PIX4625133: Saturn and Mimas seen by the Cassini probe 18/01/2005 - Saturn and Mimas seen by Cassini spacecraft Jan. 18 2005 - The Mimas satellite photographed in front of Saturn by the Cassini probe on 18 January 2005 at a distance of 1.4 million km from the planet. The shadow of Saturn's rings is projected on the planet. Mimas drifts along in its orbit against the azure backdrop of Saturn's northern latitudes in this true color view. The long, dark lines on the atmosphere are shadows cast by the planet's rings. Saturn's northern hemisphere is presently relatively cloud - free, and rays of sunlight take a long path through the atmosphere. This results in sunlight being scattered at shorter (bluer) wavelengths, thus giving the northernmost latitudes their bluish appearance at visible wavelengths. At the bottom, craters on icy Mimas (398 kilometers, or 247 miles across) give the moon a dimpled appearance. Images taken using infrared (930 nanometers), green (568 nanometers) and ultraviolet (338 nanometers) spectral filters were combined. The colors have been adjusted to match closely what the scene would look like in natural color. The images were obtained using the Cassini spacecraft narrow angle camera on Jan. 18, 2005, at a distance of approximately 1.4 million kilometers (870,000 miles) from Saturn. Resolution in the image is 8.5 kilometers (5.3 miles) per pixel on Saturn and 7.5 kilometers (4.7 miles) per pixel on Mimas. The image has been contrast - enhanced to aid visibility / Bridgeman Images

PIX4625221: Saturn rings seen by Cassini - Saturn's rings from Cassini - Image obtained by the Cassini probe on November 26, 2008 at a distance of 1.1 million km from the planet. This natural color view shows the system of rings of Saturn up to ring F. The system of rings is composed from closest to Saturn to outermost by ring D, then C, B, the division of Cassini, A with division of Encke, F, G and E. This natural color mosaic, taken from 10 degrees below the illuminated side of the rings, shows, from left to right, radially outward from Saturn, the C ring (with its Colombo and Maxwell gaps); the B ring and the Cassini division beyond, with the intervening Huygens gap; the A ring (with its Encke and Keeler gaps); and, on the far right, the narrow F ring. The total span covers approximately 65,700 kilometers (40,800 miles). Although it is too faint to be seen here, the D ring is located just to the left of the C ring. The mosaic was constructed from 45 narrow - angle - camera images - - 15 separate sets of red, green and blue images - - taken over the course of about four hours, as Cassini scanned across the rings. The images in this view were obtained by Nasa's Cassini spacecraft on Nov. 26, 2008, at a distance of approximately 1.1 million kilometers (700,000 miles) from Saturn and at a sun - Saturn - spacecraft, or phase, angle of 28 degrees. Image scale in the radial (horizontal) direction is about 7 kilometers (4.3 miles) per pixel / Bridgeman Images

PIX4625230: Tempete sur Saturn seen by the Cassini probe - Huge Storm on Saturn seen by Cassini spacecraft - Evolution of a huge tempete on Saturn seen by the Cassini probe from December 5, 2010 to August 12, 2011. This series of images from Nasa's Cassini spacecraft shows the development of the largest storm seen on the planet since 1990. These true - color and composite near - true - color views chronicle the storm from its start in late 2010 through mid - 2011, showing how the distinct head of the storm quickly grew large but eventually became engulfed by the storm's tail. The earliest image of the storm, taken Dec. 5, 2010, is in the top left of the panel. The storm appears only as a small, white cloud on the terminator between the day side and night side of the planet. The next view, in the top middle of the panel and taken Jan. 2, 2011, shows that the head quickly grew much larger and a tail began to trail a great distance eastward. Some of the clouds moved south and got caught up in a current that flows to the east (to the right) relative to the storm head. In the top right of the panel, this tail, which appears as slightly blue clouds south and now west (left) of the storm head, can be seen encountering the storm in the Feb. 25 image.The April 22 image, in the bottom left of the panel, is one of Cassini's last views of the storm when it still had a recognizable head. In this view, the tail is south of the head and is well established by this time.The May 18 view, in the bottom middle, shows only the storm's tail. The head still existed at this time, but it is beyond the horizon and out of the field of view here.Between the time of the May 18 image and the next image shown here (from Aug. 12), the head of the storm was engulfed by the part of the storm's tail that spread eastward at the same latitude as the head. The Aug. 12 image, in the bottom right, shows that the head has lost its distinct identity and is now just part of the jumble of the storm. Also visible in these / Bridgeman Images

