The Milky Way is the galaxy we call home—a massive, spinning collection of stars, planets, gas, and dust stretching over 100,000 light-years across. Imagine a city of stars, with our Sun just one of over 100 billion stars in the galaxy! Its spiral arms, glowing with starlight, sweep outward like cosmic pinwheels.
At the center lies a mysterious supermassive black hole called Sagittarius A*, which quietly holds the galaxy together with its enormous gravity. The Milky Way isn’t alone—it’s part of a cosmic neighborhood called the Local Group, which includes the Andromeda Galaxy and dozens of smaller galaxies.
Every night, when you look up at the faint, milky band of light stretching across the sky, you’re peering into the dense heart of our galaxy, seeing billions of stars in one breathtaking glimpse. In a way, looking at the Milky Way is like seeing the story of the universe written in stars.
