This visualization explores the Orion Nebula using both visible and infrared light. The sequence begins with a widefield view of the sky showing the plane of our Milky Way Galaxy, then zooms down to the scale of the Orion Nebula. The visible light observation (from the Hubble Space Telescope) and the infrared light observation (from the Spitzer Space Telescope) are compared first in twodimensional images, and then in threedimensional models.

As the camera flies into the starforming region, the sequence crossfades back and forth between the visible and infrared views. The glowing gaseous landscape has been illuminated and carved by the high energy radiation and strong stellar winds from the massive hot stars in the central cluster. The infrared observations generally show cooler temperature gas at a deeper layer of the nebula that extends well beyond the visible image. In addition, the infrared showcases many faint stars that shine primarily at longer wavelengths. The higher resolution visible observations show finer details including the wispy bow shocks and tadpoleshaped proplyds. In this manner, the movie illustrates the contrasting features uncovered by multiwavelength astronomy.
