The Hubble Space Telescope captured the iridescent
tapestry of star birth in a neighbouring galaxy in this panoramic view of
glowing gas, dark dust clouds, and young, hot stars. The star-forming region,
catalogued as N11B lies in the Large Magellanic Cloud (LMC), located only
160,000 light-years from Earth. With its high resolution, the Hubble Space
Telescope is able to view details of star formation in the LMC as easily as
ground-based telescopes are able to observe stellar formation within our own
Milky Way galaxy.
Our neighbourhood galaxy the Large Magellanic Cloud
(LMC) lies in the Constellation of Dorado and is sprinkled with a number of
regions harbouring recent and ongoing star formation. One of these star-forming
regions, N11B, is shown in this Hubble image. It is a subregion within a larger
area of star formation called N11. N11 is the second largest star-forming region
in LMC. It is only surpassed in the size and activity by "the king of stellar
nurseries," 30 Doradus, located at the opposite side of LMC.
The image
illustrates a perfect case of so-called sequential star formation in a nearby galaxy -- new
starbirth triggered by old massive stars. The sequence begins with a cluster
of stars outside the top of the Hubble image which led to the birth
of the collection of blue- and white-coloured stars near the left of this new Hubble
image.
These stars are among the most massive stars known
anywhere in the Universe. The region around the hot stars is relatively clear of
gas, because the stellar winds and radiation from the stars have pushed the gas
away. When this gas collides with surrounding material, it is compressed and can
collapse under its own gravity and start to form new stars. This chain of
consecutive star birth episodes has been seen in more distant galaxies, but it
is shown very clearly in this Hubble image.
