Grand-design spirals have well-defined arms
WebAn observational study of large-scale star formation processes in spiral galaxies with well-defined arm systems is presented. Combining new data on the current massive star formation (from H-alpha imaging) and on the total gas distribution (both atomic and molecular hydrogen, from H I and CO observations), the star formation efficiencies in- … WebJan 13, 2011 · Messier 81 (bottom of image) is a prototypical grand design spiral galaxy with its pronounced and well-defined arms spiraling into its core. At the wavelengths WISE sees, these beautiful arms show areas of compressed interstellar gas and dust, which go hand-in-hand with areas of increased star formation.
