    examine every photo of earth taken from 'space'. Notice they are either paintings or computer images .

    here is one painting of Saturn by NASA created in the 70s lol

    [​IMG]

    Real NASA caption:

    13 million miles away? That's impressive lensmanship! And, done with 1977 technology too! The same year that the Apple II computer was introduced ...

    [​IMG]

    Also the same year as the 1977 Firebird

    [​IMG]

    And, Rod Stewart had the #1 hit song:

    [​IMG]

    ... I'm impressed!

    The Voyager spacecraft were launched in 1977 and are still out there at the edge of our solar system, says NASA, so this 13-million mile photo was taken with 1970s era technology and then beamed back to Earth via NASA's incredible radio communications system over a distance of millions of miles. And, of course, no stars are visible even though the faintly illuminated specks of Saturn's moons from 13 million miles away are quite visible in the photo.

    I'm not sure why this photo was included in an article about the Cassini Mission since it is part of the much earlier Voyager hoax mission ... but there you go.

    But, there is something strange here. If I load the above image into my old Photoshop 7 and merely bring up the levels (make it uniformly brighter) so we can peer into the darkness of space, I get this:

    Lennon crater was recently named to honor English musician/singer/songwriter John Lennon (1940-1980). This image was acquired as part of MDIS's high-resolution stereo imaging campaign. Images from the stereo imaging campaign are used in combination with the surface morphology base map or the albedo base map to create high-resolution stereo views of Mercury's surface, with an average resolution of 200 meters/pixel. Viewing the surface under the same Sun illumination conditions but from two or more viewing angles enables information about the small-scale topography of Mercury's surface to be obtained.

    The HiRISE instrument would make a great backyard telescope for viewing Mars, and we can also use it at Mars to view other planets, such as Jupiter. This is an image of Earth and the Moon, acquired at 5:20 a.m. MST on 3 October 2007, at a range of 142 million kilometers, which gives the HiRISE image a scale of 142 km/pixel and an Earth diameter of about 90 pixels and a Moon diameter of 24 pixels. The phase angle is 98 degrees, which means that less than half of the disks of the Earth and Moon have direct illumination. We could image Earth/Moon at full disk illumination only when they are on the opposite side of the sun from Mars, but then the range would be much greater and the image would show less detail.

    On the day this image was taken, the Japanese Kayuga (Selene) spacecraft was en route from the Earth to the Moon, and has since returned spectacular images and movies. On the Earth image we can make out the west coast outline of South America at lower right, although the clouds are the dominant features. These clouds are so bright, compared with the Moon, that they are saturated in the HiRISE images. In fact, the RED-filter image was almost completely saturated, the blue-green image had significant saturation, and the brightest clouds were saturated in the IR image. This color image required a fair amount of processing to make a nice-looking release. The Moon image is unsaturated but brightened relative to Earth for this composite. The lunar images are useful for calibration of the camera.

    The left-front wheel of NASA's Curiosity Mars rover shows dents and holes in this image taken during the 469th Martian day, or sol, of the rover's work on Mars (Nov. 30, 2013). The image was taken by the Mars Hand Lens Imager (MAHLI) camera, which is mounted at the end of Curiosity's robotic arm. By that sol, Curiosity had driven 2.78 miles (4.47 kilometers). An uptick in the pace of wear and tear on the rover's wheels in the preceding few weeks appears to be correlated with driving over rougher terrain than during earlier months of the mission. Routes to future destinations for the mission may be charted to lessen the amount of travel over such rough terrain.

    The effects of the small moon Prometheus loom large on two of Saturn's rings in this image taken a short time before Saturn's August 2009 equinox. A long, thin shadow cast by the moon stretches across the A ring on the right. The gravity of potato-shaped Prometheus (86 km, or 53 miles across) periodically creates streamer-channels in the F ring, and the moon's handiwork can seen be on the left of the image. To learn more and to watch a movie of this process, see PIA08397.

    The novel illumination geometry that accompanies equinox lowers the sun's angle to the ringplane, significantly darkens the rings, and causes out-of-plane structures to look anomalously bright and 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. Before and after equinox, Cassini's cameras have spotted not only the predictable shadows of some of Saturn's moons, but also the shadows of newly revealed vertical structures in the rings themselves.

    Prometheus is overexposed in this image. Bright specks in the image are background stars. This view looks toward the northern, unilluminated side of the rings from about 28 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on 30 July 2009. The view was acquired at a distance of approximately 1.8 million km (1.1 million miles) from Saturn and at a sun-Saturn-spacecraft, or phase, angle of 97 degrees. Image scale is 10 km (6 miles) per pixel.

    This image covers a portion of Eberswalde Crater on Mars, revealing a possible delta-lake transition. Water flowed into the crater through a series of tributary channels to the west of the crater and after the water entered, it formed a distributive network and partly filled the crater to form a lake (Eberswalde Crater is approximately 70 kilometers wide and 1.2 kilometers deep).

