nasagoddard NASA's STEREO (Behind) satellite captured this magnificent coronal mass ejection (associated with an M-class flare) that flung a long stream of plasma into space (Aug. 24, 2014). We have combined a view of the Sun in extreme UV light with a broader visible light view of the Sun's corona. It is interesting to note that a lot of the plasma, lacking sufficient kinetic energy to break free from the Sun's gravity, was pulled back into the Sun.

So with that ferocious belch out and then the recoil back to the beautiful Sun..do the photons that gravity grabbed reach their kinetic zenith and elongate or instantaneously reverse direction at the speed of light? Scary and beautiful ! Also so much of the plasma snaps back home from soo far away as you pointed out..gravity says, "weak force huh? Watch me now" 12min

nasagoddard This new NASA/ESA Hubble Space Telescope image shows a variety of intriguing cosmic phenomena.

Surrounded by bright stars, towards the upper middle of the frame we see a small young stellar object (YSO) known as SSTC2D J033038.2+303212. Located in the constellation of Perseus, this star is in the early stages of its life and is still forming into a fully-grown star. In this view from Hubble’s Advanced Camera for Surveys(ACS) it appears to have a murky chimney of material emanating outwards and downwards, framed by bright bursts of gas flowing from the star itself. This fledgling star is actually surrounded by a bright disk of material swirling around it as it forms — a disc that we see edge-on from our perspective.

However, this small bright speck is dwarfed by its cosmic neighbor towards the bottom of the frame, a clump of bright, wispy gas swirling around as it appears to spew dark material out into space. The bright cloud is a reflection nebula known as [B77] 63, a cloud of interstellar gas that is reflecting light from the stars embedded within it. There are actually a number of bright stars within [B77] 63, most notably the emission-line star LkHA 326, and it nearby neighbor LZK 18.

These stars are lighting up the surrounding gas and sculpting it into the wispy shape seen in this image. However, the most dramatic part of the image seems to be a dark stream of smoke piling outwards from [B77] 63 and its stars — a dark nebula called Dobashi 4173. Dark nebulae are incredibly dense clouds of pitch-dark material that obscure the patches of sky behind them, seemingly creating great rips and eerily empty chunks of sky. The stars speckled on top of this extreme blackness actually lie between us and Dobashi 4173.

nasagoddard NASA Sees Massive Marie Close Enough to Affect Southern California Coast

On August 26 at 19:05 UTC (3:05 p.m. EDT) NASA's Terra satellite captured a visible image of Hurricane Marie drawing in the small remnants of Karina. Marie is over 400 miles in diameter, about the distance from Washington, D.C. to Boston, Massachusetts. Hurricane force winds extend outward up to 60 miles (95 km) from the center and tropical storm force winds extend outward up to 205 miles (335 km). Because of Marie's large size and its movement to the north, it is creating rough surf that is now reaching southern California's shoreline. The National Hurricane Center noted that swells generated by Marie will continue to affect much of the west coast of the Baja California, Mexico peninsula and now including the extreme southern Gulf of California and southern California through Thursday, August 28. Life-threatening surf and rip current conditions are likely as a result of these swells as well as minor coastal flooding.

At 11 a.m. EDT (1500 UTC) Marie's maximum sustained winds had decreased to near 75 mph (120 kph). Marie was centered near latitude 22.3 north and longitude 123.7 west. That's about 880 miles (1,415 km) west of the southern tip of Baja California, Mexico. Marie is moving toward the west-northwest near 14 mph (22 kph) and is expected to turn to the northwest.

As Marie moves in a northerly direction it will be moving over progressively colder waters so the National Hurricane Center forecasts additional weakening in the next two days. My Thursday, Marie is expected to become a post-tropical cyclone.

nasagoddard NASA Telescopes Uncover Early Construction of Giant Galaxy

Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate.

The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii, and the European Space Agency's Herschel space observatory, in which NASA plays an important role.

A fully developed elliptical galaxy is a gas-deficient gathering of ancient stars theorized to develop from the inside out, with a compact core marking its beginnings. Because the galactic core is so far away, the light of the forming galaxy that is observable from Earth was actually created 11 billion years ago, just 3 billion years after the Big Bang.

nasagoddard The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future.

