Compass and Scale Image of SNR 0509

Compass and Scale Image of SNR 0509

Image of supernova remnant 0509-67.5, with compass arrows, scale bar, and color key for reference.

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).

The color key shows which filters from Hubble's ACS (Advanced Camera for Surveys) and WFC3 (Wide Field Camera 3) instruments were used when collecting the light.

About The Data
Data Description The optical image was created from Hubble data from proposals: : J. Hughes, J. Warren, and L. Hovey (Rutgers University), C. Badenes (Weizmann Institute of Science, Israel), C. Smith (NOAO/CTIO), J. Vink (Space Research Organization, Netherlands), and P. Ghavamian (STScI); : K. Noll, Z. Levay, M. Livio, H. Bond, C. Christian, L. Frattare, M. Mutchler, and T. Borders (Hubble Heritage Team/STScI). The X-ray data are from the CXO proposals: 776, 7635, 8554: NASA/CXC/SAO/ J.Hughes et al.
Instrument HST>ACS/WFC, HST>WFC3/UVISl, and Chandra>ACIS
Filters HST: F475W (g), F555W (V), F658N (H-alpha+[N II]), and F814W (I) CXO: 0.2-1.5 keV and 1.5-7 keV
About The Image
Color Info This image is a composite of separate exposures acquired by the WFC3 and ACS instruments on HST, and the ACIS instrument on the Chandra X-ray Observatory. Several filters were used to sample broad and narrow wavelength ranges along with X-ray energy frequencies. 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: Orange: F814W (I) Red: F658N (H-alpha+[N II]) Light green: F555W (V) Purple: F475W (g) Green: 0.2-1.5 keV Blue: 1.5-7 keV
Compass Image On a dark background—with compass arrows, scale bar, and color key for reference—a nearly-circular pink ring surrounds a translucent sphere of diffuse blue and green gas. Green gas mostly appears near the top of the ring while blue gas lines its interior. The dark background is covered with white and blue stars in various sizes, with some having diffraction spikes. Many of the background stars that are located behind the object appear tinted with blue or green.
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.
