MDA4628859: The Promenade planted on the Viaduc des Arts, Paris 12th arrondissement. In 1990, the former viaduct of Paris was renovated by Patrick Berger. Built in 1859, it connected the Bastille by rail to Vincennes. The construction of Opera Bastille will lead to the reabilitation of the viaduct, built by the Paris City Hall. The planted promenade was designed by Philippe Mathieux., Denance, Michel / Bridgeman Images

PIX4626096: Oil Lake on Titan - Titan's ethane ocean - Artist's view of a hydrocarbon lake (methane - ethane) on the surface of Titan. Compared to the Earth, Titan is very far from the Sun's warming rays - - about ten times further - - and this leaves Titan a very cold world. Titan has an average surface temperature of minus 290o F. If there is any water on Titan it is frozen hard as steel, yet Titan may be the only body in the Solar System besides the Earth that harbors a liquid ocean. Titan's ocean would not be one of water, rather it would probably be composed of (very cold) liquid ethane. (On the Earth we know ethane as a colorless, odorless, nontoxic, flammable gas, a constituent of natural gas and petroleum.) If this werenn't exotic enough, immediately beneath this ocean may lie hundreds of feet of frozen acetylene (a common component of welder's torches) / Bridgeman Images
PIX4626110: Oil Marsh on Titan - Ethane swamp on Titan - Artist's view of an ethane marsh on the surface of Titan. Initially astronomers thought that Titan's entire surface may be covered by a liquid hydrocarbon ocean. More recent observations in infrared wavelengths suggest otherwise. In this image the artist is suggesting that Titan may be host to extremely cold ethane - methane swamps / Bridgeman Images
PIX4626099: Snow Tempete on Titan - Illustration - Snow squall on Titan - An ethane snowstorm immobilizes astronauts exploring Titan's surface. A forbidding ethane snow squall immobilizes two explorers and their surface transportation. While there's been no evidence yet for the presence of snow on Titan, in September 2006 the Cassini orbiter detected what appears to be a massive ethane cloud surrounding Titan's north pole. This cloud may be snowing extremely cold - - near minus 300* F - - ethane snowflakes onto the surface below / Bridgeman Images
PIX4629063: Sunset - September Equinox - Sunset - September equinox - At the September equinox (the 22nd or 23rd depending on the years), the Sun passes from north to south of the equator line on the Celestial vault. Day and night have the same duration, the Sun rises precisely to the east and it really sets to the west. Sunset on september equinox, where the sun is setting exactly toward the west / Bridgeman Images
MDA4628860: Viaduc des Arts in Paris 75012. In 1990, the old viaduct of Paris was renovated by Patrick Berger. Built in 1859, it connected the Bastille by rail to Vincennes. The construction of the Opera Bastille will lead to the rehabilitation of the viaduct, rachete a al SNCF by the City Hall of Paris. The vaults desormais restaurees are home to artisans of art and creation., Denance, Michel / Bridgeman Images
