Little Dumbbell Nebula (WFC3 Compass Image)

Annotated image labeled “Little Dumbbell Nebula, M76, HST WFC3/UVIS” against the black background of space. Near top left, a color key consisting of five lines reads: “F475W SDSS g’” in cyan; “F502N OIII” in dark blue; “F656N Ha” in green; “F658N NIII” in red; and “F814W I” in orange. The nebula is located 3,400 light-years away in the northern circumpolar constellation Perseus. The name 'Little Dumbbell' comes from its shape that is a two-lobed structure of colorful, mottled, glowing gases resembling a balloon that’s been pinched around a middle waist. Like an inflating balloon, the lobes are expanding into space from a dying star seen as a white dot in the center. Blistering ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen. At bottom left corner is a scale bar labeled “1 light-year.” At bottom right corner, the “E” compass arrow points towards the 10 o’clock position. The “N” arrow points towards the 1 o’clock position.

    DistanceThe 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.
    3,400 light-years
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Image is about 5 arcminutes across (about 5 light-years)

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

These images are a composite of separate exposures acquired by the WFC3/UVIS instrument on the Hubble Space Telescope. Several filters were used to sample various wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Cyan= F475W, Blue= F502N, Green= F656N, Red= F658N, Orange= F814W
