This compass image of Hubble and Chandra data shows two elliptical galaxies, NGC 6098 at upper right and NGC 6099 at lower left. The fuzzy purple blob at bottom center depicts X-ray emission from a compact star cluster. The X-rays are produced by an intermediate-mass black hole tearing apart a star. Wavelength information at the top left corner shows the components of the image. A scale bar appears at the bottom left corner and compass directional arrows at bottom right orient the viewer.

About the Object R.A. Position Right ascension – analogous to longitude – is one component of an object’s position. R.A. Position 16:16:43

Dec. Position Declination – analogous to latitude – is one component of an object’s position. Dec. Position +19:23:28

Constellation One of 88 recognized regions of the celestial sphere in which the object appears. Constellation Hercules

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. Distance 453 million light-years

Dimensions The physical size of the object or the apparent angle it subtends on the sky. Dimensions Image is about 1.5 arcmin across (about 200,000 light-years)
