North 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 north pole. Instead the galactic north pole is a view out of our galaxy. The Coma Galaxy Cluster is located near the galactic north pole. We also find galactic cirrus - low density interstellar gas and dust seen above and below the galactic plane.

Distance: 26,000 light years

Coordinates (Epoch J2000):
Right Ascension: 12 51 24
Declination: +27 07 00.0

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

	Location on the sky: The galactic north pole is located in the constellation Coma Berenices.

	Visible image from the digitized Palomar Sky Survey E plates. The galactic north pole is primarily a window out of the galaxy.


	Far-Infrared falso-color image at 100 microns taken by the Infrared Astronomical Satellite (IRAS) Survey. Shows little dust towards the galactic north pole

	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 north pole.
