Hubble Space Telescope finds source of Magellanic Stream

August 9, 2013 10:05 am | News | Comments

Astronomers have solved a 40-year-old mystery on the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around our Milky Way galaxy. It appears to originate from two dwarf galaxies, but astronomers did not know if one or both galaxies were the source. Hubble Space Telescope’s Cosmic Origins Spectrograph was used to examine the gas and find the answer.

A year of Curiosity on Mars

August 7, 2013 3:06 pm | Videos | Comments

Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.

Astronomers image lowest-mass exoplanet around a sun-like star

August 5, 2013 6:22 pm | by Francis Reddy, NASA's Goddard Space Flight Center | News | Comments

Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b and still glowing from the heat of its formation, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.

New Doppler radar takes flight on this summer’s HS3 mission

August 1, 2013 4:30 pm | by Ellen Gray, NASA Goddard Space Flight Center | News | Comments

The Severe Storm Sentinel, or HS3, mission will fly this year to investigate Atlantic Ocean hurricanes. It will carry a new type of dual-frequency conical-scanning Doppler radar that sports a new shape: Most aircraft carrying Doppler radar look like they’ve grown a tail, developed a dorsal fin, or sprouted a giant pancake on their backs. But the unmanned Global Hawk carries will carry the radar under its belly as it flies above hurricanes.

After studying data from a pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, researchers at Los Alamos National Laboratory believe they have solved a lingering mystery about how electrons within Earth’s radiation belt can suddenly become energetic enough to kill orbiting satellites.

IRIS telescope offers first glimpse of sun’s mysterious atmosphere

July 25, 2013 6:37 pm | News | Comments

On July 17, 2013, the international team which supported and built NASA's Interface Region Imaging Spectrograph, or IRIS, was rewarded for its hard work when the door of the telescope opened to view the mysterious lowest layers of the sun's atmosphere in unprecedented detail. Imaging in ultraviolet light and using a spectrograph, the orbiter has already revealed a multitude of previously unseen structures.

Curiosity rover confirms Martian air is mostly CO2

July 22, 2013 9:20 am | by Alicia Chang, AP Science Writer | News | Comments

The measurements by the most advanced spacecraft to land on the red planet closely match what the twin Viking landers detected in the late 1970s and what scientists have gleaned from Martian meteorites. Mars' atmosphere is overwhelmingly dominated by carbon dioxide, unlike Earth's air, which is a mix of nitrogen and oxygen. But Curiosity’s measurements did yield one small surprise.

How Mars’ atmosphere got so thin

July 22, 2013 9:01 am | News | Comments

New findings from NASA's Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today. The beauty of these measurements lies in the fact that these are the first really high-precision measurements of the composition of Mars' atmosphere.

Biotechnology company Zero Gravity Solutiuons aims to utilize the unique effects of extended zero/micro gravity environments available on the International Space Station to promote gene expression and accelerate stem cell research. The company has completed filings required prior to trading of the company’s stock.

Spacesuit water leak ends spacewalk; astronaut OK

July 17, 2013 9:56 am | by Marcia Dunn, AP Aerospace Writer | News | Comments

In one of the most harrowing spacewalks in decades, an astronaut had to rush back into the International Space Station on Tuesday after a mysterious water leak inside his helmet robbed him of the ability to speak or hear at times and could have caused him to choke or even drown. Italian Luca Parmitano was reported to be fine after the dangerous episode, which might have been caused by an unprecedented leak in the cooling system of his suit.

Report: Next Mars rover should gather rocks, soil

July 17, 2013 9:09 am | News | Comments

The next rover to Mars should hunt for signs of ancient life and gather rocks that a future mission could bring back to Earth for the first time, a team of scientists appointed by the U.S. space agency said Tuesday. The scientists' new report outlines ambitious goals for a mission to Mars that NASA wants to launch in 2020.

The heart of space weather observed in action

July 16, 2013 9:22 am | by Karen C. Fox, NASA Goddard Space Flight Center | News | Comments

Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun.

Astronomers find blue planet outside solar system

July 15, 2013 8:15 am | by James Brooks, Associated Press | News | Comments

Astronomers have for the first time managed to determine the color of a planet outside our solar system, a blue gas giant 63 light-years away. Measuring the planet's color, which is probably created by a turbulent atmosphere of silicate particles, is a significant first. It has never been done before with a planet outside our solar system.

New NASA satellite to begin sun-watching mission

June 28, 2013 4:30 am | by The Associated Press | News | Comments

From its perch in low-Earth orbit, NASA's newest satellite will soon get a close-up look at a little-explored region of the sun that's thought to drive space weather that can affect Earth. The Iris satellite was boosted into orbit about 400 miles above Earth by a Pegasus rocket Thursday evening after a sunset launch. Engineers will test the satellite first before turning on its telescope to stare at the sun.

The science of impact: "Shields to maximum, Mr. Scott"

June 27, 2013 2:43 pm | by Aaron Dubrow, TACC | News | Comments

According to NASA, there are more than 21,000 pieces of “space junk roughly the size of a baseball in orbit, and about 500,000 pieces that are golf ball-sized. These pieces can be dangerous, which is why researchers at Texas Advanced Computing Center’s supercomputers are simulating orbital debris impacts on spacecraft and fragment impacts on body armor to help NASA design better shielding.

“One giant leap” toward a NASA Armstrong center?

June 11, 2013 7:25 am | by Alicia Chang, AP Science Writer | News | Comments

Neil Armstrong's name is attached to a lunar crater, an asteroid, more than a dozen schools and a museum, but not a single NASA facility is christened in honor of the man whose "giant leap" made him the first to walk on the moon. All that could soon change on the fringes of the Mojave Desert, where leaders at the space agency's top flight research center are mulling a name change.
