The Trifid Nebula,
also known as Messier 20, is easy to find with a small telescope. About 30
light-years across and 5,500 light-years distant it’s a popular stop for cosmic
tourists in the nebula rich constellation Sagittarius. As
its name suggests, visible light pictures
show the nebula divided into three parts by dark, obscuring dust lanes. But this penetrating
infrared image reveals the Trifid’s filaments of glowing dust
clouds and newborn stars. The spectacular false-color view is courtesy of the Spitzer Space Telescope.
Astronomers have used the infrared image data
to count newborn and embryonic stars
which otherwise can lie hidden in the natal dust and gas clouds of this
intriguing stellar nursery.
Launched in 2003, Spitzer explored the infrared Universe from an Earth-trailing
solar orbit until its science operations were brought to a close earlier this
year, on January 30.
