A spectacular Hubble Space Telescope image reveals the heart of the Lagoon Nebula. Seen as a massive cloud of glowing dust and gas, bombarded by the energetic radiation of new stars, this placid name hides a dramatic reality. The Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope has captured a dramatic view of gas and dust sculpted by intense radiation from hot young stars deep in the heart of the Lagoon Nebula (Messier 8).
Thackary's Globules. Located in rich star fields & hydrogen gas, these opaque clouds of interstellar dust & gas are so large they might be able to form stars. They are located in IC 2944, a bright stellar nursery about 5900 ly away toward the constellation Centaurus. The largest of these dark globules, first spotted by S African astronomer A. D. Thackeray in 1950, is likely two separate but overlapping clouds.
