描述The date: September 30, 1880 The place: A private observatory in Hastings-on-Hudson Profession of the observer: A medical doctor The instrument: An l1-inch Clark refractor. The significance of that night marked one of the truly great turning points in the development of astronomical techniques: Dr Henry Draper, a wealthy New York medical doctor, had secured the first photograph of a nebula: a 51-minute exposure on a dry gelatinobromide plate showing the wispy nebulosity of the Orion Nebula. By March 1882, Draper had secured an exposure of 137 minutes, showing far richer detail of both bright and dark features. The rest is histapy. The photographic era heralded in a universe where hints of the presence of cosmic dust were strongly alluded to: from star-forming regions such as Messier 17, to the Horsehead Nebula in Orion, to the striking dark finger in the Cone Nebula, to the magnificent dark bands in the plane of our Milky Way. "Historically, astromomers from the very beginning have been afraid of dust.

Optical, IR, and HI Observations of a Large Complete Cluster Sampleecified selection criteria within the volume of the cluster can be included. For example, a flux threshold might be set in some spectral band and this threshold corresponds to a specific . threshold for a complete sample.

Organics and Ices in Galactic Dust. Laboratory organics produced by different processes are compared to the DISM features. The 3.4 .m feature has now been detected in other galaxies, which suggests that the widespread distribution of organic material in our own galaxy may be common to other galaxies as well.

Temperature Fluctuations and Very Cold Dust the average temperature between high temperature spikes and will spend the majority of the time at these low temperatures. As a result, they will contribute excess emission at very . infrared wavelengths and this emission will be seen in IRAS sources at . wavelengths.

The Effects of Supergiants on the Infrared Light Distribution in Galaxiesue to giant stars, ~ 7% due to main sequence stars, and only ~ 1% due to supergiants. Since main sequence stars, which dominate the mass, and giants are well–mixed in older populations (see Aaronson 1977 and Frogel 1988), K images should trace the mass effectively.