    The bright layers are part of the terminal scarp at the eastern edge of the delta. Some of the steeper slopes visible at the edge of the fan may be coarser-grained resistant channel ridges. The CRISM instrument on board the Mars Reconnaissance Orbiter has detected phyllosilicates (clays) in the bright layers. One of the ways clays form on Earth is when water erodes rock and makes fine particles which settle out of water; this often occurs in river deltas and lake beds. The delta in Eberswalde Crater and the detection of phyllosilicates provides evidence for possible persistent aqueous activity on Mars.

    Three nanosatellites, known as Cubesats, are deployed from a Small Satellite Orbital Deployer (SSOD) attached to the Kibo laboratory’s robotic arm at 7:10 a.m. (EST) on Nov. 19, 2013. Japan Aerospace Exploration Agency astronaut Koichi Wakata, Expedition 38 flight engineer, monitored the satellite deployment while operating the Japanese robotic arm from inside Kibo. The Cubesats were delivered to the International Space Station Aug. 9, aboard Japan’s fourth H-II Transfer Vehicle, Kounotori-4.

    Having operated at Mars for more than seven years, MRO and the HiRISE camera continue to make new discoveries. One of these is that many sand dunes and ripples are moving, some at rates of several meters per year.

    In this observation, a dune field in a Southern hemisphere crater was observed approximately one Mars year apart, first on 2 September 2011 and then again on 11 July 2013 (a year on Mars is 687 Earth days). By taking images at the same time of year, solar illumination angles are the same, so that subtle apparent changes can be linked to true displacement on the surface and not artifacts.

    In these two images, there is little distortion (a digital elevation model would remove more distortion). Here, we focus on the southern and northern part of two adjacent dunes. With an animated image, the displacement of ripples on the dunes relative to nearby rocks and dark ripples are clearly visible. It seems that the ripples on the southern dune are moving northeast, while those on the northern dune are moving west, indicating complex winds in this area. The static dark ripples may be composed of larger grains than those in the dunes and are therefore harder to move. In most areas of Mars, darker-toned ripples are more mobile than lighter ones. This area is different, demonstrating that continued imaging of the Martian surface results in new findings and revisions of ideas.

    Saturn's moon Enceladus reflects sunlight brightly while the planet and its rings fill the background of this Cassini view. Enceladus is one of the most reflective bodies in the solar system because it is constantly coated by fresh, white ice particles.

    This view looks toward the anti-Saturn side of Enceladus (504 kilometers, or 313 miles across). North on Enceladus is up and rotated 21 degrees to the left. This view looks toward the northern, sunlit side of the rings from just above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 21, 2010. The view was obtained at a distance of approximately 102,000 kilometers (63,000 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 16 degrees. Image scale is 612 meters (2,008 feet) per pixel.

    Water On Ceres
    Astronomers have discovered direct evidence of water on the dwarf planet Ceres in the form of vapor plumes erupting into space, possibly from volcano-like ice geysers on its surface.
    Using European Space Agency's Herschel Space Observatory, scientists detected water vapor escaping from two regions on Ceres, a dwarf planet that is also the largest asteroid in the solar system. The water is likely erupting from icy volcanoes or sublimation of ice into clouds of vapor.
    "This is the first clear-cut detection of water on Ceres and in the asteroid belt in general," said Michael Küppers of the European Space Agency, Villanueva de la Cañada, Spain, leader of the study detailed today (Jan. 22) in the journal Nature.

    The research has implications for how Ceres formed, and supports models that suggest the planets moved around a lot within the solar system during its formation, Küppers told SPACE.com.
    Ceres, a dwarf planet or giant asteroid (depending on the definition used), is the largest object in the asteroid belt, orbiting at 2.8 astronomical units (the distance from Earth to the sun). The "snowline" is thought to partition the solar system into dry objects inside the asteroid belt, and icy objects such as comets further out. But the finding of water on Ceres suggests more mixing has occurred.
    Scientists have suspected that there is a substantial amount of water on Ceresfor about 30 years. A study found hints of water in the form of hydroxide, a product of water's dissociation, on Ceres in 1991, but the finding wasn't confirmed by later observations. Now, Küppers and his colleagues have confirmed the finding.

    The researchers used the Herschel Space Observatory's spectrometer to look for signals of water. Clouds of water vapor around Ceres absorbed the heat that radiates from the dwarf planet, which Herschel's instrument detected. The team found that Ceres produces about 2×10^26 molecules, or 13 lbs. (6 kilograms), of water vapor per second from its surface.
    One possible source of the water is icy volcanism. "It is like volcanism in that hot material from the interior is 'spat out' to the surface," Küppers said — much like a geyser. But these icy volcanoes eject water vapor instead of molten rock, he said.

    Another possibility is that ice near the surface of Ceres sublimes, or goes directly from a solid to a gas, dragging with it dust from the surface and exposing more ice. A similar process occurs on comets.

    "I personally consider cometary-style sublimation the most likely source, because I find it difficult to maintain the internal heat over the age of the solar system to maintain volcanoes," Küppers said, but he added that more studies were needed.

    Dawn spacecraft, set to go into orbit around Ceres in early 2015, could answer some questions about the water on Ceres. Dawn recently visited the asteroid Vesta, a baked world whose surface is covered with volcanic eruptions.

