Horsehead nebula (Barnard 33). Infrared image of the Horsehead nebula (upper right), which is located around 1500 light years from Earth in the constellation Orion. The horsehead shape, which is several light years across, is formed by an intrusion of dust into the emission nebula IC 434. Its red glow is due to the ionisation of hydrogen by radiation from nearby stars. At lower right is the reflection nebula NGC 2023. Reflection nebulae reflect the light of bright stars within or near them. They typically appear blue as blue light is scattered more effectively than red. Image taken by VISTA (the Visible and Infrared Survey Telescope for Astronomy), the worldâs largest survey telescope, located at ESO's Paranal Observatory in Chile.
