from the poster paper (45.13) ``Neutral Gas Associated with the Pleiades Reflection Nebula'', Bull. A.A.S., 27, 1349

featured in the January 17th Wisconsin State Journal and the June issue of Astronomy magazine

Intricately structured filaments of gas and dust compose the reflection nebula seen around the Pleiades star cluster. These multiwavelength images were presented to the American Astronomical Society meeting in San Antonio, TX on January 16, 1996. Click here for the press release text.

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.
