🪐 In 2019, astronomers detected gravitational waves from the collision of two white dwarf stars in the galaxy NGC 4993. White dwarfs are the dense, burned-out cores of stars like our Sun, and when they merge, the resulting ripples in space—gravitational waves—allow scientists to study these rare cosmic smashups in entirely new ways beyond traditional light-based astronomy. ✨ #gravitationalwaves⚡#NGC4993⚡#whitedwarfs⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
