Montmartre

Postcard FR-446497 from France shows Montmartre, a 130-meter-tall hill in the north of Paris, France. It is known for the white-domed Basilica of the Sacré Cœur on its summit. The ancient Romans had referred the site as Mount Mercury in the 8th century, and Mount Mars in the 9th century. Saint Denis, a Christian bishop, was decapitated on the hilltop in 250 AD for preaching the Christian faith. The hill was named Mountain of the Martyr to commemorate the martyrdom of Saint Denis.

Many artists had set up studios or shops in or around Montmartre, including Salvador Dalí, Amedeo Modigliani, Claude Monet, Piet Mondrian, Pablo Picasso, Camille Pissarro and Vincent van Gogh.

Now Montmartre is also know as a nightclub district with vibrant nightlife.

Blood Moon in Sky

Postcard US-1651277 to Russia shows various nightlife in Florida under a "blood moon".

In the early morning of April 15, 2014 when a total lunar eclipse occurred, the "blood moon" was visible from most of North and South America, Hawaii and parts of Alaska. A total lunar eclipse occurs when the moon, the earth, and the sun are in alignment. As a result, the moon is completely covered by the Earth’s shadow. The following photo shows the total eclipse of the moon underway over Las Vegas, Nevada as seen from West Sahara Avenue and South Valley View Boulevard around 12:40 am on April 15, 2014. The bright star on the lower-right corner is Spica from the constellation Virgo, the 15th brightest star in the sky.

The eclipse was the first of four consecutive total lunar eclipses, known as a tetrad, on April, 15, 2014, October 8, 2014, April 4, 2015, and September 28 2015.
