About
New images of huge filamentary structures of gas and dust from ESA's Herschel space observatory reveal how matter is distributed across our Milky Way galaxy. Long and flimsy threads emerge from a twisted mix of material, taking on complex shapes. This image shows a filament called G49, which contains 80,000 suns' worth of mass. This huge but slender structure of gas and dust extends about 280 light-years in length, while its diameter is only about 5 light-years across. In this image, longer-wavelength light has been assigned visible colors. Light with wavelengths of 70 microns is blue; 160-micron light is green; and 350-micron light is red. Cooler gas and dust are seen in red and yellow, wit — NASA JPL · 2015. ABD devlet eseri: kamu mali, ticari islerde de serbestce kullanilabilir.
