NASA's Johnson Space Center’s "Chamber A" in Houston is an enormous thermal vacuum testing chamber and now appears to be opening it's "mouth" to take in NASA's James Webb Space Telescope for testing.
The telescope and the Integrated Science Instrument Module (ISIM) are two of the three major elements that comprise the Webb telescope Observatory flight system and are being lifted into the chamber in this photo. The other is the Spacecraft Element (spacecraft bus and sunshield), which is currently under construction at Northrop Grumman Aerospace Systems (NGAS) in Redondo Beach, California.
The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Image Description: The Webb telescope enters the giant Chamber A thermal vacuum chamber at NASA Johnson. At this point, Webb consists of mirrors and instruments but has not yet been mated with the sunshield or spacecraft bus. Webb is on its back, golden hexagonal mirrors face up. The secondary mirror support structure is extended like a tripod above the primary mirrors. The telescope lies on black and silver support equipment. It is approaching the giant mouth of the cavernous test chamber. The chamber is filled with test equipment and people in cleanroom suits. One of them stands on top of a red lift at left.
In the center of star-forming region 30 Doradus lies a huge cluster containing some of the largest, hottest, and most massive stars known. These stars, known collectively as star cluster R136, were captured in the featured image in visible light by the Wide Field Camera 3 in 2009 peering through the Hubble Space Telescope. Gas and dust clouds in 30 Doradus, also known as the Tarantula Nebula, have been sculpted into elongated shapes by powerful winds and ultraviolet radiation from these hot cluster stars. The 30 Doradus Nebula lies within a neighboring galaxy known as the Large Magellanic Cloud and is located a mere 170,000 light-years away. via NASA ift.tt/1Qmpbqa
Legends collide in this dramatic vista of land, sea, and sky. The land is Iceland, specifically Vík í Mýrdal, a southern village known for its beautiful black sand beaches. The sea, the Atlantic Ocean, surrounds Reynisdrangar, a sea stack of eroded basaltic rock pillars that Icelandic folklore tells are the petrified remains of trolls once attempting to drag a three-masted ship onto land. Watching from overhead and shining bright on the upper right is the god of the sky, according to Greek mythology: the planet Jupiter. Also visible in the sky are several other Greek legends encapsulated as constellations, including a lion (Leo), a big bear (Ursa Major), and a water snake (Hydra). One might guess that all of this commotion caused the spectacular aurora pictured -- but really it was just explosions from the Sun. via NASA ift.tt/1TXUTuT
What's that inside the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. The nebula glows brightly in red light emitted by its most prominent element: hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. At the top right is the companion Fishhead Nebula. via NASA ift.tt/1jNXN9y
Mars will look good in Earth's skies over the next few days -- but not this good. To get a view this amazing, a spacecraft had to actually visit the red planet. Running across the image center, though, is one the largest canyons in the Solar System. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris remains unknown, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled. Several geologic processes have been identified in the canyon. The featured mosaic was created from over 100 images of Mars taken by Viking Orbiters in the 1970s. Tomorrow, Mars and Earth will pass the closest in 11 years, resulting in the red planet being quite noticeable toward the southeast after sunset. via NASA ift.tt/24eIt5s
This stunning panorama in southern skies was recorded on the colorful night of September 27/28 from Carnegie Las Campanas Observatory. A diffuse glow and dark rifts of the central Milky Way hang over domes of the twin 6.5 meter Magellan telescopes. But most eye-catching is the deep red glow of the Moon. Immersed in Earth's shadow during the much anticipated perigee-total-lunar eclipse, the Moon's surface reflects the light of sunsets and sunrises scattered and refracted into the planet's cone-shaped umbra. Along with the dramatic hue of the eclipsed Moon, other colors of that night captured by the sensitive digital camera include the red and green shades of atmospheric airglow. Viewers can also spot the Andromeda Galaxy below the Moon, seen as a tiny smudge through the reddish airglow and lights along the horizon. The Magellanic Clouds, satellite galaxies of the Milky Way, join in at the far left of the full panorama frame. via NASA ift.tt/1hcunj1
This interstellar canine is formed of cosmic dust and gas interacting with the energetic light and winds from hot young stars. The shape, visual texture, and color, combine to give the region the popular name Fox Fur Nebula. The characteristic blue glow on the left is dust reflecting light from the bright star S Mon, the bright star just below the top edge of the featured image. Textured red and black areas are a combination of the cosmic dust and reddish emission from ionized hydrogen gas. S Mon is part of a young open cluster of stars, NGC 2264, located about 2,500 light years away toward the constellation of the Unicorn (Monoceros). via NASA ift.tt/1RRhE5q

