. So what the image is measuring is the intensity of the radio waves from this pulsar as it spins, with each period stacked in front of the last.

      Visual aid from Wikipedia:

      Your browser does not support playing HTML5 video. You can download a copy of the video file instead.

      As you can see, this one has been simplified to demonstrate the concept, and the actual data is much more varied and interesting to look at; I do not know what causes the peak offsets and would also like an explanation

        with each period stacked in front of the last.

        Yeah, that part is confusing because the description says

        Time increases … toward the top …

        Which would mean the oldest pulse is in the foreground.

          ahh you’re right, I see, a little counter intuitive since going front-to-back would obscure newer data that wont be seen at all, while going back-to-front would only obscure older data

      I didn’t know either so I looked it up, apparently it was the first detected radio pulsar, briefly thought to be an extra terrestrial transmission…and later used on Joy Division album cover: https://en.m.wikipedia.org/wiki/PSR_B1919%2B21

    didn’t know the album cover was from a pulsar. I’d heard a story it was some kind of ECG trace of a heart attack / someone dying.

      The pleasure is unknown… or is it?

        Here is an alternative Piped link(s):

        or is it?
