Former NASA Administrator Daniel Goldin pioneered a "faster, better, cheaper" approach to America's space program, but he would have been hard-pressed to deliver a Mars mission for the bargain-basement price of India's first probe to the red planet, which blasted off Tuesday.
A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable.
That's the conclusion of a new analysis of observations taken by NASA's Kepler Space Telescope, which was launched in 2009 to hunt for potentially habitable Earth-like planets around other stars.

A new study suggests there could be far more Earth-like planets orbiting distant stars than once thought, some of which might even harbor life.
A team of astronomers from the University of California, Berkeley and the University of Hawaii at Manoa, Honolulu, used the Kepler space telescope to survey 42,000 Sun-like stars looking for a telltale dimming caused by an orbiting planet as it crosses between us and the parent star.

Food porn or art? That's for you decide.
But one thing is for certain: The jumbo-sized images in The Photography of Modernist Cuisine are truly awesome.
In one, a ham and cheese sandwich levitates in midair. Then, a Weber grill gets sliced in half lengthwise to expose a pink burger cooking on another page. And blueberries and peas balloon to the size of dinner plates and melons.
Maltreatment during childhood can lead to long-term changes in brain circuits that process fear, researchers say. This could help explain why children who suffer abuse are much more likely than others to develop problems like anxiety and depression later on.
The Large Stone Carving is the heaviest stone in the Forbidden City in Beijing. It was believed to have weighed more than 300 tons when it was first transported to the site between 1407 and 1420.

Judging from a carving found in an Egyptian tomb, experts say 172 men were used to transport the 60-ton Statue of Tehuti-Hetep, circa 1880 B.C. Water was used to lubricate the colossus as it slid along wooden planks.
The distance between the Forbidden City in Beijing (a) and the Dasiwo Quarry in Fangshan (b) is about 43 miles. Double lines on the map represent rivers; single lines represent roads.

The Cape Hatteras Lighthouse in Buxton, N.C., was moved almost 3,000 feet inland on July 9, 1999, to protect it from the advancing ocean.
Great works of ancient engineering, like the Pyramids or Stonehenge, inspire awe in every beholder. But some onlookers also get inspired to figure out exactly how these structures were made.
Howard Stone, an engineer from Princeton University, had such a moment in Beijing's Forbidden City — a city-within-a-city of palaces and temples built in the 15th and 16th centuries. A carved, 300-ton slab that formed a ramp to one structure particularly caught Stone's eye. "How in the world did it get here?" he wondered.

Sportvision creates its on-screen graphics, like the Virtual Yellow 1st & Ten line, with infrared sensors attached to uniforms and positioned around the stadium. The line shows viewers how far the offense has to advance the ball to earn a first down.
