OUR GALAXY IS RACING THROUGH THE COSMOS AT 2.1 MILLIOM KILOMETRE PER HOUR!
When we look up at the night sky, it often feels as though everything is still and timeless. But the truth is far more astonishing: our Milky Way Galaxy is hurtling through space at an unimaginable speed of about 2.1 million kilometers per hour!
Yes, you read that right. That’s nearly 600 kilometers every second.
🌌 How Do We Know This?
Astronomers measure our galaxy’s motion relative to the Cosmic Microwave Background (CMB)—the faint glow left behind from the Big Bang. Against this backdrop, the Milky Way is racing through space, pulled by the gravity of other galaxies and cosmic structures.
🚀 Putting That Speed in Perspective
A passenger jet: 900 km/h
The fastest spacecraft ever built (Parker Solar Probe): 700,000 km/h
Milky Way Galaxy: 2,100,000 km/h
In other words, our entire galaxy is moving 3 times faster than the fastest human-made spacecraft—and we don’t even feel it!
🌍 Why Don’t We Notice?
Because everything in our galaxy—the Sun, Earth, and all the stars—are moving together. It’s like being on a smooth, high-speed train: unless you look outside, you’d never realize how fast you’re going.
✨ A Cosmic Dance
The Milky Way is not traveling alone. It’s on a slow-motion collision course with our neighboring Andromeda Galaxy, and billions of years from now, the two galaxies will merge into one giant elliptical galaxy.
📌 Takeaway
The next time you gaze at the stars, remember: you are part of an incredible journey, flying through the universe at over 2 million kilometers per hour. Far from being still, our universe is in constant motion—an endless, majestic dance of galaxies.
