Title: Distance estimation of some selected small Bok globules Author: A. Das, H. S. Das, A. S. Devi The distance determination of small Bok globules is often difficult because of its small size and opaqueness. In this work, we determine the distances to six small Bok globules CB 17, CB 24, CB 188, CB 224, CB 230 and CB 240 using near infra red photometry (2MASS JHK_S colours). The distances to these clouds are estimated to be 478±88, 293±54, 262±49, 378±70, 293±54 and 429±79 parsec respectively. Read more (3150kb, PDF) __________________

Expand (251kb, 1280 x 960) Credit NASA Thackeray Globule.kmz Google Sky file (1kb, kmz) Dark clouds in the HII star-forming region, IC 2944 Position (2000): R.A. 11h 38m 23s, Dec. -63° 20' 41.5" Constellation: Centaurus Distance: 5,900 light-years Spoiler Thackeray's Globules are dense, opaque dust clouds in outer space, known as globules, in the star-forming region IC 2944. Little is known about the origin and nature of these globules in IC 2944, which were first found by astronomer A. David Thackeray in 1950. Globules are generally associated with large hydrogen-emitting star-formation regions, which give off the glowing light of hydrogen gas. Read more __________________
