The sun is ramping up toward solar maximum -- the white-hot peak of activity in an 11-year cycle -- and NASA has been snapping images of the phenomenon every 12 seconds for three years. The space agency put together a three-minute video showing images taken by the Solar Dynamic Observatory since spring 2010. As the Los Angeles Times' Deborah Netburn reported last month, the NASA video stitches together two SDO images per day over the three-year period. Alex Young, a heliophysicist at Goddard Space Flight Center, narrates the video to point up some of the sun's best-of moments in that time frame.

One of NASA's prize workhorses, the spacecraft Galaxy Evolution Explorer, or GALEX, was decommissioned Friday after 10 years of scanning the universe in ultraviolet light. “It had a long run,” said Karl Forster, GALEX science operations center team leader. The satellite, only 6 feet tall and a svelte 1,034 pounds, was part of NASA's small Explorer mission. Its main objective was to use ultraviolet cameras to take images of young stars, which are invisible to human eyes because they emit only UV light.

It's not just the stars that twinkle in the dark of night. The Earth is twinkling too. NASA has released new, spectacular images of our planet at night, from a satellite orbiting 512 miles above the Earth's surface. The agency stitched some of these images together to create a composite image of the entire planet. They call it the Black Marble. But the cobweb of city lights that stretch over the planet is just one of the images that the super sensitive light sensor captured. It also sent back images of Auroras over Antarctica, volcanoes and natural gas flares.

What happens to our DNA, RNA and proteins if we spend a long time in space? A pair of 50-year-old twins will help NASA find out. Identical twins Mark and Scott Kelly have signed up to be part of the first-ever twin study that takes place, at least partially, in space. In March 2015, veteran astronaut Scott Kelly will begin a one-year stint living aboard the International Space Station. It will be the longest amount of consecutive time that any American astronaut has spent in space. His brother Mark Kelly, who is married to former Arizona Rep. Gabrielle Giffords, will stay on Earth and serve as a control in the study.

Charles used to work at NASA and wants to stay in touch with the space program via NASA TV, the cable channel paid for by tax dollars and provided free to telecom companies. Turns out, though, that his AT&T U-verse package doesn't include NASA TV. To receive the channel, he was told, he'd have to pay for a more expensive programming package. More videos from Ask Laz Charles' question: Why should NASA TV be considered a premium channel considering that taxpayers have already paid for it?

A quirky habit of German insomniacs and "chill-out" music fans has come to world attention thanks to the U.S. government shutdown. "Space Night," a nearly 20-year-old late-night broadcast by Bavarian Television, provides a music-sharing platform against a backdrop of NASA's video feed from the International Space Station. But the 15-day-old U.S. government shutdown has idled the NASA archivists responsible for relaying the imagery beyond Mission Control, cutting off fresh backdrops to mix with the music for "Space Night" broadcasts that were to have launched a new season Nov. 1. NASA archivists were put on unpaid leave at the start of October, when 700,000 government workers whose jobs weren't deemed essential to defense and security were furloughed until the contentious U.S. Congress passes a budget for the new fiscal year.

With her long blond ponytail floating above her inside the International Space Station, astronaut Karen Nyberg calmly explains the challenges of quilting in weightlessness. "Now that I've tried my hand sewing in space," she said in a video released Thursday by NASA, "I can say one thing with certainty: It's tricky. " As if being a mechanical engineer and astronaut isn't significant enough, the avid quilter brought sewing supplies including fabric, scissors, thread, five needles (but no pins)

Having trouble getting excited about NASA's planned mission to redirect an asteroid? Maybe William Gerstenmaier can help. "Turn off your logical side and turn on your touchy-feely side, the one you almost never use," Gerstenmaier, associate administrator for NASA's Human Exploration and Operations Directorate, told attendees of an aeronautics and astronautics conference Wednesday in San Diego. "Then jump up and down and do some break-dancing. We're going to grab a space rock and we're going to move it!"

The search for Earth-like planets, and ultimately life beyond Earth, is about to get a boost: In 2017, NASA will send a satellite called TESS into orbit with the goal of finding planets in our solar neighborhood that may be hospitable to life. NASA's Kepler mission has been scanning a small portion of the sky since 2009 in search of planets that orbit stars other than our own, but the Transiting Exoplanet Survey Satellite mission will be scanning...

NASA reached outside its own organization today and appointed an industry expert as the head of a new safety office to guard against a repetition of the Challenger disaster. George A. Rodney, director of mission success at the Martin-Marietta Orlando Aerospace Co. in Florida, will have charge of all safety, reliability and quality assurance functions in NASA activities.
