It’s enormous, spanning about 2 x 1.5 degrees of the sky (15 times the size of the full Moon on the sky), and is actively cranking out stars. The valentine-shape is actually an enormous cavern, a hollow carved out of the gas by the winds and fierce ultraviolet light flooding out from massive young stars in its… well, its heart. It’s like these stars are blowing a vast bubble in the middle of the cloud.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blogs.discovermagazine.com/badastronomy/2008/08/22/the-beating-heart-of-w5/"><P>The stars doing the work can be seen in the image; the bright blue ones are the culprits.
