The star cluster Hodge 301 is 20 million to 25 million years old. Hodge 301 is home to many aging, red supergiant stars, indicating the cluster is older. Roughly 40 massive stars already have exploded as supernovas. The expanding wave of debris is slamming into gas ejected by stars in R136, creating a ridge of star formation between the two clusters. The fledgling stars are embedded in dense gas and cannot be seen.
30 Doradus is the brightest, nearby star-forming region and home to the most massive stars in our cosmic neighborhood of about 25 galaxies. The nebula is close enough to Earth that Hubble can resolve individual stars, giving astronomers important information about the stars' birth and evolution. 30 Doradus resides 170,000 light-years away in the Large Magellanic Cloud, a small, satellite galaxy of our Milky Way.

| Data Description | This image combines many exposures from the Hubble Space Telescope's Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) from the HST proposal : D. Lennon and E.

| About The Image | |
| Color Info | This image is a composite of many separate exposures made by the ACS and WFC3 instruments on the Hubble Space Telescope along with ESO 2.2m ground-based observations. In total, two filters were used to sample narrow wavelength emission and two filters were used to sample broadband wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Red: ESO H-alpha (656nm) Green: ESO average of H-alpha+[O III] Blue: ESO [O III] (502nm) Luminosity*: ACS/WFC F775W + WFC3/UVIS F775W * The higher-resolution, black & white Hubble image and the lower-resolution, color ESO images were combined using a technique that takes luminosity (brightness) information from the black and white ACS/WFC3 image and color information from the composite ESO image. This preserves all of the higher-resolution detail from the Hubble data while rendering a color image representing the physical processes in this active region of space. |
