South Galactic Pole

Type of Object:  Sources of radio emission on large scales, like the Orion nebula, or galactic center, is not observed at the galactic south pole.  Instead  the galactic south pole is a view out of our galaxy.  We find galactic cirrus - low density interstellar gas and dust seen above and below the galactic plane, as well as numerous galaxies.

Distance: 26,000 light years

Coordinates (Epoch J2000):
         Right Ascension:       
00 53 00
         Declination:                  -26 33 00.0

Radio Brightness at 1420 MHz (21 cm): Less than 1 Jy

Location on the sky: The galactic south pole is located in the constellation Sculptor.

Images shown below, at different wavelengths, cover a
1.0 degree x 1.0 degree area of the sky centered on the nebula.  The images are taken from the SKYVIEW Virtual Observatory maintained under NASA ADP Grant NAS5-32068 with P.I.
Thomas A. McGlynn under the auspices of the High Energy Astrophysics Science  Archive Research Center (HEASARC) at the GSFC Laboratory for High Energy Astrophysics. SKYVIEW contains catalogs and surveys from x-ray to radio observations. The site is located at http://skyview.gsfc.nasa.gov/

Visible image from the digitized Palomar Sky Survey E plates.  The galactic north pole is primarily a window out of the galaxy.  Note the edge of a globular cluster at the top of the image.

Far-Infrared falso-color image at 100 microns taken by the Infrared Astronomical Satellite (IRAS) Survey. Shows little dust towards the galactic south pole. A few bright dust features are seen.

False-color image taken at the radio emission of neutral hydrogen at 1420 MHz by the NRAO VLA Sky Survey.  Shows little gas towards the galactic south pole.

False-color image taken at the radio emission frequency of 4850 MHz.  Image shows the gas component..  Image is from a Green Bank survey from 0 to +75 declination).