At left, a dramatic image sequence follows late September's total lunar eclipse above a rugged landscape and sea of clouds from the Canary island of La Palma. Composited in a circular fisheye projection, the brightness of the Full Perigee Moon changes drastically in transition from outside the total eclipse phase compared to its dim glow during the 72 minute long totality. At right, a single frame captures the dark red lunar disk in a moment during the total eclipse phase, the Moon deep within Earth's shadow. In fact, the size of the eclipsed Moon image at right approximately illustrates the relative size of Earth and Moon, when compared to the circular projection of the eclipse sequence. via NASA ift.tt/1KZrkp6

What's lighting up the Cigar Galaxy? M82, as this irregular galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81. This doesn't fully explain the source of the red-glowing outwardly expanding gas, however. Evidence indicates that this gas is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. The featured photographic mosaic highlights a specific color of red light strongly emitted by ionized hydrogen gas, showing detailed filaments of this gas. The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in infrared light, and can be seen in visible light with a small telescope towards the constellation of the Great Bear (Ursa Major). via NASA ift.tt/20NADOn

Leonid meteors rained down on planet Earth this week, the annual shower of dusty debris from the orbit of Comet 55P/Tempel-Tuttle. Leonids streak through this composite night skyview from a backyard observatory in southern Ontario. Recorded with camera fixed to a tripod, the individual frames capture the bright meteor activity throughout the night of November 16/17, about a day before the shower's very modest peak. The frames are registered to the fixed field of view, so the meteor trails are not all aligned to the background star field recorded that same evening when nebula-rich Orion stood above the southern horizon. As a result, the trails don't appear to point back to the shower's radiant in Leo, situated off the left edge of the star field frame. In fact, some trails could be of Taurid meteors, a shower also active in November, or even sporadic meteors, including a bright fireball with its reflection near the horizon. via NASA ift.tt/1Mrzass
Double, double toil and trouble; Fire burn, and cauldron bubble .... maybe Macbeth should have consulted the Witch Head Nebula. A frighteningly shaped reflection nebula, this cosmic crone is about 800 light-years away though. Its malevolent visage seems to glare toward nearby bright star Rigel in Orion, just off the right edge of this frame. More formally known as IC 2118, the interstellar cloud of dust and gas is nearly 70 light-years across, its dust grains reflecting Rigel's starlight. In this composite portrait, the nebula's color is caused not only by the star's intense bluish light but because the dust grains scatter blue light more efficiently than red. The same physical process causes Earth's daytime sky to appear blue, although the scatterers in planet Earth's atmosphere are molecules of nitrogen and oxygen. via NASA ift.tt/1WnLsog
Late Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for a STEM-themed sleepover, ready to learn about careers in Science, technology, engineering and math. The educational event offered young women a chance to meet working female scientists and to discover opportunities for women in STEM-related professions.
The teens kicked off the third annual STEM Girls Night In with an astronaut Q&A, talks from female scientists across disciplines and a collection of hands-on activities. The night culminated in a three-hour Mars rover competition and concluded with a late-night showing of “Hidden Figures.”

