G49

G49 FilamentThis image shows a filament of dust and gas called G49. It contains 80,000 Suns’ worth of mass and measures about 280 light-years long by roughly 5 light-years across. It’s about 18,000 light-years away.

In this false-color image taken by the Herschel space observatory, longer-wavelength light has been assigned visible colors. Light with wavelengths of 70 µm is blue, 160 µm light is green. 350 µm light is red. The cooler gas seen in red and yellow is quite cold, as low as -252 C.
