Although the two galaxies have their separate names, they also have the common name of Arp 91 due to their proximity to each other. NASA has stated that the lower galaxy, which looks like a bright spot, is NGC 5953, and the oval shaped galaxy in the upper right is NGC 5954. In reality, the two are spiral galaxies, but their shapes look very different. because of their orientation relative to Earth, according to NASA. However, although the galaxies appear tango, they are located more than 100 million light years from Earth.
Captioning their Instagram post, the agency explained that the lower galaxy, NGC 5953, is clearly pulling at the galaxy in the upper right, which appears to be extending an arm spiraling downward. In addition, their shapes appear strange due to their orientation relative to the Earth but are classified as spirals. Scientists further revealed that the collision between such galaxies leads to the formation of elliptical galaxies, but said that we can expect this dance to continue throughout our lives, as galaxy collisions often take place on hundreds of millions of years.
NASA attributed the reason for their interaction to the immense gravitational pull between them, but added that such gravitational interactions are common and are an important part of galactic evolution. Previously, the Hubble Telescope had won the internet for a spectacular viewing video showing four of Saturn’s huge constellations with 82 moons parading across the face of the planet.
In the Instagram post, NASA highlighted the large orange moon Titan and Saturn’s ice Mimas on the right, and the icy moons Enceladus and Dione on the far left. He even added the song “Time Will Tell” in the background to make the message even more heartfelt and epic. The post was captioned “Celebrate #InternationalMusicDay by Exploring Sonication.” Scientists interpret the data from the images by representing them in sound, thus creating beautiful cosmic music! “