PIX4625257: Saturn seen by the Cassini probe - Saturn northern hemisphere seen by Cassini spacecraft: Saturn seen by the Cassini probe on 25 April 2016. Cassini scanned across the planet and its rings on April 25, 2016, capturing three sets of red, green and blue images to cover this entire scene showing the planet and the main rings. The images were obtained using Cassini's wide-angle camera at a distance of approximately 1.9 million miles (3 million kilometers) from Saturn and at an elevation of about 30 degrees above the ring plane. The view looks toward the sunlit side of the rings from a Sun-saturn-spacecraft angle, or phase angle, of 55 degrees. / Bridgeman Images

PIX4625283: Saturn seen at equinox - Saturn during Equinox - Saturn seen by the Cassini probe on August 12, 2009, 1.25 days after the exact date of Saturn equinox. The images that make up this mosaic were obtained at a distance of 847,000 km from the planet. Several satellites are visible in this image: Janus (lower left), Epimethee (lower middle), Pandora (on the right of the image, outside the rings) and Atlas (on the right, inside the F ring). Seen from our planet, the view of Saturn's rings during equinox is extremely foreshortened and limited. But in orbit around Saturn, Cassini spacecraft had no such problems. From 20 degrees above the ring plane, Cassini's wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the sun's disk was exactly overhead at the planet's equator. The novel illumination geometry that accompanies equinox lowers the sun's angle to the ring plane, significantly darkens the rings, and causes out - of - plane structures to look anomalously bright and to cast shadows across the rings. These scenes are possible only during the few months before and after Saturn's equinox which occurs only once in about 15 Earth years. Also at equinox, the shadows of the planet's expansive rings are compressed into a single, narrow band cast onto the planet as seen in this mosaic. The images comprising the mosaic, taken over about eight hours, were extensively processed before being joined together. At this time so close to equinox, illumination of the rings by sunlight reflected off the planet vastly dominates any meager sunlight falling on the rings. Hence, the half of the rings on the left illuminated by planetshine is, before processing, much brighter than the half of the rings on the right. On the right, it is only the vertically extended parts of the rings that catch any substantial sunlight. With no enhancement, the rings woul / Bridgeman Images

PIX4625340: Titan, Saturn satellite seen by Cassini - Saturn's moon Titan as seen by Cassini spacecraft: Visible and infrared composite image of Titan taken by the Cassini probe on August 21, 2014. View of methane and ethane lakes lit by the Sun. - This near-infrared, color mosaic from Nasa's Cassini spacecraft shows the sun glinting off of Titan's north polar seas. - The sunglint, also called a specular reflection, is the bright area near the 11 o'clock position at upper left. This mirror-like reflection, known as the specular point, is in the south of Titan's largest sea, Kraken Mare, just north of an island archipelago separating two separate parts of the sea - This particular sunglint was so bright as to saturate the detector of Cassini's Visual and Infrared Mapping Spectrometer (VIMS) instrument, which captures the view. - The southern portion of Kraken Mare (the area surrounding the specular feature toward upper left) displays a “” bathtub ring”” - a bright margin of evaporate deposits - which indicates that the sea was larger at some point in the past and has become smaller due to evaporation. The deposits are material left behind after the methane & ethane liquid evaporates, somewhat akin to the saline crust on a salt flat / Bridgeman Images

The star SAO 152320, in the center of the image, illuminates this nebula located in the constellation Unicorn, about 4000 years old - light from Earth. Curtains of gas and dust dramatically open here to reveal the inner region of this starforming region. Unceremoniously named, bright star SAO 152320 shines with intense light in the center of this field. Clouds of gas glow strongly and dust shrinks quickly under its radiative prowess. This vista lies some 4,000 light years away towards the constellation of Monoceros. This is a portion of a much larger nebula called Gum 1 / Bridgeman Images

