Explanation: In one of the brightest parts of Milky Way lies a nebula where some of the oddest things occur. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebula. Eta Carinae, the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically. The Keyhole Nebula, visible left the center, houses several of the most massive stars known and has also changed its appearance. The entire Carina Nebula spans over 300 light years and lies about 7,500 light-years away in the constellation of Carina. Pictured above is the most detailed image of the Carina Nebula ever taken. The controlled color image is a composite of 48 high-resolution frames taken by the Hubble Space Telescope and released to honor its 17th anniversary. Wide-field annotated and zoomable image versions are also available.

It is believed there may be another person still in the debris, journalist Andrew Finkel told CNN, and rescue crews were listening and digging. No deaths have been reported.

MIT admissions dean resigns

With colleges demanding kids who play sports, run student government and take the heaviest course load they can, Jones shouted back the opposite: daydream, stay healthy, and don't worry so much about building a resume just to impress an elite college.
