PIX4627010: Le Soleil vu en ultraviolet by SOHO on 18/11/2009 - The Sun seen in ultraviolet by Soho. November 18, 2009 - A protuberance, a plasma cloud, escapes from the Sun. White areas are the hottest and most active areas. Prominences are cooler clouds of gases suspended above the Sun by magnetic forces / Bridgeman Images
PIX4627117: The Sun seen in ultraviolet by STEREO on 04 - 12 - 2006 - First observations of the Sun by the first of the two satellites of the STEREO mission (Solar Terrestrial Relations Observatory), on 4 December 2006. These false-coloured ultraviolet images show the Sun at different temperatures / Bridgeman Images
PIX4626477: Remains of supernova located about 1400 light years ago in the constellation Swan. The supernova would have exploded less than 10,000 years ago. Image obtained by the Oschin telescope of Mount Palomar through several filters and composed - The Veil Nebula, also known as the Cygnus Loop, is a large supernova remnant, relatively faint supernova remnant in the constellation Cygnus. The source supernova exploded some 5000 to 8000 years ago. The distance to the nebula is not precisely known, with estimates ranging from 1400 to 2600 light years. It was discovered on 1784 September 5 by William Herschel. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory.: Les laces du Swan - The Veil nebula / Bridgeman Images
LRI4626381: South view of the Dome of the Hotel des Invalides realized by Jules Hardouin Mansart (1646-1708) on a project by Liberal Bruand. 1679-1708 Paris - The Dome of the Hotel des Invalides, built in 1679-1708 by Hardouin Jules Mansart (1646-1708).

LRI4626822: Gothic art: view of the papal altar above the Tabernacle made by Giovanni di Stefano around 1367 adorns twelve panels decorated with frescoes by Barna da Siena (14th century). 1367-1368. Basilica of St. John of Laterano (San Giovanni in Laterano), 1562-1567. Rome, Italian School, (14th century) / Bridgeman Images
LBY4626098: The bridge of Bir Hakeim (Bir-Hakeim) in Paris. Ex Passy Viaduct, it became in 1949, the bridge of Bir Hakeim. One of the most beautiful works of metallic architecture. The 237-meter bridge has the particularity of being at the same time, metropolitan, automobile and pedestrian. Architects Louis Biette (1860-1939) and Jean Camille Formige (1845-1926), construction 1903-1905. / Bridgeman Images
PIX4626117: Titan Exploration - Illustration - Exploring a hydrocarbon swamp on Titan - Automatic balloons fly over an oil marsh on the surface of Titan. A pair of balloon - borne probes leisurely survey a methane - ethane “” swamp”” on Titan. Each probe carries its own spot light illuminating the terrain below, augmenting the haze - filtered sunlight. Scientists have long speculated that methane and ethane may exist as liquids on Titan's extremely cold surface, but it wasn't until 2005 that the Cassini spacecraft's radar imager detected what indeed may be large hydrocarbon lakes on Titan's northern latitudes. While it is believed that the liquid in these lakes would be primarily methane and ethane, this won't be confirmed until the lakes - - if that's indeed what they are - - are actually sampled. Whatever lies on Titan's surface, there is the possibility that the ancient and exotic environment has given rise to compounds heretofore unknown on Earth. Large quantities of Methane and ethane exist in Earth's relatively warm environment as components of natural gas / Bridgeman Images
PIX4627176: Le Soleil vu by SDO on December 6, 2010 - The Sun seen by SDO. December 6, 2010 - Le Soleil vu en ultraviolet by SDO (Solar Dynamics Observatory) on December 6, 2010. It shows a gas filament of nearly a million miles breaking. A very long solar filament that had been snaking around the Sun erupted on December 6, 2010 with a flourish. Nasa's Solar Dynamics Observatory (SDO) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long ((about half a solar radius) and a prominent feature on the Sun visible over two weeks ago before it rotated out of view. Filaments are elongated clouds of cooler gases suspended above the Sun by magnetic forces. They are rather unstable and often break away from the Sun / Bridgeman Images
