This artist's concept shows the Wide-field Infrared Survey Explorer, or WISE spacecraft,
in its orbit around Earth. In September of 2013, engineers will attempt to bring the mission out of hibernation to hunt for more asteroids and comets in a project called NEOWISE.
From 2010 to 2011, the WISE mission scanned the sky twice in infrared light not just for asteroids and comets but also stars, galaxies and other objects. Back then, the asteroid-hunting portion of the mission was named NEOWISE, which combines the acronyms for near-Earth objects (NEOs) and WISE. NEOs are those asteroids with orbits that come relatively close to Earth. Now, in its second "lease on life," the mission will be dedicated to asteroid and comet surveying.

There are nearly 200 galaxies in this image from Spitzer.
These are part of the Perseus-Pisces supercluster of galaxies located 250 million light-years
away. Normally, galaxies beyond our Milky Way are hidden from view when they happen to fall
behind the plane of our galaxy. This is due to foreground dust standing in the way. Spitzer's Galactic Legacy Infrared Mid-Plane Survey Extraordinaire 360, or Glimpse 360 project, is pointing Spitzer away from the galactic center, to complete a full 360-degree scan of the Milky Way plane. It has captures many images in the process, such as this one, revealing hidden objects. Image credit: NASA/JPL-Caltech/University of Wisconsin |

2MASS image of IRAS 20306+4005, an object in the Infrared Astronomical Satellite (IRAS)
catalog of sources. Little is known about this object, but it appears to be a region of current massive star formation in
the Galactic plane and near the Cygnus 0B2 stellar association. This is the first known near-infrared image of this source.
Infrared-bright filaments of gas surround a young cluster of stars and young stellar objects still embedded in their natal
dusty molecular cloud. A large patch of heavily-obscuring dust is seen to the north of the nebula. 2MASS is ideal for
investigating the nature of many IRAS objects and other very young star-forming regions throughout the Galaxy.

The giant star Zeta Ophiuchi is having a "shocking" effect on the surrounding dust clouds in this Spitzer image.
Zeta Ophiuchi is a young, large and hot star located around 370 light-years away. It dwarfs our own sun in many ways -- it is about six times hotter, eight
times wider, 20 times more massive, and about 80,000 times as bright. It would be one of the brightest stars in the sky were it not largely obscured by foreground dust clouds. This massive star is travelling at a snappy pace of about 54,000 mph (24 kilometers per second), fast enough to break the sound barrier in the surrounding interstellar material. Because of this motion, it creates a spectacular bow shock ahead of its direction of travel (to the left). Image credit: NASA/JPL-Caltech |

RCW 38 is at a distance of ~1.7 kpc (~5500 light years) from us, near the famous Vela supernova remnant and the Gum nebula.
This starforming region contains a number of highly massive O stars embedded in a dense obscuring cloud. The stars are
about 2 million years old, indicating that star formation is ongoing is this relatively young region. As seen in the
2MASS near-infrared Image mosaic, the nebulosity associated with RCW 38 is extensive across
a large area, with dust lanes and patches running throughout. Other, smaller obscured star-forming regions are nearby, with
less-obscured young, massive stars and associated reflection nebulae also in the field.

This image of the dusty star WISE J180956.27-330500.2 (the orange star in the upper left) compares WISE
12- and 22-micron data (green and red, respectively) with IRAS 12 micron
data (blue). The star has brightened by a factor of 100 between the IRAS and WISE observations. This appears to
have been caused by a sudden eruption in the star around 15 years ago. Dust freshly created in this event
is heated by starlight and glows at infrared wavelengths.

Spitzer image of Herbig-Haro 34. This image shows two jets (green = 4.5 micron); the
jet on the left is buried behind a dark cloud, and thus cannot be seen in visible-light images. This image shows that
both of the twin jets are made up of identical knots of gas and dust, ejected one after another from the area around the
star. By studying the spacing of these knots, and knowing the speed of the jets from previous studies, astronomers were
able to determine that the visible jet (to the right of the star) punches its material out 4.5 years later than the counter-jet.

2MASS images of Uranus, Neptune, and their moons. Uranus and Neptune were observed serendipitously by
the 2MASS Southern Facility, during routine operations on 1998 June 7 and June 11 UT, respectively. Both planets appear very blue, i.e.,
they are not nearly as bright in the Ks band as in the shorter wavelength bands, due to more reflection of sunlight at short wavelengths
and to absorption of light by methane gas in their atmospheres.

This false-color 2MASS mosaic shows the intermediate-age Galactic supernova remnant IC 443, which is at a distance of about 1.5 kpc. What can be seen over this large area are two regions of near-infrared emission from the remnant. The bright bluish arc to the northeast appears to be line emission from excited iron in these remnant filaments, bright in the J band. Along the south, from east to west, is the interaction of the remnant with the nearby molecular cloud. The supernova shock is exciting 2.12-micron H_2 molecular line emission, very bright in the Ks band. Image credit: E. Kopan (IPAC). |

This false-color mosaic of the central region of the Coma cluster combines infrared and visible-light images to reveal thousands of faint objects (green). Follow-up observations showed that many of these objects, which appear here as faint green smudges, are dwarf galaxies belonging to the cluster. Two large elliptical galaxies, NGC 4889 and NGC 4874, dominate the cluster's center. The mosaic combines visible-light data from the Sloan Digital Sky Survey (color coded blue) with long- and short-wavelength infrared views (red and green, respectively) from NASA's Spitzer Space Telescope.

