Combining almost opposite ends of the electromagnetic spectrum, this composite of the Herschel in far-infrared and XMM-Newton’s X-ray images shows how the hot young stars detected by the X-ray observations are sculpting and interacting with the surrounding ultra-cool gas and dust, which, at only a few degrees above absolute zero, is the critical material for star formation itself. Both wavelengths would be blocked by Earth’s atmosphere, so are critical to our understanding of the lifecycle of stars      ( विद्युत चुम्बकीय वर्णक्रम , दूर अवरक्त और XMM - न्यूटन एक्स - रे छवियों में Herschel के इस समग्र के लगभग विपरीत छोर के संयोजन से पता चलता है कि कैसे गर्म युवा सितारों में एक्स - रे की टिप्पणियों से पता चला sculpting और आसपास के अल्ट्रा शांत गैस के साथ बातचीत कर रहे हैं और धूल , जो केवल शून्य निरपेक्ष ऊपर कुछ डिग्री पर , स्टार गठन ही के लिए महत्वपूर्ण सामग्री है . दोनों तरंगदैर्य पृथ्वी के वायुमंडल द्वारा अवरुद्

Two spacecraft engineers join a grouping of vehicles providing a comparison of three generations of Mars rovers developed at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The setting is JPL's Mars Yard testing area. Front and center is the flight spare for the first Mars rover, Sojourner, which landed on Mars in 1997 as part of the Mars Pathfinder Project. On the left is a Mars Exploration Rover Project test rover that is a working sibling to Spirit and Opportunity, which landed on Mars in 2004. On the right is a Mars Science Laboratory test rover the size of that project's Mars rover, Curiosity, which is on course for landing on Mars in August 2012. Sojourner and its flight spare, named Marie Curie, are 2 feet (65 centimeters) long. The Mars Exploration Rover Project's rover, including the "Surface System Test Bed" rover in this photo, are 5.2 feet (1.6 meters) long. The Mars Science Laboratory Project's Curiosity rover and &q

Flying past Saturn's moon Dione, Cassini captured this view which includes two smaller moons, Epimetheus and Prometheus, near the planet's rings. The image was taken in visible light with Cassini's narrow-angle camera during the spacecraft's flyby of Dione on Dec. 12, 2011. This encounter was the spacecraft's closest pass of the moon's surface, but, because this flyby was intended primarily for other Cassini instruments, it did not yield Cassini's best images of the moon. Higher resolution images were obtained during earlier flybys (see PIA07638). Dione (698 miles, or 1,123 kilometers across) is closest to Cassini here and is on the left of the image. Potato-shaped Prometheus (53 miles, or 86 kilometers across) appears above the rings near the center top of the image. Epimetheus (70 miles, or 113 kilometers across) is on the right. This view looks toward the northern, sunlit side of the rings from less than one degree above the ring pl

With space shuttle Atlantis' 25-year spaceflight career now in the history books, its next mission -- to inform and inspire generations of visitors to the Kennedy Space Center Visitor Complex in Florida -- is one step closer to reality. A groundbreaking ceremony Jan. 18 officially launched construction of a new 65,000-square-foot exhibit at the complex's Space Shuttle Plaza, where NASA's fourth space-rated orbiter will be the main attraction. This artist rendering reveals a full-scale external tank and twin solid rocket booster replicas standing at the exhibit entrance.

