These two close-up images by the Hubble Space Telescope reveal how different the star-forming nebula NGC 2174 appears in visible and near-infrared light. On the left is a visible-light view, revealing a rugged landscape, with ridges and tall
pillars of gas.
The near-infrared image, at right, shows how infrared light penetrates more dust and gas than visible light, revealing details within the nebula.
Background stars and several galaxies appear in the infrared view.
