The brilliant explosions of dead stars

The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distances to galaxies and measure the ever-increasing rate at which our universe is stretching apart. Now, scientists show that a particular class of Type Ia supernovae that occur near youthful stars can improve these measurements with a precision of more than two times that achieved before. The findings will help light the way to understanding dark energy. Details: http://go.nasa.gov/1HNdkPG

Stepping Stones to NASA’s Human Missions Beyond

“That's one small step for (a) man; one giant leap for mankind.” When Neil Armstrong took his first steps on the moon, many strides came before to achieve that moment in history. The same is true for a human mission to Mars. One step towards that journey begins Friday, when NASA Astronaut Scott Kelly will begin his mission to make history as the first American to spend a year in space. http://1.usa.gov/1yCwHFX
