3527 Extended Gas in Active Galaxies
These Hubble Space Telescope images reveal a set of bizarre, greenish, looping, spiral, and braided shapes around eight active galaxies. These huge knots of dust and gas appear greenish because they are glowing predominately in light from photoionized oxygen atoms.Each galaxy hosts a bright quasar that may have illuminated the structures. The ethereal wisps outside the host galaxies were blasted, perhaps briefly, by powerful ultraviolet radiation from a supermassive black hole at the core of each galaxy. Material falling into the black hole was heated to a point where a brilliant searchlight beam traveled into deep space. Because the quasars are not bright enough now to account for the present glow of the blobs, they may be a record of something that happened in the past inside the host galaxies. The black holes may have been fueled through collisions between two galaxies, and the filaments may be forensic evidence for material tattered in the collision.

4020 Infrared Image of Galaxy Pair NGC 4302 and NGC 4298
This is an infrared image of the galaxy pair NGC 4302 and NGC 4298 taken with Hubble's Wide Field Camera 3. The infrared light pierces through the dust lanes and shows significantly more stars than seen in visible light. In the infrared, the edge-on NGC 4302 is brighter than in the visible view. The tilted galaxy NGC 4298's spiral arms aren't as obvious in infrared, because the infrared light glows through the dust that marks the arms in visible light. This image represents the sort of view the James Webb Space Telescope will have when it is launched in late 2018. Webb's infrared vision will slice through dust to see the stars embedded in it.

2670 Hubble Pinpoints Distant Galaxies in Deepest View of Universe
This is the deepest image of the universe ever taken in near-infrared light by NASA's Hubble Space Telescope. The faintest and reddest objects (left inset) in the image are galaxies that correspond to "look-back times" of approximately 12.9 billion years to 13.1 billion years ago. No galaxies have been seen before at such early epochs. These galaxies are much smaller than the Milky Way galaxy and have populations of stars that are intrinsically very blue. This may indicate the galaxies are so primordial that they are deficient in heavier elements, and as a result, are quite free of the dust that reddens light through scattering. The image was taken with Hubble's newly installed Wide Field Camera 3 (WFC3), which collects light from near-infrared wavelengths and therefore looks even deeper into the universe. The light from very distant galaxies is stretched out of the ultraviolet and visible regions of the spectrum into near-infrared wavelengths by the expansion of the universe. Hubble's WFC3 took this image in late August 2009 during a total of four days of pointing for 173,000 seconds of exposure time. Infrared light is invisible and therefore does not have colors that can be perceived by the human eye. The colors in the image are assigned comparatively short, medium, and long near-infrared wavelengths (blue, 1.05 microns; green, 1.25 microns; and red, 1.6 microns). The representation is "natural" in that blue objects appear blue and red objects look red. The faintest objects are about one-billionth as bright as can be seen with the naked eye. The galaxy distances are estimated from the infrared colors of their light. These Hubble observations are trailblazing a path for Hubble's successor, the James Webb Space Telescope (JWST), which will look even farther into the universe than Hubble, at infrared wavelengths. The JWST is planned to be launched in 2014.

3088 30 Doradus Nebula and Star Clusters
This is a Hubble Space Telescope image of a pair of star clusters that are believed to be in the early stages of colliding. The clusters lie in the gigantic 30 Doradus Nebula, which is 170,000 light-years from Earth. Hubble's circumstantial evidence for the impending collision comes from seeing an elongated structure in the cluster at upper left, and from measuring a different age between the two clusters. Also, there is an unusually large number of high-velocity stars expelled from the region. This is a normal byproduct of a process called core collapse, in which more-massive stars sink to the center of a cluster by ejecting lower-mass stars. However, both clusters are too young to have experienced core collapse. The ejected stars can be better explained if the two clusters are merging. This nearby example of cluster interaction yields insights into how star clusters may have formed in the early universe. The Hubble image at upper right was made with Wide Field Camera 3 observations taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen. The colors in the wide-field image, made with Hubble's Wide Field Camera 3 and the Advanced Camera for Surveys, represent the hot gas that dominates regions of the image. Red signifies hydrogen gas and blue, oxygen. Hubble made the photo mosaic in October 2011.

