Hear the hypnotic sound of two galaxies dancing through an image obtained by the Hubble telescope

Image sonification is increasingly popular at NASA

When we talk about space telescopes , such as the powerful James Webb , we are certain that we are going to enjoy a visual spectacle that will amaze us and that could be the starting point for new NASA missions or others. space agencies. However, we rarely think about how these images could be translated into cosmic sounds .

The Hubble telescope sponsors this cosmic dance

The image that you can see in the NASA publication, which we leave you below these lines, has been obtained by the Hubble space telescope . In it we can see a pair of galaxies , one of them of the barred spiral type and the other lenticular, which are interacting with each other and whose group has been called Arp 140 .

The lenticular galaxy , which appears on the right of the image, is called NGC 274 , while the barred spiral galaxy on the left is called NGC 275 . Both are located in the constellation Ceto , also known as the Whale or the Sea Monster.

However, for those of us who are not experts in astronomy, this cosmic spectacle without any type of context or explanation would be nothing more than another beautiful image of a couple of galaxies in our universe. And this is where the term sonification comes in .

This way of enjoying outer space is being explored by NASA on its website , who describes sonifications as digital data that is transformed into images and, finally, translated into sounds . We are not talking about the sound of space, but about the translation of what the Hubble telescope captures .

And in this case, as you can hear in the publication that we leave you on these lines, we have the opportunity to listen to the image that shows the interaction of the galaxies NGC 274 and NGC 275 , which could be described as the cosmic dance between two lovers with millions of years behind them.

NASA explains in the video published on YouTube that each color in the image has a tone assigned as a whole, so if an area has a lighter blue color, the tone will be higher and if, for example, an area is more intense in red, the tone will be lower. Additionally, larger objects generate lower pitches and smaller objects will produce higher pitched sounds . The brighter the light, the more volume the composition will achieve.
