Area surrounding the stellar cluster NGC 2467, located in the southern constellation of Puppis. With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas. The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region — the lower eye of the Mandrill), as well as vast areas of ionised gas. The bright star at the centre of the largest pink region on the bottom of the image is HD 64315, a massive young star that is helping shaping the structure of the whole nebular region.

A colourful star-forming region is featured in this stunning new NASA/ESA Hubble Space Telescope image of NGC 2467. Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars.

Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas — mostly hydrogen — that serves as an incubator for new stars.

An extremely active stellar nursery glows in deep reddish tones in this Gemini view of NGC2467 in the southern constellation of Puppis. The image displays a striking array of features that illustrate multiple phases of star birth. In the lower right, young stars are emitting hot radiation, exciting the nearby gas and causing it to glow and revealing denser gas and dust clouds. Dust lanes and dark globules mark sites of future star formation.

A cluster of young stars dominates the left edge of the field of view. It is likely that several million years ago this region resembled the currently active star birth regions seen in the right half of the image. A “wall” of denser material dominates the right side of the image. Here ultraviolet radiation from nearby stars is removing material by a process called photo-evaporation and revealing underlying dense clouds that likely harbor forming stars.

At bottom left a star can be seen exciting the cocoon of gas and dust from which it likely emerged.

The NGC2467 complex lies about 17,000 light-years away. Its distance has been calculated based upon a likely association with a nearby cluster (Haffner 19, not within image).
