| Pleiades Optical Reflection Nebulosity |
|
Faint reflection nebulosity -- starlight shining off grains of
interstellar dust -- extends far from the `Seven Sisters' in the center of the
cluster. This mosaic of 40 visible-light images was taken with the 0.6-meter
(24-inch) Burrell Schmidt telescope at Kitt Peak National Observatory, near
Tucson, Arizona.
[The Schmidt data were processed further after this photo release; better versions are now available.]

| Pleiades Far-Infrared Heated Dust Emission |
| Glowing filaments seen in the far-infrared are the result of dust particles, heated by the Pleiades stars, re-radiating their energy into space. This image is from data taken by the Infra-Red Astronomical Satellite (IRAS) in the 1980s. |

| Pleiades Hydrogen Gas Nebular Filaments |
| Numerous wisps and streamers of atomic Hydrogen gas are found near the Pleiades and appear to be closely associated with dust filaments seen at optical and infrared wavelengths. This composite image of large-scale and fine-scale structure was made from 21-cm wavelength radio telescope observations, using the Green Bank 140-ft. telescope in West Virginia and the Very Large Array telescope in New Mexico. |
