Uranus and Moons Compass Image

At top, left corner appears “Uranus – 26 July 2026.”
“HST ACS” appears on next line.
On third line, in deep blue, appears “F750N.”
On fourth line, in bright green, appears “F770N”
On fifth line, in red, appears “F790N.”
At bottom left corner is scale bar. On top of bar is “20,000 miles.” Below bar is “32,000 kilometers.” At bottom right corner, north and east compass arrows point up and left, respectively.
Four small, white dots appear in a jagged, roughly diagonal line from top right to bottom left. They are on a solid black background. A fifth white dot is superimposed on a much larger blue sphere with pink, white, and lighter blue diagonal striations, also on the black background. Also superimposed on the sphere is a tiny black dot, to the right and slightly beneath the white dot. Encircling the blue sphere at the same steep diagonal angle as the white dots and striations are thin, ghostly, white, Saturn-like rings. The four white dots are labeled, from top right to bottom left, “Titania,” “Oberon,” “Umbriel,” and “Miranda.” The white dot and its accompanying black dot are labeled “Ariel and shadow.” The faint rings encircling the blue sphere are labeled simply “rings.”
About This Image
Caption
This image of Uranus and its five classical moons -- Titania, Oberon, Umbriel, Miranda and Ariel -- was captured by the Hubble Space Telescope’s Advanced Camera for Surveys (ACS).
The image shows a scale bar, compass arrows, and color key for reference.
The scale bar is labeled in miles along the top and kilometers along the bottom.
The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).
This image shows visible wavelengths of light that have been translated into visible-light colors. The color key shows which ACS filters were used when collecting the light. The color of each filter name is the visible-light color used to represent the light that passes through that filter.
