Hubble telescope zeroes in on green blob in space
NASA releases new pictures of a mysterious gaseous object that is "giving birth to new stars"
This handout photo provided by NASA, taken April 12, 2010 by the Hubble Space Telescope, shows an unusual, ghostly green blob of gas appears to float near a normal-looking spiral galaxy. NASA released Monday the Hubble Space Telescopes first picture of the mysterious giant glowing green blob of gas called Hannys Voorwerp. The blob is the size of our Milky Way galaxy and is 650 million light years away. Each light year is about 6 trillion miles. The blob was discovered in 2007 by Dutch school teacher Hanny van Arkel.

The bizarre glowing blob is giving birth to new stars, some only a couple million years old, in remote areas of the universe where stars don’t normally form.
The blob of gas was first discovered by a Dutch school teacher in 2007 and is named Hanny’s Voorwerp (HAN’-nee’s-FOR’-vehrp). Voorwerp is Dutch for object.
NASA released the new Hubble photo Monday at the American Astronomical Society meeting in Seattle.
Parts of the green blob are collapsing and the resulting pressure from that is creating the stars. The stellar nurseries are outside of a normal galaxy, which is usually where stars live.
That makes these “very lonely newborn stars” that are “in the middle of nowhere,” said Bill Keel, the University of Alabama astronomer who examined the blob.
The blob is the size of our own Milky Way galaxy and it is 650 million light years away. Each light year is about 6 trillion miles.
The blob is mostly hydrogen gas swirling from a close encounter of two galaxies and it glows because it is illuminated by a quasar in one of the galaxies. A quasar is a bright object full of energy powered by a black hole.
The blob was discovered by elementary school teacher Hanny van Arkel, who was 24 at the time, as part of a worldwide Galaxy Zoo project where everyday people can look at archived star photographs to catalog new objects.
Van Arkel said when she first saw the odd object in 2007 it appeared blue and smaller. The Hubble photo provides a clear picture and better explanation for what is happening around the blob.
“It actually looked like a blue smudge,” van Arkel told The Associated Press. “Now it looks like dancing frog in the sky because it’s green.” She says she can even see what passes for arms and eyes.
Since van Arkel’s discovery, astronomers have looked for similar gas blobs and found 18 of them. But all of them are about half the size of Hanny’s Voorwerp, Keel said.

Secret papers turn up heat on global-warming deniers
Purloined, secret documents suggest the Heartland Institute could have lobbying plans, in violation of IRS rules
(Credit: Reuters) With Al Gore way down in Antarctica inspecting melting glaciers, and America’s unusually mild winter providing a respite from seasons of freakish droughts, floods, Nome-style whiteouts and the hurricane that ravaged Vermont, the issue of man-caused global warming has been out of sight and mind.
But virtually all scientists continue to believe that most indicators suggest the world as we know it is slowly ending, and that humans are to blame. Nature – oceans, deserts, crops, animals and insects – is in the process of being transformed by rising temperatures due to the fuel we burn to stay warm or cool, and to power factories, cars and jets. In the academies, the argument now is only between experts who predict “bad” and those who predict “catastrophe.”

Last space shuttle comes home, ends 30-year era
The Atlantis touched down at Kennedy Space Center for the last time early this morning
Space Shuttle Atlantis lands at the Kennedy Space Center at Cape Canaveral, Fla. Thursday, July 21, 2011. The landing of Atlantis marks the end of NASA's 30 year space shuttle program. (AP Photo/Don Emmert, Pool)(Credit: AP) Atlantis and four astronauts returned from the International Space Station in triumph Thursday, bringing an end to NASA’s 30-year shuttle journey with one last, rousing touchdown that drew cheers and tears.
A record crowd of 2,000 gathered near the landing strip, thousands more packed Kennedy Space Center and countless others watched from afar as NASA’s longest-running spaceflight program came to a close.
“After serving the world for over 30 years, the space shuttle’s earned its place in history. And it’s come to a final stop,” commander Christopher Ferguson radioed after Atlantis glided through the ghostly twilight and landed on the runway.

When we dreamed of being astronauts
NASA's last flight marks the end of an era, but for space geeks like me, it's a different kind of loss
A photo of the author's Major Matt Mason figurine. With the final mission of the space shuttle looming on Friday, NASA puts a lid on five decades of U.S. space exploration with nary an ace left up its sleeve. Let’s face it, hitching future rides out of a launch facility in Kazakhstan doesn’t constitute a program so much as a glorified car service. And while some enthusiasts might feel a bit of a black hole each time they look skyward, I only need glance at the upper corner of my computer monitor to experience a sense of loss.
For the last 25 years, from the time I landed my first job out of college in 1986, the year Challenger went go at throttle up and then went no more, a small, bendable astronaut named Major Matt Mason has been perched atop my display.

Gabrielle Giffords makes first public appearance
Recovering congresswoman stands, waves at NASA ceremony in Houston honoring her husband
ADDS ADDITIONAL SOURCING INFORMATION - This most recent photo of U.S. Rep. Gabrielle Giffords since she was shot, was posted to her public Facebook page by her aides early Sunday, June 12, 2011. The woman in the background is her mother Gloria Giffords. The photo was taken May 17, 2011 at TIRR Memorial Hermann Hospital in Houston, the day after the launch of space shuttle Endeavour and the day before she had her cranioplasty. Giffords could be released from a rehabilitation hospital in Houston sometime this month, a top aide says, offering the latest indication that the Arizona congresswoman is making progress in recovering from a gunshot wound to the head. (AP Photo/southwestphotobank.com, P.K. Weis) MANDATORY CREDIT(Credit: AP) An aide to Rep. Gabrielle Giffords says she appeared in front of a crowd of hundreds at a NASA awards ceremony in Houston.
ABC News reported on its website Monday night that Giffords stood up from her wheelchair to hug and kiss her astronaut husband, Mark Kelly, after he received the Spaceflight Medal.
ABC News says the 41-year-old Democrat from Tucson, Ariz., entered the auditorium at Space Center Houston while being pushed in the wheelchair. She smiled and waved at the crowd and received a standing ovation.
Giffords spokesman C.J. Karamargin confirmed that Giffords attended the ceremony.
Giffords has been in the Houston area undergoing rehabilitation since several weeks after the Jan. 8 shooting in Tucson that left her and 12 others wounded and six people dead.