Herschel's observation of the star-forming cloud RCW 120 has revealed an embryonic star which looks set to turn into one of the biggest and brightest stars in our Galaxy within the next few hundred thousand years. It already contains eight to ten times the mass of the Sun and is still surrounded by an additional 2000 solar masses of gas and dust from which it can feed further. IRSA will provide seamless access to the Herschel archive as well as curation of Key Project enhanced products. Image credit: ESA/PACS/SPIRE/HOBYS Consortia |

NGC 2024, also known as the Flame Nebula, is located at a distance of 400-500 pc and is part of the Orion Molecular Cloud Complex (Orion B). To the south of the NGC 2024 region lies NGC 2023 (a well-studied photo-dissociation region) and the Horsehead Nebula. At near-infrared wavelengths as shown in this 2MASS image, a dense stellar cluster is revealed in the dark lane separating the two halves of the flame. Image credit: E. Kopan and R. Hurt (IPAC) |

Maffei 2 is the poster child for an infrared galaxy that is almost invisible to optical telescopes. Foreground dust clouds in the Milky Way block about 99.5% of its visible light, but this infrared image from NASAs Spitzer Space Telescope penetrates this dust to reveal the galaxy in all its glory. This Spitzer image clearly shows the unusual structure of Maffei 2. The strong central bar and asymmetric spiral arms help identify why the galaxy also harbors a starburst in its very core. Such dramatic bursts of star formation occur when massive amounts of dust and gas are driven into the center of a galaxy, often by gravitational interactions that create barred spiral structures in its disk.

The planetary nebula NGC1514 as seen by WISE. The object is actually a pair of stars -- one star is a dying giant somewhat heavier and hotter than our sun, and the other was an even larger star that has now contracted into a white dwarf. As the giant star ages, it sheds some its outer layers of material to form a large bubble around the two stars. Jets of material from the white dwarf are thought to have smashed into this bubble wall. The areas where the jets hit the cavity walls appear as orange rings in the WISE image. In this image, 3.4 microns is blue; 4.6-micron light is cyan; 12-micron light is green; and 22-micron light is red. IRSA hosts the WISE archive, with the first public data release on April 14, 2011.

The immense Andromeda galaxy M31 is captured in full in this new image from NASA's Wide-field Infrared Survey Explorer (WISE). The mosaic covers an area of five degrees across the sky. WISE used all four of its infrared detectors to capture this picture (3.4- and 4.6-micron light is colored blue; 12-micron light is green; and 22-micron light is red). Blue highlights mature stars, while yellow and red show dust heated by newborn, massive stars. IRSA hosts the WISE archive, with the first public data release in April 2011.

This image is a three-colour combination constructed from Planck's two highest frequency channels (557 and 857 GHz, corresponding to wavelengths of 540 and 350 micrometres), and an image at the shorter wavelength of 100 micrometres obtained with the Infrared Astronomical Satellite (IRAS). This combination effectively traces the dust: reddish tones correspond to temperatures as cold as 12 degrees above absolute zero, and whitish tones to significantly warmer ones (of order a few tens of degrees) in regions where massive stars are currently forming. Overall, the image shows local dust structures within 500 light years of the Sun. Image credit: ESA and the HFI Consortium, IRAS |

This infrared snapshot of a region in the constellation Carina near the Milky Way was taken shortly after NASA's Wide-field Infrared Survey Explorer (WISE) ejected its cover. The "first-light" picture shows thousands of stars and covers an area three times the size of the Moon. Over the course of the mission, WISE will take more than a million similar pictures covering the whole sky. The initial WISE data release at IRSA is scheduled for Spring 2011. This eight-second exposure shows infrared light from three of WISE's four wavelength bands: Blue, green and red correspond to 3.4, 4.6, and 12 microns, respectively.

Known throughout the world under various names -- Subaru to the Japanese, Matarii ("Little Eyes") to the natives of Tonga, Athur-ai ("The Stars of Hathor") to the ancient Egyptians -- the Pleiades (as it was known to the ancient Greeks) is a cluster of naked-eye stars located in the constellation Taurus, the Bull. This cluster is now known to be a collection of relatively young stars, their births having occurred only 100 to 125 million years ago. The brightest stars shown here are those visible to the naked eye on a clear winter's night and represent hot blue giants much more massive than our Sun; the faintest members of the cluster are faint red dwarfs only a tenth of the Sun's mass. The blue, green, and red channels of this three-color image were made from B-, R-, and I-band images, respectively, from the Digitized Sky Survey. Image courtesy of Inseok Song (U. Georgia) and created with Montage v3.0 using this script. |

A 5-arcminute square view around the exoplanet host star, Gliese 581, using data provided by FinderChart and combined into a three-color image by Montage. DSS1 Bj-band, DSS2 R-band, and 2MASS J-band images are color coded as blue, green and red, respectively. Not only is the high motion of Gliese 581 itself obvious over the three epochs (1955, 1991, and 1999), but also obvious are artifacts in the DSS1 and 2MASS image sets (click on image for annotations) and an unrelated (and uncataloged?) star of smaller proper motion to the south-southeast of Gliese 581. For more data sets on the exoplanet host star, see the IRSA-Vizier inventory service. |
