ABOUT
THIS IMAGE:
A colorful
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 colorful background of glowing gas in this newly released Hubble
image. The star-forming region NGC 2467 is a vast cloud of gas - mostly
hydrogen - that serves as an incubator for new stars. Some of these youthful
stars have emerged from the dense clouds where they were born and now
shine brightly, hot and blue in this picture, but many others remain hidden.
The full beauty of this object and hints of the astrophysical processes
at work within it are revealed in this super-sharp image from Hubble.
Hot young stars that recently formed from the cloud are emitting fierce
ultraviolet radiation that is causing the whole scene to glow while also
sculpting the environment and gradually eroding the gas clouds. Studies
have shown that most of the radiation comes from the single hot and brilliant
massive star just above the center of the image. Its fierce radiation
has cleared the surrounding region and some of the next generation of
stars are forming in the denser regions around the edge.
One of the most familiar star-forming regions is the Orion Nebula, which
can be seen with the naked eye. NGC 2467 is a similar but more distant
example. Such stellar nurseries can be seen out to considerable distances
in the Universe, and their study is important in determining the distance
and chemical composition of other galaxies. Some galaxies contain huge
star-forming regions, which may contain tens of thousands of stars. Another
dramatic example is the 30 Doradus region in the Large Magellanic Cloud.
NGC 2467 was discovered in the nineteenth century and lies in the southern
constellation of Puppis, which represents the poop deck of Jason's fabled
ship Argo from Greek mythology. NGC 2467 is thought to lie about 13 000
light-years from Earth.
The picture was created from images taken with the Wide Field Channel
of the Advanced Camera for Surveys through three different filters (F550M,
F660N and F658N, shown in blue, green and red respectively). These data
were taken in 2004.
