🪐 In the Perseus Cluster, a supermassive black hole at the center of the galaxy NGC 1275 sends out powerful sound waves that ripple through the surrounding gas. These cosmic vibrations have wavelengths so vast—spanning around 30,000 light-years—that they produce the deepest note ever detected, 57 octaves below middle C, making it a real, albeit inaudible, “song” of the universe. ✨ #PerseusCluster⚡#blackhole⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the Perseus Galaxy Cluster, astronomers have found that its galaxies move in ways that visible matter alone can't explain—pointing to huge amounts of dark matter, an invisible form of matter detected only by its gravity. Surprisingly, dark energy—an even more mysterious force—is also at work here, pushing galaxies apart and accelerating the universe’s expansion, making Perseus a real example of how both dark matter and dark energy shape the cosmos while remaining hidden from our eyes. ✨ #PerseusCluster⚡#darkmatter⚡#darkenergy⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