PIX4622497: Nebula IC 2220 in the Carene - A mass - loss star in IC 2220 - This nebula is illuminated by a giant red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. The bright, supergiant star at the centre of this nebula is known only by its catalog designation, HD 65750. The nebulosity around the star is the result of light reflected by dust surrounding it. The dust is thought to consist mainly of particles of silica condensed from material which the star is losing from its distended surface at a fairly steady rate. The rate of mass loss is much higher than in normal stars and is sufficient to produce the reflection nebula IC 2220. The stellar nature of the central object is revealed by the four diffraction spikes extending from it. These are artifacts due to structures within the telescope. The light from the star has also produced the annular halation ring (a photographic artefact) that ornaments the nebula. These features, real or otherwise, have provoked the name 'Toby Jug' for this nebula, after the ornamental English drinking vessel or beer mug / Bridgeman Images

PIX4622532: Nebula IC 2948 in Centaur - Bok's cells - A group of Bok globules in IC 2948 - View of a detail of nebula IC 2948 in the center Centaur on Bok's cells. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. The dark spots in the picture are not photographic defects but an unusual type of interstellar cloud known as a Bok globule. Bok globules, named after astronomer Bart Bok who studied them extensively, are small dark clouds made of gas and dust that are typically condensing to form a star or stars. These Bok globules are located at a distance of about 6000 light years near IC 2944 cluster in the emission nebula IC 2948 / Bridgeman Images

PIX4622594: Nebulae IC 2948 and 2944 in Centaur - The Running Chicken Nebula - Nebula IC 2948 is a vast nebula located about 6000 light years from Earth in the southern constellation of Centaur. It is associated with the cluster of stars IC 2944 near which Bok's blood cells are visible. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. This image from the Wide Field Imager on the MPG/ESO 2.2 - metre telescope shows the Running Chicken Nebula, a cloud of gas and newborn stars that lies around 6500 light - years away from us in the constellation of Centaurus (The Centaur). Officially called IC 2944, or the Lambda Centauri Nebula, its strange nickname comes from the bird - like shape of its brightest region. The star Lambda Centauri itself lies just outside the field of view / Bridgeman Images

PIX4622599: Nebula IC 2948 in Centaurus - Nebula IC 2948 and IC 2944 in Centaurus - Nebula IC 2948 is a vast nebula located about 6000 years from Earth in the southern constellation of Centaurus. It is associated with the cluster of stars IC 2944 near which Bok's blood cells are visible. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. Image obtained through 3 different filters that highlight oxygen (blue), hydrogen (green), and sulfur (red). Between the Southern Cross and the rich Carina region, on the southern border of Centaurus, is a large, almost featureless emission nebula, IC 2948, with a sprinkling of bright stars, Collinder 249. It is against this uniform, backdrop that we see a brighter region (IC 2944) which hosts small group of dark clouds of the kind known as 'Bok globules'. They are named for the Dutch - American astronomer who first drew attention to them as the possible sites of star formation. There are young stars scattered through the nebula and these stars are responsible for its existence. The stars only 10 million years old and the hydrogen they illuminate seems to be unusually thinly spread and very uniform, so the nebula is both faint and extensive. It is also quite distant, about 6000 light years and is only two degrees from the Galactic plane, so there are many foreground stars. This image is in the classic “” Hubble palette”” where SII is assigned to red, H - alpha to green, and OIII to blue. RGB frames were taken for star colors / Bridgeman Images

PIX4622673: Nebula IC 4628 in Scorpio - Nebula IC 4628 in Scorpius - Nebula has a low light emission, IC 4628 (or Gum 56) is alongside the open cluster Collinder 316, which houses many young hot stars. Image obtained through 3 different filters that highlight oxygen (blue), hydrogen (green), and sulfur (red). This beautiful, arc - like rim of nebulosity is in the far southern sky, out of sight from most of the USA and Europe. It is quite faint and has often been overlooked because of it, even by southern observers. However, it is in a rich region in Scorpius. This richness is reflected in the number of names associated with the objects in the field illustrated here. There is a large scattered star cluster, Collinder 316 which extends over most of the picture. It encloses Trumpler 24, more or less the same cluster under another name, and all of this is part of the Sco OB1 association, a much larger gathering of very hot, intrinsically luminous stars in this part of the sky. The nebula itself is also known as Gum 56, after the Australian Colin Gum who catalogued emission nebulae in the southern sky using wide field photography. This image is in the classic “” Hubble palette”” where SII is assigned to red, H - alpha to green, and OIII to blue. RGB frames were taken for star colors / Bridgeman Images
