Hydrogen Plume in M82

Plumes of gas and dust amid a field of numerous faint, resolved stars blown from the central regions of M82 into the outer "suburbs."

About the colours

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using several different filters. Three filters sample broad wavelength ranges, one isolates the light of hydrogen. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F435W (B) Green: F555W (V) Red-orange: F658N (H alpha) Red: F814W (I)