    "One of the most puzzling questions about the origin and evolution of asteroids is why Vesta and Ceres are so different," astrophysicists Humberto Campins and Christine Comfort at the University of Central Florida in Orlando wrote in an article in the same issue of Nature.

    Water vapor can transport a lot of heat, so when Ceres formed 4.6 billion years ago, sublimation of water ice might have dissipated much of its heat into space, Campins and Comfort wrote. "This would have stopped Ceres from ending up with an igneous surface like that of Vesta."

    Detecting water on Ceres supports models of the solar system in which giant planets, such as Jupiter, migrated to their current positions, mixing material from the outer and inner regions of the solar system. This mixing could have moved Ceres and Vesta far from the sites where they formed. Ceres probably formed close to its current position, but accreted material from further out, Küppers said.

    The findings also suggest that asteroids may have delivered some of the water in Earth's oceans.

    From end to end, the newly discovered gamma-ray bubbles extend 50,000 light-years, or roughly half of the Milky Way's diameter, as shown in this illustration. Hints of the bubbles' edges were first observed in X-rays (blue) by ROSAT, a Germany-led mission operating in the 1990s. The gamma rays mapped by Fermi (magenta) extend much farther from the galaxy's plane. Credit: NASA's Goddard Space Flight Center

    Extreme Power of Black Hole Revealed
    Astronomers have used NASA's Chandra X-ray Observatory and a suite of other telescopes to reveal one of the most powerful black holes known. The black hole has created enormous structures in the hot gas surrounding it and prevented trillions of stars from forming.

    The black hole is in a galaxy cluster named RX J1532.9+3021 (RX J1532 for short), located about 3.9 billion light years from Earth. The image here is a composite of X-ray data from Chandra revealing hot gas in the cluster in purple and optical data from the Hubble Space Telescope showing galaxies in yellow. The cluster is very bright in X-rays implying that it is extremely massive, with a mass about a quadrillion - a thousand trillion - times that of the sun. At the center of the cluster is a large elliptical galaxy containing the supermassive black hole.

    The large amount of hot gas near the center of the cluster presents a puzzle. Hot gas glowing with X-rays should cool, and the dense gas in the center of the cluster should cool the fastest. The pressure in this cool central gas is then expected to drop, causing gas further out to sink in towards the galaxy, forming trillions of stars along the way. However, astronomers have found no such evidence for this burst of stars forming at the center of this cluster.

    This problem has been noted in many galaxy clusters but RX J1532 is an extreme case, where the cooling of gas should be especially dramatic because of the high density of gas near the center. Out of the thousands of clusters known to date, less than a dozen are as extreme as RX J1532. The Phoenix Cluster is the most extreme, where, conversely, large numbers of stars have been observed to be forming.

    What is stopping large numbers of stars from forming in RX J1532? Images from the Chandra X-ray Observatory and the NSF's Karl G. Jansky Very Large Array (VLA) have provided an answer to this question. The X-ray image shows two large cavities in the hot gas on either side of the central galaxy. The Chandra image has been specially processed to emphasize the cavities. Both cavities are aligned with jets seen in radio images from the VLA. The location of the supermassive black hole between the cavities is strong evidence that the supersonic jets generated by the black hole have drilled into the hot gas and pushed it aside, forming the cavities.

    Shock fronts - akin to sonic booms - caused by the expanding cavities and the release of energy by sound waves reverberating through the hot gas provide a source of heat that prevents most of the gas from cooling and forming new stars.

    The cavities are each about 100,000 light years across, roughly equal to the width of the Milky Way galaxy. The power needed to generate them is among the largest known in galaxy clusters. For example, the power is almost 10 times greater than required to create the well-known cavities in Perseus.

    Although the energy to power the jets must have been generated by matter falling toward the black hole, no X-ray emission has been detected from infalling material. This result can be explained if the black hole is "ultramassive" rather than supermassive, with a mass more than 10 billion times that of the sun. Such a black hole should be able to produce powerful jets without consuming large amounts of mass, resulting in very little radiation from material falling inwards.

    Another possible explanation is that the black hole has a mass only about a billion times that of the sun but is spinning extremely rapidly. Such a black hole can produce more powerful jets than a slowly spinning black hole when consuming the same amount of matter. In both explanations the black hole is extremely massive.

    A more distant cavity is also seen at a different angle with respect to the jets, along a north-south direction. This cavity is likely to have been produced by a jet from a much older outburst from the black hole. This raises the question of why this cavity is no longer aligned with the jets. There are two possible explanations. Either large-scale motion of the gas in the cluster has pushed it to the side or the black hole is precessing, that is, wobbling like a spinning top.

    A paper describing this work was published in the November 10th, 2013 issue of The Astrophysical Journal and is available online. The first author is Julie Hlavacek-Larrondo from Stanford University. The Hubble data used in this analysis were from the Cluster Lensing and Supernova survey, led by Marc Postman from Space Telescope Science Institute.

    NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory in Cambridge, Mass., controls Chandra's science and flight operations.
