The New Hottest Spot in the Milky Way

Two days ago, NASA's Spitzer Space Telescope revealed an image of what could be the brightest star in our galaxy: Wolf-Rayet star WR 102ka or, more fondly, the "Peony nebula" star. Astronomers say that it burns with the light intensity of 3.2 million suns — but that's a rough estimate, and one that might even stretch to 4 or 5 million suns.

Researchers at NASA and Germany's Potsdam University observed the Peony nebula star, which by the way is about 100 times wider and 200 times heavier than our familiar sun. NASA offers more images, including a zoomed-in video view, of the Peony nebula at the link below.
