🪐 In the galaxy Messier 87, located about 55 million light-years from Earth, the speed of light helps astronomers study powerful jets that erupt from its supermassive black hole. Light from these jets takes millions of years to cross the vast gulf to Earth, allowing scientists to observe how particles accelerated close to light speed behave over incredible distances and time, giving a glimpse into the dynamics of some of the universe’s most energetic events. ✨ #speedoflight⚡#messier87⚡#blackhole⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 In the Virgo constellation, astronomers study galaxy clusters like Virgo Cluster to understand the universe’s endgame, using real data to measure how the mysterious force called dark energy is speeding up cosmic expansion. If this expansion keeps accelerating, even giant galaxies such as Messier 87 will someday drift so far apart that their light can no longer reach each other, resulting in a cold, ever-darkening universe filled with isolated islands of stars. ✨ #VirgoCluster⚡#darkenergy⚡#Messier87⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
