Terzan 5 (Webb and Hubble Compass Image)

This image of bulge fossil fragment Terzan 5 was captured by the James Webb and Hubble space telescopes. Webb’s data are from its NIRCam (Near-Infrared Camera) and Hubble’s from its Advanced Camera for Surveys (ACS).

The image shows a scale bar, compass arrows, and color key for reference.

The scale bar is labeled in light-years along the bottom, which is the distance that light travels in one Earth-year. (It takes two years for light to travel a distance equal to the length of the scale bar.) One light-year is equal to about 5.88 trillion miles or 9.46 trillion kilometers.

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 and near-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam and ACS filters were used when collecting the light. The color of each filter name is the visible-light color used to represent the infrared light that passes through that filter.
