The Galactic Center Revisited (Gallery Explorer)
Hiding behind the constellations Sagittarius and Scorpius is the center of our own Milky Way galaxy, over 25,000 light years away. This patch of sky is mostly dark in visible light, shrouded by dust clouds that lie between us and the Galactic center. But the infrared vision of NASA’s Spitzer Space Telescope sees through the dust showing us this strange and tumultuous region.