As one of the first objects observed by NASA’s Chandra X-ray Observatory after its launch some 15 years ago, this double star system continues to reveal new clues about its nature through the X-rays it generates.
Astronomers reported extremely volatile behavior from Eta Carinae in the 19th century, when it became very bright for two decades, outshining nearly every star in the entire sky. This event became known as the “Great Eruption.” Data from modern telescopes reveal that Eta Carinae threw off about ten times the sun’s mass during that time. Surprisingly, the star survived this tumultuous expulsion of material, adding “extremely hardy” to its list of attributes.
Today, astronomers are trying to learn more about the two stars in the Eta Carinae system and how they interact with each other. The heavier of the two stars is quickly losing mass through wind streaming away from its surface at over a million miles per hour. While not the giant purge of the Great Eruption, this star is still losing mass at a very high rate that will add up to the sun’s mass in about a millennium.

nasagoddard On the evening of May 23, 2014, several supercell thunderstorms rumbled along the border between North and South Carolina and dropped significant amounts of hail. Much of the hail was quarter-sized, but the strongest storms unloaded chunks of ice as large as baseballs, according to National Weather Service staff in Columbia, South Carolina. As observers on the ground documented the hail pummeling the ground, NASA’s high-flying ER-2 aircraft flew high overhead.

During one flight, pilot Stu Broce took this photograph of the overshooting top of a storm over North Carolina. For perspective, the storm was about 50,000 feet (15,000 meters) tall, while the ER-2 cruised at an altitude of 65,000 feet (20,000 meters). (Commercial airliners usually fly at about 30,000 feet or 9,000 meters.) Overshooting tops are dome-like protrusions at the top of thunderstorms that provide evidence of very strong updrafts. Severe storms tend to have larger and longer-lived overshooting tops than less intense storms.

The ER-2 flight was part of the Integrated Precipitation and Hydrology Experiment (IPHEx), a field campaign designed to improve understanding of precipitation over mountainous terrain.

nasagoddard Tropical Storm Lowell Becomes 7th Eastern Pacific Hurricane of the season.

NOAA's GOES-West satellite watched as Tropical Storm Lowell strengthened into a large hurricane during the morning of August 21 and opened its eye.

Hurricane force winds extend outward up to 60 miles (95 km) from the center, while tropical storm force winds extend outward up to 185 miles (295 km). The storm stretches over a greater distance.

Lowell became the seventh hurricane of the Eastern Pacific Ocean season today, August 21 at 11 a.m. EDT (1500 UTC). Maximum sustained winds had increased to 75 mph (120 kph) making Lowell a Category One hurricane on the Saffir-Simpson Wind Scale. Little change in intensity is forecast by the National Hurricane Center (NHC) today, and NHC forecasters expect a slow weakening trend later today through August 22.

The NHC said that Lowell should begin to slowly weaken by August 22 as it moves over progressively cooler waters and into a drier and more stable air mass. Since Lowell is such a large cyclone, it will likely take longer than average to spin down.

nasagoddard Blue Marble, Eastern Hemisphere -- Image acquired March 30, 2014.

Of all the planets NASA has explored, none have matched the dynamic complexity of our own. Earth is constantly changing, and NASA are working constantly to explore and understand the planet on scales from local to global.

Though Earth science has been a key part of NASA’s mission since the agency was founded in 1958, this year has been one of the peaks. Two new Earth-observing satellites have already been launched and put to work: the Global Precipitation Measurement (GPM) and the Orbiting Carbon Observatory 2 (OCO-2). Three more missions are set to take off in the next six months: the wind-measuring ISS-RapidScat, the ISS Cloud-Aerosol Transport System (CATS), and the Soil Moisture Active Passive (SMAP). And research planes have been flying over polar ice, hurricanes, boreal forests, and pollution plumes.

nasagoddard How the Sun Caused an Aurora This Week -- On the evening of Aug. 20, 2014, the International Space Station was flying past North America when it flew over the dazzling, green blue lights of an aurora. On board, astronaut Reid Wiseman captured this image of the aurora, seen from above.

This auroral display was due to a giant cloud of gas from the sun – a coronal mass ejection or CME – that collided with Earth's magnetic fields on Aug. 19, 2014, at 1:57 a.m. EDT. This event set off, as it often does, what's called a geomagnetic storm. This is a kind of space weather event where the magnetic fields surrounding Earth compress and release. This oscillation is much like a spring moving back and forth, but unlike a spring, moving magnetic fields cause an unstable environment, setting charged particles moving and initiating electric currents.

nasagoddard Hubble Stirs Up Galactic Soup

This new NASA/ESA Hubble Space Telescope image shows a whole host of colorful and differently shaped galaxies; some bright and nearby, some fuzzy, and some so far from us they appear as small specks in the background sky. Together they appear as kind of galactic soup.

The most prominent characters are the two galaxies on the left — 2MASX J16133219+5103436 at the bottom, and its blue-tinted companion SDSS J161330.18+510335 at the top. The latter is slightly closer to us than its partner, but the two are still near enough to one another to interact. Together, the two make up a galactic pair named Zw I 136.

