PIX4625061: Saturn rings seen in ultraviolet by Cassini - Saturn's rings in utraviolet - Saturn rings seen in ultraviolet by the Cassini probe. The colours indicate a different distribution of the material within the rings. This false - color image of Saturn's main rings was made by combining data from multiple star occultations using the Cassini ultraviolet imaging spectrograph. During occultations, scientists observe the brightness of a star as the rings pass in front of the star. This provides a measurement of the amount of ring material between the spacecraft and the star. Cassini has given scientists the most detailed view yet of Saturn's densely packed B ring. Cassini found that this part of the rings is densely packed with clumps, called self - gravity wakes, separated by almost empty gaps. These clumps in Saturn's B ring are neatly organized and constantly colliding, which surprised scientists. The clumps in Saturn's B ring, 30 to 50 meters (100 to 160 feet) across, are too small to be seen directly. However, scientists can map the distribution, shape and orientation of the clumps. Colors in this image indicate the orientation of clumps, and brightness indicates the density of ring particles. The formation of wakes is strongest in the bluer regions, where ring particles clump together in tilted wakes. Particles in the central yellow regions are too densely packed for any starlight to pass through. The ultraviolet imaging spectrograph measured the flickering of the star Alpha Arae as it passed by the rings Nov. 9 and 10, 2006 / Bridgeman Images

PIX4624995: Saturn rings C - B by Cassini - false colors - Image in fake colors made by the Cassini probe on June 30, 2004. The different colors correspond to differences in the chemical composition of the particles that make up the rings. The ring system is composed from the closest to Saturn to the outermost by ring D, then C, B, the division of Cassini, A with the division of Encke, F, G and E. Here are the variations in the composition of rings C and B that are watched. Turquoise blue corresponds to particles composed of pure ice; in red, dirty and finer ice particles. / 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

PIX4623608: Planetary nebula Helix (NGC 7293) in Aquarius - Planetary nebula Helix (NGC 7293) - This nebula is located 690 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope This faint object is the nearest planetary nebula to the Sun and on deep photographs has a diameter of about half a degree - - the same apparent size as the Sun in the sky. The AAT colour picture shows the brighter parts of the nebula, revealing various ionization levels within the shell of matter ejected from the central star. This picture was made without unsharp masking. Unsharp masking emphasises the smallest of the radial blobs inside the red shell, which are about 150 astronomical units across (150 times the Earth - Sun distance). These radial streaks give this beautiful object its alternative name, the Sunflower Nebula. The Helix is about 400 light years away, or about 100 times more distant than the nearest stars / Bridgeman Images
PIX4623677: Planetary nebula IC 418 dans le Lievre/HST - IC 418: The “” Spirograph” Nebula Glowing like a multi - faceted jewel, the planetary nebula IC 418 lies about 2,000 light - years from Earth in the direction of the constellation Lepus. This photograph is from Nasa's Hubble Space Telescope, obtained with the Wide Field Planetary Camera 2. A planetary nebula represents the final stage in the evolution of a star similar to our Sun. The star at the center of IC 418 was a red giant a few thousand years ago, but then ejected its outer layers into space to form the nebula, which has now expanded to a diameter of about 0.1 light - year. The stellar remnant at the center is the hot core of the red giant, from which ultraviolet radiation floods out into the surrounding gas, causing it to fluoresce. Over the next several thousand years, the nebula will gradually disperse into space, and then the star will cool and fade away for billions of years as a white dwarf. Our own Sun is expected to undergo a similar fate, but fortunately this will not occur until some 5 billion years from now. The Hubble image of IC 418 is shown in a false - color representation, based on Wide Field Planetary Camera 2 exposures taken in February and September, 1999 through filters that isolate light from various chemical elements. Red shows emission from ionized nitrogen (the coolest gas in the nebula, located furthest from the hot nucleus), green shows emission from hydrogen, and blue traces the emission from ionized oxygen (the hottest gas, closest to the central star) / Bridgeman Images
TEC4623973: The Palais de Tokyo from New York Avenue in Paris. Architects: Andre Aubert, Paul Viard, Jean Claude Dondel and Marcel Dastugue, 1937. Built for the 1937 World Exhibition, the International Exhibition of Arts and Techniques in the Modern City. The Palais de Tokyo is a small part of the Luxembourg Museum and the Peure Palais too narrow to accommodate municipal collections. It owes its name to the Tokyo wharf, now New York Avenue. / Bridgeman Images
TEC4623978: The Musee Galliera, 14 avenue du President Wilson, Paris 16th. Construction 1878-1894. Architect Leon Ginain (1825-1898). In order to give the City of Paris her art collections, the Duchess of Galliera built a museum in 1894, a pastiche of the Italian Renaissance. But for political reasons, it is the city of Genes (Italy) that houses the guilt and paintings while Paris remains the owner of this museum. / Bridgeman Images

TEC4624184: Palais de Chaillot in Paris in the 16th arrondissement, completed in 1937, architects Leon Azema (1888-1978), Louis Hippolyte Boileau (1878-1948), Jacques Carlu (1890-1976). The inscriptions are by Paul Valery (1871-1845) “It depends on the passing man whether I am fallen or treasor, whether I speak or remain silent. This is up to you, friend does not enter without desperation.”” / Bridgeman Images
