These two images, taken in visible and infrared light by the Wide Field Camera 3 aboard NASA's Hubble Space Telescope, reveal a massive star cluster nestled in the largest stellar nursery in our local galactic neighborhood.
The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. The nebula is close enough to Earth that Hubble can resolve individual stars, giving astronomers important information about the stars' birth and evolution.
In the image at left, taken in ultraviolet, visible, and red light, the stars look like icy blue diamonds. The green in the nebula is from the glow of oxygen and the red is from fluorescing hydrogen.
In the image at right, taken at infrared wavelengths, Hubble sees through the dusty nebula, revealing many stars that cannot be seen in the visible-light view. The large bright star just above the center of the image is in 30 Doradus. The observation was taken through two infrared filters (1.1 microns and 1.6 microns).
The Hubble observations of 30 Doradus were made Oct. 20-27, 2009.

| About The Image | |
| Color Info | The images are composites of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Five filters were used to sample broad and narrow wavelength ranges for the UVIS image. Two filters were used to sample broad wavelength ranges from the IR image. The colors result from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: WFC3/UVIS Image Blue: F336W (U) and F438W (B) Green: F555W (V) Red: F814W (I) Orange/red: F656N (H-alpha) WFC3/IR Image Cyan: F110W (J) Orange: F160W (H) |

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
