To celebrate its 22nd anniversary in
orbit, the Hubble Space Telescope released a dramatic new image of the
star-forming region 30 Doradus, also known as the Tarantula Nebula because its
glowing filaments resemble spider legs. A new image from all three of NASA's
Great Observatories--Chandra, Hubble, and Spitzer--has also been created to
mark the event.
The nebula is located in the neighboring
galaxy called the Large Magellanic Cloud, and is one of the largest
star-forming regions located close to the Milky Way. At the center of 30
Doradus, thousands of massive stars are blowing off material and producing
intense radiation along with powerful winds. The Chandra X-ray Observatory
detects gas that has been heated to millions of degrees by these stellar winds
and also by supernova explosions. These X-rays, colored blue in this composite image,
come from shock fronts--similar to sonic booms--formed by this high-energy
stellar activity.
The Hubble data in the composite image,
colored green, reveals the light from these massive stars along with different
stages of star birth, including embryonic stars a few thousand years old still
wrapped in cocoons of dark gas. Infrared emission data from Spitzer, seen in
red, shows cooler gas and dust that have giant bubbles carved into them. These
bubbles are sculpted by the same searing radiation and strong winds that comes
from the massive stars at the center of 30 Doradus.
