W5

W5 is a star forming region near Casseiopeia.

	'The Fish' is an object named for its curious morphology in molecular hydrogen as shown. The 'eye' is a young star. The border of the Fish is molecular hydrogen that has been excited and is shining in the near infrared. The striations are an instrumental effect of the narrow-band filters on NICFPS, the instrument used to take this data
	This isophotal surface plot is of IC 1396 and SH 2-201, pieces of the western part of W5. It resembles a dragon and, in this orientation, vaguely resembles the Welsh Flag. Around the office, we refer to it as the Welsh Flag Nebula. The data was taken using the HARP-B instrument on the James Clerk Maxwell Telescope. It is carbon monoxide (CO) emission measured at submillimeter (~850 micron) wavelengths. The 3D structure is from the velocity of the gas, which is moving at a few kilometers per second (not very fast in astronomical terms.)
