“Red and Dead Galaxies” - Our Chandra X-ray Observatory is shedding new light on the mystery of why giant elliptical galaxies have few, if any, young stars. This new evidence highlights the important role that supermassive black holes play in the evolution of their host galaxies. Because star-forming activity in many giant elliptical galaxies has shut down to very low levels, these galaxies mostly house long-lived stars with low masses and red optical colors. Astronomers have therefore called these galaxies "red and dead”.

Observing a Gigantic Eruption of Solar Material - A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail. This was the first CME observed by the Interface Region Imaging Spectrograph, or IRIS, which launched in June 2013 to peer into the lowest levels of the sun's atmosphere with better resolution than ever before. A video of the IRIS imagery shows how a curtain of solar material erupts outward at speeds of 1.5 million miles per hour. Image Credit: NASA #sun #solar #nasa #sdo #iris #science; -
IceBridge Concludes Arctic Field Campaign - Researchers with our Operation IceBridge have completed another successful Arctic field campaign. On May 23, NASA's P-3 research aircraft left Thule Air Base, Greenland, and returned to Wallops Flight Facility in Virginia marking the end of 11 weeks of polar research. During this campaign, researchers collected data on Arctic sea and land ice - both repeating measurements on rapidly changing areas and expanding coverage into new, unsurveyed regions. The mission also released two sea ice data products and provided a professional development opportunity for three science teachers. This image is a view of mountains and sea ice near Thule Air Base, Greenland, from the NASA P-3 on May 6, 2014.

Orion Heat Shield Attached! The world's largest heat shield, measuring 16.5 feet in diameter, has been successfully attached to the Orion spacecraft. The heat shield is made from a single seamless piece of Avcoat ablator. It will be tested on Orion's first flight in December 2014 as it protects the spacecraft from temperatures reaching 4000 degrees Fahrenheit. The uncrewed flight, dubbed Exploration Flight Test-1(EFT-1), will test the spacecraft for eventual missions that will send astronauts to an asteroid and eventually Mars. EFT-1 will launch an uncrewed Orion capsule 3,600 miles into space for a four-hour mission to test several of its most critical systems. After making two orbits, Orion will return to Earth at almost 20,000 miles per hour, before its parachutes slow it down for a landing in the Pacific Ocean.

Violent Birth Announcement from an Infant Star - This Hubble image shows IRAS 14568-6304, a young star that is cloaked in a haze of golden gas and dust. It appears to be embedded within an intriguing swoosh of dark sky, which curves through the image and obscures the sky behind. This dark region is known as the Circinus molecular cloud. This cloud has a mass around 250 000 times that of the sun, and it is filled with gas, dust and young stars. Within this cloud lie two prominent and enormous regions known colloquially to astronomers as Circinus-West and Circinus-East. Each of these clumps has a mass of around 5000 times that of the sun, making them the most prominent star-forming sites in the Circinus cloud. The clumps are associated with a number of young stellar objects, and IRAS 14568-6304, featured here under a blurry fog of gas within Circinus-West, is one of them.

We demonstrated that we can land an unmanned spacecraft on a rugged planetary surface in the pitch dark in a free-flight test Wednesday of the Morpheus prototype lander and Autonomous Landing Hazard Avoidance Technology, or ALHAT. The 98-second test began at 10:02 p.m. EDT, with the Morpheus lander launching from the ground over a flame trench and ascending more than 800 feet (244 m) into the dark Florida sky at Kennedy Space Center using only ALHAT's Hazard Detection System for guidance. The Hazard Detection System, assisted by three light detection and ranging (lidar) sensors, located obstacles -- such as rocks and craters -- and safely landed on the lunar-like hazard field a quarter mile away from the NASA Center. These new capabilities could be used in future efforts to deliver cargo to planetary surfaces. Image Credit: NASA/Mike Chambers #nasa #morpheus #ksc #spacecraft; -
Coming together - At the Operations and Checkout Building at Kennedy Space Center, the Orion crew module and heat shield are being moved into position for the mating operation. The heat shield will be tested on Orion's first flight in December, Exploration Flight Test-1 (EFT-1), an uncrewed flight that will put to the test the spacecraft that will send astronauts to an asteroid and eventually Mars on future missions. EFT-1 will launch an uncrewed Orion capsule 3,600 miles into space for a four-hour mission to test several of its most critical systems. After making two orbits, Orion will return to Earth at almost 20,000 miles per hour and endure temperatures near 4,000 degrees Fahrenheit, before its parachutes slow it down for a landing in the Pacific Ocean.

The 'Serpent' Star-forming Cloud Hatches New Stars - Within the swaddling dust of the Serpens Cloud Core, astronomers are studying one of the youngest collections of stars ever seen in our galaxy. Infrared light has been assigned colors we see with our eyes, revealing young stars in orange and yellow, and a central parcel of gas in blue. This area is hidden in visible-light views, but infrared light can travel through the dust, offering a peek inside the stellar hatchery. The dark patch to the left of center is swaddled in so much dust, even the infrared light is blocked. It is within these dark wombs that stars are just beginning to take shape.

Sunsets on Titan Reveal the Complexity of Hazy Exoplanets - Using data collected by Cassini’s Visual and Infrared Mapping Spectrometer, or VIMS, while observing Titan’s sunsets, researchers created simulated spectra of Titan as if it were a planet transiting across the face of a distant star. The research helps scientists to better understand observations of exoplanets with hazy atmospheres. This image is an artist’s rendering of our Cassini spacecraft observing a sunset through Titan’s hazy atmosphere.

Airborne Research Focuses on Andean Volcanoes - Volcanoes in Central and South America were the primary focus of a four-week Earth science study in late April and early May 2014 using a NASA-developed airborne synthetic aperture imaging radar. The synthetic aperture radar developed by the Jet Propulsion Laboratory mounted on NASA's C-20A research aircraft captured this image of Peru's Ubinas volcano on April 14, 2014, during its Latin American research mission. The false colors represent different polarizations in the image. Image Credit: NASA JPL UAVSAR / Ron Muellerschoen #nasa #volcano #peru #ubinas #earth #earthrightnow; -
