Thanks to the distortion-reducing power of the ALTAIR adaptive optics system on the Gemini North telescope in Hawaii, three University of Toronto scientists were able to capture images of the star 1RXS J160929.1-210524 from a distance of about 500 light years away. The image is believed to be the first ever of a planet in an alien solar system around a sun-like star. The discovery is made even more significant because the "planet" lies a tremendous distance away from its parent star—challenging currently accepted theories about star and planet formation. It will take up to 2 years of research to determine whether or not this object is, in fact, tied to the star by gravity. [Gemini via ScienceNews via DVICE]

Mars Phoenix Will Bravely and Passionately Twitter Until the Final Beat of Its Adorable Electronic Heart [Goodnight Sweet Rover]

The Mars Phoenix Lander has been Twittering away its mission details since landing on Mars in May. But lately, you can see a sense of impending doom starting to creep in, slowly: "It's noon, Sol 81. I've spotted frost around my landing site in AM," tweeted Phoenix a few weeks ago. "Seasons are longer here...I'll be surrounded by ice & don't expect to survive til Spring," comes a few days later. But unlike other eerie autobiographical accounts of impending death, the wildly successful Mars Phoenix Lander has a trick up its sleeve for a potential reincarnation after the thaw.
"But as I've said before, I'm programmed with a 'Lazarus mode' so I'll call up to the Mars orbiters if I re-awaken in the Spring," said Phoenix last week, probably in response to tearful return Tweets lamenting his/her/its grim disposition. If its solar panels collect enough juice come springtime, the first auto-function will be to contact the Mars Orbiter above with the good news of its reincarnation.
The folks at NASA are proud to be operating Phoenix at all at this point, having said anything beyond the intended 90-day mission (now officially extended to 120 days after water was officially collected for the first time) is a gift to be savored. That Lazarus Tweet we'll be watching for with open hearts. Show that Winter who's boss, little fella! [Twitter]

 | Dwarf galaxies of varying brightness orbiting the Milky Way have a common central mass, says a new study that suggests dark matter can provide the minimum mass required for galaxies to form. |
Mickey Mouse bridges the culture war when teaching evolution to evangelical students

David Campbell managed to slip evolution into the high-school science curriculum in the conservative Florida town where he teaches -- by using images of Mickey Mouse through the years to illustrate the principle:
On the projector, Campbell placed slides of the cartoon icon: one at his skinny genesis in 1928, one from his 1940 turn as the impish "Sorcerer's Apprentice," and one of the rounded, ingratiating charmer of Mouse Club fame.Teacher shows that science, religion don't have to clash (Thanks, Andrew!)"How," he asked his students, "has Mickey changed?"
Natives of Disney World's home state, they waved their hands and called out answers.
"His tail gets shorter," Bryce volunteered.
"Bigger eyes!" someone else shouted.
"He looks happier," one girl observed. "And cuter."
Campbell smiled. "Mickey evolved," he said. "And Mickey gets cuter because Walt Disney makes more money that way. That is 'selection.' "
