This portion of the Hubble GOODS-South field contains hundreds of visible galaxies. A representative sample of those galaxies on the right half of the image also have their spectra overlayed in a representation of slitless spectroscopy.

Summary

[edit]
Description
English: This portion of the Hubble GOODS-South field contains hundreds of visible galaxies. A representative sample of those galaxies on the right half of the image also have their spectra overlayed in a representation of slitless spectroscopy. By using slitless spectroscopy, a spectrum is obtained that contains both spatial and wavelength information. For example, the inset highlights a spiral galaxy that shines brightly in the emission line of hydrogen-alpha (Hα) as well as in broad starlight (the horizontal strip of light). Its spiral shape is traced by the Hα portion of the spectrum. By combining imaging and spectroscopy, astronomers can learn much more than from each technique alone.
