Evidence from observations and computer simulations supports a picture of galaxy growth that isn't dominated by the rough-and-tumble crashes of big galaxies. Instead, most of the universe's stellar metropolises appear to feed themselves with nibbles instead of feasts.
Our Milky Way Galaxy is one of the most mysterious galaxies we observe. That’s because we’re studying it from inside its spiral disk, surrounded by its stars, gas, and dust. Astronomers are still piecing together a map of what our galaxy looks like, though even counting its spiral arms has been a lesson in humility. Still, the Milky Way holds plenty of secrets. We’re still trying to understand its history, and astronomers are tenaciously trying to glimpse the silhouette of its supermassive black hole. What’s more, our galaxy still surprises us with discoveries of baby stars near and far.
Here you’ll find the latest news on the bustling stellar metropolis we live in, the dwarf galaxies that make up its suburbs, and our evolving picture of everything Milky Way.
