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.

Seen here in visible light, the North America Nebula strangely resembles its namesake continent. Expanding our view to include infrared light, the dark dust lanes and concealed stars glow in red colors while the continental gas clouds shift to an ocean-?like blue. Pushing entirely into the infrared spectrum, we see even more detail in the convoluted dust clouds.

While astronomers have identified over 500 planets around other stars, they?re all too small and distant to fill even a single pixel in our most powerful telescopes. That?s why science must rely on art to help us imagine these strange new worlds.

Today's telescopes study the sky across the electromagnetic spectrum. Each part of the spectrum tells us different things about the Universe, giving us more pieces of the cosmic jigsaw puzzle. The most powerful telescopes on the ground and in space have joined forces over the last decade in a unique observing campaign, known as the Great Observatories Origins Deep Survey, or GOODS, which reaches across the spectrum and deep back into cosmic time.
