Swirling Lagoon
Seen through binoculars or small telescopes, the Lagoon nebula is a ghostly blur tinged with pink tucked inside the constellation Sagittarius. But with the powerful gaze of the Gemini South telescope in Chile, astronomers have created a dramatic new view of this stellar nursery.
Released this week, the false-color picture shows the nebula in vibrant hues thanks to a combination of data from several light filters. The dense cloud of dust and gas is a birthplace for medium- and low-mass stars, most of which are embedded in thick cocoons of material. The bluish points of light in the frame are young stars in the background.
