NGC 6559 and IC 1274-75
Date created: 1979-08-14
Tags: nebula, dust, AAT, emission, reflection
This dusty region in Sagittarius
is probably associated with the brighter and better-known Lagoon
and Trifid Nebulae
which are nearby in the sky and part of the same molecular cloud. The soft red glow of fluorescent hydrogen is evidence that there are young hot stars associated with the dusty clouds. These bright stars also illuminate the tiny solid particles, producing blue reflection nebulae bordering some of the emission regions. The dust is also evident in silhouette, both as sinuous dark lanes winding through the luminous gas and as the dark patches obscuring the ancient, yellow stars that populate the central parts of the Milky Way. Photograph made from plates taken in April 1979 (R), June 1979 (B) and July 1979 (G).
Image width is about 47 arcmin.
