NASA has composed a beautiful melody that represents the cosmic collision between two galaxies.
The blocked lenticular galaxy NGC 274 Spiral galaxy NGC 275, known collectively as Arp 140, is in the process of merging to form a single new structure. After such a collision, the mixture of interstellar material would trigger a wave of new star formation.
New image from NASA Hubble Space Telescope Captures interaction Galaxies, with NGC 274 visible on the right and NGC 275 on the left. Scientists were able to convert image data into music – a process known as data sonification – which was carried out by NASA Subscribed to X (Twitter officially) on January 24.

Use Hubble notes, scientists assigned each color in the image data to an intensity level, where blue light is represented by a higher temperature and red light is represented by a lower temperature. The final musical composition moves from left to right across the picture.
Symphony of #cosmic_collisions! 🎵This pair of interacting galaxies is known as Arp 140. Scientists took the data in this new Hubble image and turned it into music! They assigned the color tone of the image as a whole (blue light higher, red light lower). pic.twitter.com/x0eWj7S1tqJanuary 24, 2024
The higher notes at the beginning of the tune represent blue light coming from NGC 275, likely emitted by bright, newly formed stars as a result of the ongoing stream. Galaxy collision. In comparison, lenticular galaxy NGC 274 doesn't have as much gas and dust as its spiral companion because it's composed primarily of old stars, which is why the tune transitions to lower, more muted tones toward the end.
The two merging galaxies are located in the constellation Cetus, and show different structures. While barred spiral galaxies contain a bright central bar consisting of… starsThe lenticular galaxy has a more elliptical shape and a hazy appearance. Lenticular galaxies also lack the well-defined arms generally seen in spiral galaxies.
“It's usually arms [spiral] “The galaxy begins at the end of the tape.” NASA Officials said in a statement they released the new Hubble image on January 24. “Lenticular galaxies, on the other hand, are classified somewhere between elliptical and spiral galaxies. They get their name from the rim-like, disc-like appearance.”
Despite their differences, both lenticular and spiral galaxies are known to have a bright central bulge and a flat disk. In the new Hubble image, both galaxies are visible face to faceoffering a complete view of its astonishing complexities.