Both galaxies in this pair have disturbed shapes and extended soft halos. They don’t seem to conform to our view of a “typical” galaxy — unlike the third bright object in this frame, a side-on spiral seen towards the right of the image.

nasagoddard Hubble Revisits a Globular Cluster’s Age -- Globular clusters are big balls of old stars that orbit around their host galaxy. It has long been believed that all the stars within a globular cluster form at the about same time, a property which can be used to determine the cluster's age. For more massive globulars however, detailed observations have shown that this is not entirely true — there is evidence that they instead consist of multiple populations of stars born at different times. One of the driving forces behind this behavior is thought to be gravity: more massive globulars manage to grab more gas and dust, which can then be transformed into new stars.

nasagoddard Exploring our galaxy's dark side -- Clouds of gas and dust fill the space between the stars. Like giant puffs of smoke, these cosmic particles have a tendency to obscure objects from detection. But by using NASA's Spitzer Space Telescope, researchers can look through the clouds and see the heat radiated from distant stars, planets and even other galaxies. Since 2003, the telescope has utilized wavelengths in the infrared spectrum to uncover a hidden universe of never-before-seen places and phenomenon. Here are four mind-blowing images of the Milky Way taken by Spitzer.

nasagoddard This may look like a work of abstract art, but in reality, it's our Moon and is for science.

The Lunar Reconnaissance Orbiter Camera, or LROC, is a system of three cameras mounted on the Lunar Reconnaissance Orbiter (LRO) that capture high resolution photos of the lunar surface.

This colorful image is an LROC slope map of the northwestern portion of the floor of Posidonius crater. Warmer colors indicate steeper slopes, whereas cooler colors are shallower slopes. A rille winds its way across the floor and flows along a southerly course, diverging from its path along the crater rim. A tributary rille (or narrow channel) can be seen joining the main rille at the bottom center. Image width is approximately 3.4 miles. North is up.

nasagoddard In this image, we line up a 1972 photograph of our magnetic coil facility at NASA Goddard with a shot of the facility as it appears today. The old photo shows testing of the #Apollo 17 #moon rover - which measured the moon's magnetic field in December.
Scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, calibrated the magnetometers on the lunar rover. These instruments are still used today to detect magnetic fields emitted by ore deposits, solar storms, submarines, and buried treasure. During the Apollo missions, engineers had outfitted the rover with these instruments to find out how the moon was formed. The scientists used this coil facility in order to ensure that the rover’s magnetometer did not accidentally measure its own hardware’s magnetic field. The astronauts found no magnetic field resembling the one we have here on Earth.
By sending electric currents through the metal coils, the magnetic facility can nullify a geomagnetic field the size of an elephant. NASA uses this method to calibrate magnetometers on spacecraft. The Magnetospheric Multiscale satellites’ have already have passed through to calibrate instruments that measure space weather. The entire Deep Space Climate Observatory will enter the chamber in August to correct for its EPIC camera’s magnetism. In addition, the MAVEN spacecraft that will arrive in orbit around Mars in September is outfitted with two magnetometers to observe how solar wind interacts with the Martian atmosphere. #TBT #ThrowbackThursday #DearPhotograph

nasagoddard The Sunshield on NASA's James Webb Space Telescope is the largest part of the observatory—five layers of thin membrane that must unfurl reliably in space to precise tolerances. Last week, for the first time, engineers stacked and unfurled a full-sized test unit of the Sunshield and it worked perfectly.

The Sunshield is about the length of a tennis court, and will be folded up like an umbrella around the Webb telescope’s mirrors and instruments during launch. Once it reaches its orbit, the Webb telescope will receive a command from Earth to unfold, and separate the Sunshield's five layers into their precisely stacked arrangement with its kite-like shape.

The Sunshield separates the observatory into a warm sun-facing side and a cold side where the sunshine is blocked from interfering with the sensitive infrared instruments. The infrared instruments need to be kept very cold (under 50 K or -370 degrees F) to operate. The Sunshield protects these sensitive instruments with an effective sun protection factor or SPF of 1,000,000 (suntan lotion generally has an SPF of 8-50). In addition to providing a cold environment, the Sunshield provides a thermally stable environment. This stability is essential to maintaining proper alignment of the primary mirror segments as the telescope changes its orientation to the sun.

nasagoddard NASA's Chandra X-ray Observatory Celebrates 15th Anniversary

Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision.

Chandra, one of NASA's current "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray emission from hot and energetic regions of the universe.

To celebrate Chandra's 15th anniversary, these four new images of supernova remnants – the Crab Nebula, Tycho, G292.0+1.8, and 3C58 – are being released. These supernova remnants are very hot and energetic and glow brightly in X-ray light, which allows Chandra to capture them in exquisite detail.
