"Today we remember and give thanks for the lives and contributions of those who gave all trying to push the boundaries of human achievement. On this solemn occasion, we pause in our normal routines and remember the STS-107 Columbia crew; the STS-51L Challenger crew; the Apollo 1 crew; Mike Adams, the first in-flight fatality of the space program as he piloted the X-15 No. 3 on a research flight; and those lost in test flights and aeronautics research throughout our history. These men and women were our friends, family and colleagues. They still are. As we undertake a journey to Mars, they will be with us. They have our eternal respect, love and gratitude." - NASA Administrator Charles Bolden In this image, Bolden speaks to NASA personnel and others during a wreath laying ceremony as part of NASA's Day of Remembrance, Wednesday, Jan. 28, 2015, at Arlington National Cemetery in Arlington, Va. The wreaths were laid in memory of those men and women who lost their lives in the quest for space exploration. Photo Credit: (NASA/Joel Kowsky) #nasa #nasaremembers; -
The year of 2015 has been declared the International Year of Light (IYL) by the United Nations. Organizations, institutions, and individuals involved in the science and applications of light will be joining together for this yearlong celebration to help spread the word about the wonders of light. In many ways, astronomy uses the science of light. And to celebrate, our Chandra X-ray Observatory released new images. Here's one of them: This supernova remnant is the remains of an exploded star that may have been witnessed by Chinese astronomers almost 2,000 years ago. Modern telescopes have the advantage of observing this object in light that is completely invisible to the unaided human eye. This image combines X-rays from Chandra (pink and blue) along with visible emission from hydrogen atoms in the rim of the remnant, observed with the 0.9-m Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory (yellow).

Ready for Thursday's Launch: The sun sets behind Space Launch Complex 2 (SLC-2) with the Delta II rocket and the Soil Moisture Active Passive (SMAP) observatory protected by the service structure on Tuesday, Jan. 27, 2015, at Vandenberg Air Force Base, Calif. SMAP is our first Earth-observing satellite designed to collect global observations of surface soil moisture and its freeze/thaw state. SMAP will provide high resolution global measurements of soil moisture from space. The data will be used to enhance scientists' understanding of the processes that link Earth's water, energy, and carbon cycles.

Sometimes it takes a village to find new and unusual objects in space. Volunteers scanning tens of thousands of starry images from NASA's Spitzer Space Telescope, using the Web-based Milky Way Project, recently stumbled upon a new class of curiosities that had gone largely unrecognized before: yellow balls. The rounded features are not actually yellow -- they just appear that way in the infrared, color-assigned Spitzer images. Volunteers using the web-based Milky Way Project brought star-forming features nicknamed "yellowballs" to the attention of researchers, who later showed that they are a phase of massive star formation. "With prompting by the volunteers, we analyzed the yellow balls and figured out that they are a new way to detect the early stages of massive star formation," said Charles Kerton of Iowa State University, Ames. "The simple question of 'Hmm, what's that?' led us to this discovery." Image Credit: NASA/JPL-Caltech #nasa #spitzer #telescope #mikyway #galaxy #yellowballs #milkywayproject #science; -

In many ways, astronomy uses the science of light. And to celebrate, our Chandra X-ray Observatory released new images. Here's one of them: This galaxy, at a distance of some 700 million light years, contains a giant bubble filled with hot, X-ray emitting gas detected by Chandra (blue). Radio data from the NSF's Very Large Array (red) reveal "hot spots" about 300,000 light years out from the center of the galaxy where powerful jets emanating from the galaxy's supermassive black hole end. Visible light data (yellow) from both Hubble and the DSS complete this view.

Light shines on new views: The year of 2015 has been declared the International Year of Light (IYL) by the United Nations. Organizations, institutions, and individuals involved in the science and applications of light will be joining together for this yearlong celebration to help spread the word about the wonders of light. In many ways, astronomy uses the science of light. And to celebrate, our Chandra X-ray Observatory released new images. Here's one of them: When X-rays, shown in blue, from Chandra and XMM-Newton are joined in this image with radio data from the Australia Telescope Compact Array (pink) and visible light data from the Digitized Sky Survey (DSS, yellow), a new view of the region emerges. This object, known as MSH 11-62, contains an inner nebula of charged particles that could be an outflow from the dense spinning core left behind when a massive star exploded.

