 Greetings and welcome to the Astronomy Picture of the Day podcast. Today's picture for March 25th of 2024 is titled Sonified, the jellyfish nebula supernova remnant. So what do we see here? Well here we see the remnant of a supernova out in space. Now a supernova occurs when a star explodes and expels material out into space and that's what we're seeing here is the expansion of that material. However, you'll note that this is actually a video and I'm going to play it in a moment and what it is is it is turned into sound. So how can you understand this if you're not seeing the image? Well we can convert the different colors to different tones of sound and that's what you'll see is a line passing through from top to bottom of the image and it is going to convert the different colors into sounds using the sound of a drop of water in honor of the jellyfish nebula so water being appropriate there. Now when we see the reddish glow we're going to get a low tone green is going to give you a middle tone and blue is going to give you a relatively high tone and those correspond in this image to different colors. So the x-ray is in the blue and again that will be the very high pitch the optical is in the red which will be the lower pitch and the radio waves will be in the green colors and that will be the middle pitch. So as we play that we'll be able to sear a little bit of what the nebula would be like using that kind of coding. So let's go ahead and play the video here for a minute and then we'll see what we get. As you've heard there are different tones that occur over the course of about the 30 seconds it takes to play through the video and for the line to scan from the top to the bottom of an image. So a way to be able to understand the image to some extent even if you cannot see the image. Now here we see this as again a supernova remnant which is slowly dispersing out into space that material has been expanding for tens of thousands of years and that material will eventually dissipate. At the center there is a neutron star which forms when a massive star collapses inward on itself forming a very dense core about the size of a city and that will remain forever. So that will stay there for the rest of the time that the universe is around. So here we get to see an example of sonification I should say see and hear an example of sonification turning a visual image into sound. So that was our picture of the day for March 25th of 2024. It was titled sonified the jellyfish nebula supernova remnant. We'll be back again tomorrow for the next picture previewed to be Comet Tales. So we'll see what that is about tomorrow and until then have a great day everyone and I will see you in class.
