NASA decommissions its galaxy hunter spacecraft

July 1, 2013 ? NASA has turned off its Galaxy Evolution Explorer (GALEX) after a decade of operations in which the venerable space telescope used its ultraviolet vision to study hundreds of millions of galaxies across 10 billion years of cosmic time.

"GALEX is a remarkable accomplishment," said Jeff Hayes, NASA's GALEX program executive in Washington. "This small Explorer mission has mapped and studied galaxies in the ultraviolet, light we cannot see with our own eyes, across most of the sky."

Operators at Orbital Sciences Corporation in Dulles, Va., sent the signal to decommission GALEX at 12:09 p.m. PDT (3:09 p.m. EDT) Friday, June 28. The spacecraft will remain in orbit for at least 65 years, then fall to Earth and burn up upon re-entering the atmosphere. GALEX met its prime objectives and the mission was extended three times before being cancelled.

Highlights from the mission's decade of sky scans include:

• Discovering a gargantuan, comet-like tail behind a speeding star called Mira.
• Catching a black hole "red-handed" as it munched on a star.
• Finding giant rings of new stars around old, dead galaxies.
• Independently confirming the nature of dark energy.
• Discovering a missing link in galaxy evolution -- the teenage galaxies transitioning from young to old.

The mission also captured a dazzling collection of snapshots, showing everything from ghostly nebulas to a spiral galaxy with huge, spidery arms.

In a first-of-a-kind move for NASA, the agency in May 2012 loaned GALEX to the California Institute of Technology in Pasadena, which used private funds to continue operating the satellite while NASA retained ownership. Since then, investigators from around the world have used GALEX to study everything from stars in our own Milky Way galaxy to hundreds of thousands of galaxies 5 billion light-years away.

In the space telescope's last year, it scanned across large patches of sky, including the bustling, bright center of our Milky Way. The telescope spent time staring at certain areas of the sky, finding exploded stars, called supernovae, and monitoring how objects, such as the centers of active galaxies, change over time. GALEX also scanned the sky for massive, feeding black holes and shock waves from early supernova explosions.

"In the last few years, GALEX studied objects we never thought we'd be able to observe, from the Magellanic Clouds to bright nebulae and supernova remnants in the galactic plane," said David Schiminovich of Columbia University, N.Y., N.Y, a longtime GALEX team member who led science operations over the past year. "Some of its most beautiful and scientifically compelling images are part of this last observation cycle."

Data from the last year of the mission will be made public in the coming year.

"GALEX, the mission, may be over, but its science discoveries will keep on going," said Kerry Erickson, the mission's project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

JPL managed the GALEX mission and built the science instrument. The mission's principal investigator, Chris Martin, is at Caltech. NASA's Goddard Space Flight Center in Greenbelt, Md., developed the mission under the Explorers Program it manages. Researchers sponsored by Yonsei University in South Korea and the Centre National d'Etudes Spatiales (CNES) in France collaborated on the mission. Caltech manages JPL for NASA.

Gay marriage opponents ask court to intervene

SAN FRANCISCO (AP) ? A wave of weddings were performed in San Francisco City Hall on the heels of the U.S. Supreme Court's historic decisions to restore same-sex marriages to California, as defeated backers of the state's gay marriage ban filed a last-ditch effort to halt the ceremonies.

Less than 24 hours after California started issuing marriage licenses to same sex couples, lawyers for the Arizona-based Alliance Defending Freedom filed an emergency petition to the high court Saturday asking it to halt the weddings on the grounds that its decision was not yet legally final. They claimed the 9th U.S. Circuit Court of Appeals acted prematurely and unfairly on Friday when it allowed gay marriage to resume by lifting a hold that had been placed on same sex unions.

The motion was filed as dozens of couples in jeans, shorts, white dresses and the occasional military uniform filled City Hall to obtain marriage licenses. On Friday, 81 same sex couples received marriage licenses.

Although a few clerk's offices around the state stayed open late on Friday, San Francisco, which is holding its annual gay pride celebration this weekend, was the only jurisdiction to hold weekend hours so that same sex couples could take advantage of their newly restored right, Clerk Karen Hong said.

A sign posted on the door of the office where a long line of couples waited to fill out applications listed the price for a license, a ceremony or both above the words "Equality=Priceless."

