Mendler is following a path to fame the channel has mapped over the past three years as it has launched serial stars into orbit: the supernova Miley Cyrus in 2006, Selena Gomez in 2007, the Jonas Brothers in 2008 and Demi Lovato this year. (See pictures of Disney stars throughout the years...
...trickiness of light: "Kepler's supernova is 13,000 light-years away and is the most recently observed supernova in our galaxy. At the time, Kepler's supernova shone almost as brightly as Venus for several weeks. The bright light that those first observers recorded had traveled for 13,000 years to reach them. The light from Venus, however, takes only a few minutes to reach us. We look out into the night sky and record an impression of what is out there and we are inclined to think that that is how it is now, at this moment...
...Nirvana: "Smells like Teen Spirit," 1991 "It's the Song that Broke Punk, the very incantation about self-despising entertainment that turned a dead-end Aberdeen kid into a supernova, the very last rock song everyone could rally around. (Check out the video of its first public performance on the With the Lights Out DVD; as soon as the drums kick in, the whole room learns how to levitate.) But the closer you listen, the more it sounds like straight pop. That four-power-chord sequence that never ever changes? It's got the rhythm from Boston's "More Than...
...cosmos. The dispatch may move at the speed of light, but the journey can still take hours, years, epochs--turning current events into history long before we ever learn of them. Signals from the Cassini spacecraft, currently studying Saturn's moons, take 84 min. to reach us; the supernova whose cataclysmic birth astronomers observed earlier this year was already fading millions of years...
...have made everything we know on Earth—including us—and could provide clues to the ultimate fate of the universe. And last week, a team led by Harvard astronomers announced they had seen such shrapnel. What the team observed was a stellar explosion, called a supernova, that was caused by the merger and collision of two white dwarf stars—the shriveled-up remnants of burnt-out stars. Typically, these gigantic explosions are thought to involve only one white dwarf, and astronomers have inferred from previous studies of white dwarf supernovae that the rate...
