🪐 In the spiral galaxy NGC 4945, located about 13 million light-years away in the constellation Centaurus, astronomers have measured jets of material shooting out from the galaxy's core at speeds approaching the speed of light—nearly 299,792 kilometers per second. This dazzling velocity, known as "relativistic speed," shows how cosmic engines powered by supermassive black holes can accelerate particles close to nature’s ultimate speed limit, producing jets that blaze across tens of thousands of light-years. ✨ #speedoflight⚡#relativistic⚡#jets⚡#NGC4945⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