The Multi-Purpose Crew Vehicle (MPCV), or Orion, being assembled and tested at Lockheed Martin's Vertical Testing Facility in Colorado. Drawing from more than 50 years of spaceflight research and development, Orion is designed to meet the evolving needs of our nation's space program for decades to come. As the flagship of our nation's next-generation space fleet, Orion will push the envelope of human spaceflight far beyond low Earth orbit. Orion may resemble its Apollo-era predecessors, but its technology and capability are light years apart. Orion features dozens of technology advancements and innovations that have been incorporated into the spacecraft's subsystem and component design. A test version of the Orion spacecraft makes a stop at the Science Museum Oklahoma in Oklahoma City today, giving residents the chance to see a full scale test version of the vehicle that will take humans into deep space.

 mosaic of images taken in mid-January 2012 shows the windswept vista northward (left) to northeastward (right) from the location where NASA's Mars Exploration Rover Opportunity is spending its fifth Martian winter, an outcrop informally named "Greeley Haven." Opportunity's Panoramic Camera (Pancam) took the component images as part of full-circle view being assembled from Greeley Haven. The view includes sand ripples and other wind-sculpted features in the foreground and mid-field. The northern edge of the the "Cape York" segment of the rim of Endeavour Crater forms an arc across the upper half of the scene. Opportunity landed on Mars on Jan. 25, 2004, Universal Time and EST (Jan. 24, PST). It has driven 21.4 miles (34.4 kilometers) as of its eighth anniversary on the planet. In late 2011, the rover team drove Opportunity up onto Greeley Haven to take advantage of the outcrop's sun-facing slope to boost output from the rover's

Three proposed aircraft designs have varying levels of success in meeting tough NASA goals for reducing fuel use, emissions and noise all at the same time.   The Boeing Company's advanced design concept is a variation on the extremely aerodynamic hybrid wing body.    Lockheed Martin's concept uses a box wing design and other advanced technologies to achieve green aviation goals.    Northrop Grumman's concept is based on the extremely aerodynamic "flying wing" design.  Leaner, greener flying machines for the year 2025 are on the drawing boards of three industry teams under contract to the NASA Aeronautics Research Mission Directorate's Environmentally Responsible Aviation Project. Teams from The Boeing Company in Huntington Beach, Calif., Lockheed Martin in Palmdale, Calif., and Northrop Grumman in El Segundo, Calif., have spent the last year studying how to meet NASA goals to develop technology that would allow future aircraft to burn

A 'Blue Marble' image of the Earth taken from the VIIRS instrument aboard NASA's most recently launched Earth-observing satellite - Suomi NPP. This composite image uses a number of swaths of the Earth's surface taken on January 4, 2012. The NPP satellite was renamed 'Suomi NPP' on January 24, 2012 to honor the late Verner E. Suomi of the University of Wisconsin. Suomi NPP is NASA's next Earth-observing research satellite. It is the first of a new generation of satellites that will observe many facets of our changing Earth. Suomi NPP is carrying five instruments on board. The biggest and most important instrument is The Visible/Infrared Imager Radiometer Suite or VIIRS.

When scientists discovered two great swaths of radiation encircling Earth in the 1950s, it spawned over-the-top fears about "killer electrons" and space radiation effects on Earthlings. The fears were soon quieted: the radiation doesn't reach Earth, though it can affect satellites and humans moving through the belts. Nevertheless, many mysteries about the belts – now known as the Van Allen Radiation belts – remain to this day. Filled with electrons and energetic charged particles, the radiation belts swell and shrink in response to incoming solar energy, but no one is quite sure how. Indeed, what appears to be the same type of incoming energy has been known to cause entirely different responses on different occasions, causing increased particles in one case and particle loss in another. Theories on just what causes the belts to swell or shrink abound, with little hard evidence to distinguish between them. One big question has simply been to determine if, w

MOFFET FIELD, Calif. -- NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form. The planets orbit close to their host stars and range in size from 1.5 times the radius of Earth to larger than Jupiter. Fifteen are between Earth and Neptune in size. Further observations will be required to determine which are rocky like Earth and which have thick gaseous atmospheres like Neptune. The planets orbit their host star once every six to 143 days. All are closer to their host star than Venus is to our sun. "Prior to the Kepler mission, we knew of perhaps 500 exoplanets across the whole sky," said Doug Hudgins, Kepler program scientist at NASA Headquarters in Washington. "Now, in