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. The spiraling arcs of magnetic field lines emerge from active regions and connect back to areas with the opposite polarity. The field lines are more concentrated where regions are more magnetically intense. They rotate with the rotation of the Sun. Credit: NASA/Solar Dynamics Observatory; -
A Whirlpool of Light: The year of 2015 has been declared the International Year of Light (IYL) by the United Nations. Organizations, institutions, and individuals involved in the science and applications of light will be joining together for this yearlong celebration to help spread the word about the wonders of light. In many ways, astronomy uses the science of light. And to celebrate, our Chandra X-ray Observatory released new images. Here's one of them: This galaxy, nicknamed the "Whirlpool," is a spiral galaxy, like our Milky Way, located about 30 million light years from Earth. This composite image combines data collected at X-ray wavelengths by Chandra (purple), ultraviolet by the Galaxy Evolution Explorer (GALEX, blue); visible light by Hubble (green), and infrared by Spitzer (red).

Meanwhile, 60 million light-years away from Earth, the spiral galaxy NGC 4217, spotted by the Hubble Space Telescope. The galaxy is seen almost perfectly edge on and is a perfect candidate for studying the nature of extraplanar dust structures — the patterns of gas and dust above and below the plane on the galaxy, seen here as brown wisps coming off NGC 4217. These tentacle-like filaments are visible in the Hubble image only because the contrast with their surroundings is so high. This implies that the structures are denser than their surroundings. The image shows dozens of dust structures some of which reach as far as 7,000 light-years away from the central plane. Typically the structures have a length of about 1,000 light-years and are about 400 light-years in width. Credit: ESA/Hubble & NASA, Acknowledgement: R.

#TBT to 1964 when the TIROS 9 weather satellite launched from the Kennedy Space Center. This Satellite was NASA’s first attempt to place a satellite in a near polar-sun synchronous orbit. Another quality making the TIROS 9 unique were its two-cameras, mounted 180 degrees opposite each other. The TIROS 9 Satellite remained active until June 12, 1968, giving the Satellite a total life-span of 1,238 days. Image: Pictured is the TIROS 9 Satellite, with a clear view of one of the sides of its two cameras.; -
The year of 2015 has been declared the International Year of Light (IYL) by the United Nations. Organizations, institutions, and individuals involved in the science and applications of light will be joining together for this yearlong celebration to help spread the word about the wonders of light. In many ways, astronomy uses the science of light. By building telescopes that can detect light in its many forms, from radio waves on one end of the "electromagnetic spectrum" to gamma rays on the other, scientists can get a better understanding of the processes at work in the Universe. To celebrate, our Chandra X-ray Observatory released new images. Here's one of them: When a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way, it left behind an expanding shell of debris called SNR 0519-69.0. Here, multimillion degree gas is seen in X-rays from Chandra (blue). The outer edge of the explosion (red) and stars in the field of view are seen in visible light from Hubble.

Greenland's Leidy Glacier: Located in the northwest corner of Greenland, Leidy Glacier is fed by ice from the Academy Glacier (upstream and inland). As Leidy approaches the sea, it is diverted around the tip of an island that separates the Olriks Fjord to the south and Academy Cove to the north. The resulting crisscross pattern is simply the result of ice flowing along the path of least resistance. This view of the region pictured above was acquired Aug. 7, 2012, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on our Terra satellite. In April 2012, the feature caught the attention of one of our pilots, who snapped this picture from the cockpit of a high-flying ER-2 aircraft during a research flight over the Greenland ice cap.

The Large Binocular Telescope Interferometer (LBTI) instrument set its eyes on a dusty star system called Eta Corvi, depicted here in this artist's concept. Recent collisions between comets and rocky bodies within the star system are thought to have generated the surplus of dust. Evidence for this barrage comes from our Spitzer Space Telescope, whose infrared detectors picked up indications that one or more comets was recently torn to shreds after colliding with a rocky body. In this artist's conception, one such giant comet is shown smashing into a rocky planet, flinging ice- and carbon-rich dust into space, while also smashing water and organics into the surface of the planet. A glowing red flash captures the moment of impact on the planet. Yellow-white Eta Corvi is shown to the left, with still more comets streaming toward it.
