About This Video
NGC 2207 is a pair of colliding spiral galaxies. Their bright nuclei resemble a striking set of eyes. Though individual stars are too far apart to collide, the material between the stars merges to create high-density pockets of gas. These regions gravitationally collapse, triggering a firestorm of star birth. The galaxy collision will go on for several millions of years, leaving the galaxies’ shapes completely altered.
Optical: Hubble data shows trails of stars and gas trace out spiral arms, stretched by the tidal pull between the galaxies.
Infrared: Spitzer data reveals the glow of warm dust; raw material for the creation of new stars and planets.
X-ray: Chandra view reveals areas of active star formation and the birth of super star clusters.
ABOUT THE INFRARED UNIVERSE COLLECTION
The human eye can only see visible light, but objects give off a variety of wavelengths of light. To see an object as it truly exists, we would ideally look at its appearance through the full range of the electromagnetic spectrum. Telescopes show us objects as they appear emitting different energies of light, with each wavelength conveying unique information about the object. The Webb Space Telescope will study infrared light from celestial objects with much greater clarity and sensitivity than ever before. Explore the Infrared Universe.
