#emission nebula
An enhanced Scorpius constellation!! If it looked this good to the unaided eye, we might might remember it better, typically appears as a few bright stars in a constellation. To get a spectacular image like this, though, you’d need a good camera, a dark sky, and some sophisticated image processing. The resulting digitally-enhanced image shows many breathtaking features. Diagonal across the right side of the image is part of the Milky Way Galaxy. Visible there are vast clouds of bright stars and long filaments of dust. Rising vertically on the left are dark dust bands known as the Dark River. Several of the bright stars on the left are part of Scorpius’ head and claws, and include the bright star Antares. Numerous red emission nebulas, blue reflection nebulas, and dark filaments are visible as well. Scorpius appears prominently in southern skies after sunset during the middle of the year.

NGC 3572 and the Southern Tadpoles
This cosmic skyscape features glowing gas and dark dust clouds along side the young stars of NGC 3572. A beautiful emission nebula and star cluster in far southern skies, the region is often overlooked by astroimagers in favor of its brighter neighbor, the nearby Carina Nebula. Stars from NGC 3572 are toward the upper left in the telescopic frame that would measure about 100 light-years across at the cluster’s estimated distant of 9,000 light-years. The visible interstellar gas and dust is part of the star cluster’s natal molecular cloud. Dense streamers of material within the nebula, eroded by stellar winds and radiation, clearly trail away from the energetic young stars. They are likely sites of ongoing star formation with shapes reminiscent of the cosmic Tadpoles of IC 410 better known to northern skygazers. In the coming tens to hundreds of millions of years, gas and stars in the cluster will be dispersed though, by gravitational tides and by violent supernova explosions that end the short lives of the massive cluster stars.
