An active stellar nursery
glows with a deep reddish hue in this image of NGC 2467, a booming complex of
star formation in the southern constellation of Puppis.
Observed by the Gemini
South telescope at Cerro Pachón in Chile, the NGC 2467 complex sits about 17,000
light-years away. One light-year, the distance light travels in a single year,
is about 5.8 trillion miles (9.4 trillion kilometers).
The image displays a
striking array of features that illustrate multiple phases of star birth,
including a cluster of young stars dominates the left edge of the field of
view. In the lower right, young stars are emitting hot radiation, exciting the
nearby gas and causing it to glow, which reveals even denser gas and dust
clouds. Dust lanes and dark globules mark sites of future star
formation.
Astronomers say
it's likely that several million years ago this region resembled the
currently active star birth regions seen in the right half of the
image. The “wall” of denser material that dominates the right side of the
image shows ultraviolet radiation from nearby stars removing material
-through 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.
This image was obtained on
December 5, 2004 using the Gemini Multi-Object Spectrograph (GMOS) instrument on
Gemini South. It was released this week at the American Astronomical Society in
San Diego, California as the first of a completely new gallery of Gemini
Observatory images.