"We really wanted to make this happen," Hong said, adding that her whole staff and a group of volunteers came into work without having to be asked. "It's spontaneous, which is great in its own way."

The timing couldn't have been better for California National Guard Capt. Michael Potoczniak, 38, and his partner of 10 years, Todd Saunders, 47, of El Cerrito.

Potoczniak, who joined the Guard after the military's ban on openly gay service was repealed almost two years ago, was scheduled to fly out Sunday night for a month of basic training in Texas.

"I woke up this morning, shook him awake and said, 'Let's go,'" said Potoczniak, who chose to get married in his Army uniform. "It's something that people need to see because everyone is so used to uniforms at military weddings."

Also waiting to wed Saturday were Scott Kehoe, 34, and his fiance, Aurelien Bricker, 24. After finding out on Facebook that the city was issuing same sex marriage licenses Friday, the San Francisco couple rushed out to Tiffany's to buy wedding rings.

"We were afraid of further legal challenges in the state," Kehoe said.

The Supreme Court ruled on Wednesday that Proposition 8's backers lacked standing to defend the 2008 law because California's governor and attorney general have declined to defend the ban.

Then on Friday, the 9th Circuit appeared to have removed the last obstacle to making same sex matrimony legal again in California when it removed its hold on a lower court's 2010 order directing state officials to stop enforcing the ban.

Within hours, same sex couples were seeking marriage licenses. The two couples who sued to overturn Proposition 8 were wed in San Francisco and Los Angeles Friday.

Alliance Defending Freedom Senior Counsel Austin Nimocks said on Saturday that the high court's consideration of the case isn't done because his clients still have 22 days to ask the justices to reconsider Wednesday's 5-4 decision.

Under Supreme Court rules, the losing side in a legal dispute has 25 days to request a rehearing. While such requests are almost never granted, the high court said that it wouldn't finalize its judgment in the case at least until after that waiting period elapsed.

The San Francisco-based appeals court had said when it imposed the stay that it would remain in place until the Supreme Court issued its final disposition, according to Nimocks.

"Everyone on all sides of the marriage debate should agree that the legal process must be followed," he said. "On Friday, the 9th Circuit acted contrary to its own order without explanation."

Many legal experts who had anticipated such a last-ditch effort by gay marriage opponents said it was unlikely to succeed because the 9th Circuit has independent authority over its own orders ? in this case, its 2010 stay.

While the ban's backers can still ask the Supreme Court for a rehearing, the 25-day waiting period is not binding on lower federal courts, Vikram Amar, a constitutional law professor with the University of California, Davis law school, said.

"As a matter of practice, most lower federal courts wait to act," Amar said. "But there is nothing that limits them from acting sooner. It was within the 9th Circuit's power to do what it did."

The city, home to both a federal trial court that struck down Proposition 8 as unconstitutional and the 9th Circuit, has been the epicenter of the state's gay marriage movement since then-Mayor Gavin Newsom ordered his administration in February 2004 to issue licenses to gay couples in defiance of state law.

A little more than four years later, the California Supreme Court, which is also based in San Francisco, struck down the state's one-man, one-woman marriage laws.

City Hall was the scene of many more marriages in the 4 1/2 months before a coalition of religious conservative groups successfully campaigned for the November 2008 passage of Proposition 8, which amended the state constitution to outlaw same sex marriages.

Portland's New Streetlights Are Psychedelic, Carnivorous Plants

If you've seen one streetlight, you've pretty much seen them all. They're important, sure, but they're usually not much to look at. The lamps that just popped up across Portland are a little bit different. A little more like giant, carnivorous plants.

"Nepenthes" by Dan Corson is a collection of four, 17-foot tall light-up sculptures that devour sunlight, and spit it back out after sundown. Though they share their name with plants known for eating bugs and occasional small animals, these sculptures just soak up rays during the day with solar panels mounted on top, and use that energy to glow for about four hours after dark. Just run-of-the-mill synthetic photosynthesis for these plants.

Made from translucent fiberglass with embedded with LED lights formed around a steel spine, each of the four lamps is structurally identical, but has a uniquely wild color scheme that sets it apart from its brothers. All and all, they seem like a neat represention of the "urban jungle," and it's a good thing they're a little more urban than jungle. [Dan Corson via Designboom]
