WISE Eyes Evolution of Massive Stars

In the Perseus spiral arm of the Milky Way Galaxy, opposite the galactic centre, lies the nebula SH 2-235. As seen in visible light, SH 2-235 appears to be a small amber-coloured dust cloud that spans about a tenth the size of the full Moon. In infrared light, NASAs Wide-field Infrared Survey Explorer, or WISE, reveals SH 2-235 to be a huge star formation complex more than 100 light-years across -- as seen in this new view. This image covers an area of the sky nearly five times as high and wide as the full moon (2.44 by 2.44 degrees).