364 Hubble Views the Galileo Probe Entry Site on Jupiter
[left] - This Hubble Space Telescope image of Jupiter was taken on Oct. 5, 1995, when the giant planet was at a distance of 534 million miles (854 million kilometers) from Earth. The arrow points to the predicted site at which the Galileo Probe will enter Jupiter's atmosphere on December 7, 1995. At this latitude, the eastward winds have speeds of about 250 miles per hour (110 meters per second). The white oval to the north of the probe site drifts westward at 13 miles per hour (6 meters per second), rolling in the winds which increase sharply toward the equator. The Jupiter image was obtained with the high resolution mode of Hubble's Wide Field Planetary Camera 2 (WFPC2). Because the disk of the planet is larger than the field of view of the camera, image processing was used to combine overlapping images from three consecutive orbits to produce this full disk view of the planet. [right] - These four enlarged Hubble images of Jupiter's equatorial region show clouds sweeping across the predicted Galileo probe entry site, which is at the exact center of each frame (a small white dot has been inserted at the centered at the predicted entry site). The first image (upper left quadrant) was obtained with the WFPC2 on Oct. 4, 1995 at (18 hours UT). The second, third and fourth images (from upper right to lower right) were obtained 10, 20 and 60 hours later, respectively. The maps extend +/- 15 degrees in latitude and longitude. The distance across one of the images is about three Earth diameters (37,433 kilometers). During the intervening time between the first and fourth maps, the winds have swept the clouds 15,000 miles (24,000 kilometers) eastward.

3475 A Near-Infrared View of the Pillars of Creation
This NASA Hubble Space Telescope image, taken in near-infrared light, transforms the pillars into eerie, wispy silhouettes, which are seen against a background of myriad stars. The near-infrared light can penetrate much of the gas and dust, revealing stars behind the nebula as well as hidden away inside the pillars. Some of the gas and dust clouds are so dense that even the near-infrared light cannot penetrate them. New stars embedded in the tops of the pillars, however, are apparent as bright sources that are unseen in the visible image. The ghostly bluish haze around the dense edges of the pillars is material getting heated up by the intense ultraviolet radiation from a cluster of young, massive stars and evaporating away into space. The stellar grouping is above the pillars and cannot be seen in the image. At the top edge of the left-hand pillar, a gaseous fragment has been heated up and is flying away from the structure, underscoring the violent nature of star-forming regions. Astronomers used filters that isolate the light from newly formed stars, which are invisible in the visible-light image. At these wavelengths, astronomers are seeing through the pillars and even through the back wall of the nebula cavity and can see the next generations of stars just as they're starting to emerge from their formative nursery.

1616 A Distant Solar System (Artist's Concept)
This artist's concept depicts a distant hypothetical solar system, similar in age to our own. Looking inward from the system's outer fringes, a ring of dusty debris can be seen, and within it, planets circling a star the size of our Sun. This debris is all that remains of the planet-forming disc from which the planets evolved. Planets are formed when dusty material in a large disc surrounding a young star clumps together. Leftover material is eventually blown out by solar wind or pushed out by gravitational interactions with planets. Billions of years later, only an outer disc of debris remains. These outer debris discs are too faint to be imaged by visible-light telescopes. They are washed out by the glare of the Sun. However, NASA's Spitzer Space Telescope can detect their heat, or excess thermal emission, in infrared light. This allows astronomers to study the aftermath of planet building in distant solar systems like our own.

79 Gravitational Lens in Galaxy Cluster AC 114
The NASA Hubble Space Telescope photograph (left) shows a pair of L-shaped images with striking mirror-symmetry. These are thought to arise from a very distant galaxy seen through a cluster of foreground galaxies (right). The gravity of the galaxy cluster acts as a natural magnifying glass, bending and focusing the light of the more distant source into several images, each of which is apparently larger and brighter than would otherwise be the case. This rare combination of Hubble's powerful telescope mirrors and the natural telephoto lens gives astronomers unprecedented information on the nature of very distant galaxies, and on the distribution and nature of matter in the foreground cluster. The two compact objects in the center of the HST image are thought to be unrelated galaxies in the foreground cluster. The observations were made with Hubble's Wide Field Camera in one of the first long exposures (six hours) with the orbiting observatory.
3823 Replacing the Wide Field and Planetary Camera (1993)
Astronaut Jeffrey Hoffman removes Wide Field and Planetary Camera 1 (WFPC 1) during change-out operations. It is replaced with its more powerful successor, Wide Field and Planetary Camera 2, during Hubble’s first servicing mission in 1993. The camera, shaped something like a grand piano, weighs 610 pounds (277 kg) on Earth, but nothing in space. It can detect stars a billion times fainter than the ones we can see with our eyes. Most of Hubble's most popular pictures have been taken with this second camera.
