This web site contains information on the use of different wavelength filters to determine astronomical information by the Hubbble Space Telescope. The use of color to enhance black and white images is included. The site also contains several series of images at different wavelengths to illustrate the presentation.

| Title | ComPADRE: Resources for Physics and Astronomy Education |
|---|
| Link | http://www.compadre.org/ |

| Description | ComPADRE is a set of communities of teachers and students in physics and astronomy and web-based collections of resources to support their needs. The communities supported by ComPADRE are groups that can benefit from the sharing of materials, information, and experiences in a web environment. Example communities include teachers of specific physics or astronomy courses, societies of undergraduate physics and astronomy students, and teachers addressing specific grade levels, such as high-school or middle-school teachers. Resources included in the collections are chosen to enhance the teaching and learning experience, and include multimedia learning objects, lesson plans, tutorials, laboratories and other student activities, and discussion forums on the use of these materials. The different collections are organized under the ComPADRE umbrella, which provides a central database (the Physical Sciences Resource Center), technical support, support for collection editors and community leaders, and the means to coordinate efforts across the communities. |

Click on the circle to see colorized versions of the black-and-white images. Taking color pictures with the Hubble Space Telescope is much more complex than taking color pictures with a traditional camera. For one thing, Hubble doesn't use color film � in fact, it doesn't use film at all. Rather, its cameras record light from the universe with special electronic detectors. These detectors produce images of the cosmos not in color, but in shades of black and white. Finished color images are actually combinations of two or more black-and-white exposures to which color has been added during image processing. The colors in Hubble images, which are assigned for various reasons, aren't always what we'd see if we were able to visit the imaged objects in a spacecraft. We often use color as a tool, whether it is to enhance an object's detail or to visualize what ordinarily could never be seen by the human eye. next >> search | site map | mobile | about us | contact us | copyright
