These Hubble Space Telescope images show striking differences between the visible-light and near-infrared-light views of a star-making pillar of gas and dust, called the Horsehead Nebula. The nebula appears as a solid dark structure in the visible-light image at top. The bright area at the top left edge is a young star still buried in its nursery of gas and dust. The entire top of the nebula is being sculpted by radiation from a massive star located out of Hubble's view.
In the near-infrared image at bottom, the Horsehead appears more transparent because infrared light penetrates gas and dust to reveal details not seen in the visible-light view. The star that was buried in gas and dust in Hubble's visible-light image glows brightly in the near-infrared view. A rich tapestry of Milky Way stars and distant galaxies also appear in the infrared image.
