1.   Dr. Lanzetta and his colleagues analyzed with different filters the color of infrared light from the faint galaxies in the most distant images taken by the Hubble telescope.

2.   The CCDs are arranged in five rows, each of which is equipped with a different colored filter.

3.   The Keck is observing impact sites using seven different colored filters, each one corresponding to the kind of light emitted by different compounds.

4.   To avoid such monochromaticity, astronomers took separate pictures of the Eagle through different filters.

5.   Different filters likely will be needed for searching for different evidence, he said.

6.   Each will be taken with a different filter and they will be combined to produce full-color images.