This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.
Much of the information contained in this image came from a single remote-sensing device-NASA’s Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor’s view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation dataset compiled by the U.S. Geological Survey’s EROS Data Center. MODIS observations of polar sea ice were combined with observations of Antarctica made by the National Oceanic and Atmospheric Administration’s AVHRR sensor—the Advanced Very High Resolution Radiometer. The cloud image is a composite of two days of imagery collected in visible light wavelengths and a third day of thermal infra-red imagery over the poles. Global city lights, derived from 9 months of observations from the Defense Meteorological Satellite Program, are superimposed on a darkened land surface map.

What is that unusual light in the sky? A common question, this particular light was not only bright but moving and expanding. It appeared just as the astrophotographer and his friend were photographing the Golden Gate Bridge in San Francisco, California against a more predictable night sky. They were not alone in seeing this unusual display -- at least hundreds of people in California reported a similar sight. The consensus of experienced sky observers was that the plume resulted from a rocket launch -- an explanation that was soon confirmed as an unpublicized test of a submarine-launched, unarmed, Trident II D5 nuclear missile. Such tests are not uncommon but do not usually occur just after sunset near a major metropolitan area -- when they are particularly noticeable to many people. Were plume images not posted to the Internet and quickly identified, such a sky spectacle might have been understood by some to be associated with more grandiose -- but incorrect -- explanations. via NASA ift.tt/1M6mZ46

This beautiful new image from Webb is a gift from a past star. In near-infrared light, supernova remnant Cassiopeia A (Cas A) resembles a shiny ornament.
With its powerful vision, Webb can detect the tiniest knots of sulfur, oxygen, argon and neon gas from the star. Embedded in the gas are dust and molecules that will eventually become part of new stars and planets.
See that blob in the bottom right? Scientists have nicknamed it Baby Cas A since it looks like a tiny version of Cas A itself. Baby Cas A is a light echo: Light from the supernova has reached and is warming the distant dust in this blob. Although Baby Cas A appears very close to Cas A, it’s actually about 170 light-years behind the supernova remnant.
Since its launch nearly two years ago, Webb has consistently awed us with its wondrous views of the universe. We’re looking forward to a new year of stunning science and imagery to come.

This image highlights several interesting features of supernova remnant Cassiopeia A as seen with Webb’s NIRCam (Near-Infrared Camera):
1. NIRCam’s exquisite resolution is able to detect tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself. Some filaments of debris are too tiny to be resolved even by Webb, meaning they are comparable to or less than 10 billion miles across (around 100 astronomical units). Researchers say this represents how the star shattered like glass when it exploded.
2. Circular holes visible in the MIRI image within the Green Monster, a loop of green light in Cas A’s inner cavity, are faintly outlined in white and purple emission in the NIRCam image—this represents ionized gas. Researchers believe this is due to the supernova debris pushing through and sculpting gas left behind by the star before it exploded.
3. This is one of a few light echoes visible in NIRCam’s image of Cas A. A light echo occurs when light from the star’s long-ago explosion has reached, and is warming, distant dust, which is glowing as it cools down.
4. NIRCam captured a particularly intricate and large light echo, nicknamed Baby Cas A by researchers. It is actually located about 170 light-years behind the supernova remnant.
Image description: The image is split into 5 boxes. A large image at the left-hand side takes up most of the image. There are four images along the right-hand side in a column, labeled 1, 2, 3, and 4. The 4 images in the column are zoomed-in areas of the larger square image on the left. The image on the left has a circular-shaped cloud of gas and dust with complex structure, with an inner shell of bright pink and orange filaments that look like tiny pieces of shattered glass. A zoom-in of this material appears in the box labeled 1. Around the exterior of the inner shell in the main image there are wispy curtains of gas that look like campfire smoke. Within the cavity of the inner shell, there are small circular bubbles outlined in white. Box 2 is a zoom-in on these circles. Scattered outside the nebula in the main image, there are also clumps of yellow dust. Boxes 3 and 4 are zoomed-in areas of these clumps. Box 4 highlights a particularly large clump at the bottom right of the main image that is detailed and striated.
