http://www.spitzer.caltech.edu/resource_list/0-Image-Gallery http://www.spitzer.caltech.edu/images/spitzer_icon.png?1358198578 This infrared image from NASA's Spitzer Space Telescope shows the double-ringed galaxy Messier 94. Just outside the bright core, a burning ring of star formation glows brightly in the light of warm interstellar dust. Encircling it all is the faint blue glow of starlight forming what was long taken to be an outer ring of stars, but may not be a ring at all.

The discovery gives scientists a window into the earliest and least understood phases of star formation.

These surprisingly regular pulsations, recurring every 25.34 days, were discovered by NASA's Spitzer Space Telescope during a period spanning seven years of repeated observations.

Stellar winds flowing out from this fast-moving star are making ripples in the dust as it approaches, creating a bow shock seen as glowing gossamer threads, which, for this star, are only seen in infrared light.
