NASA Astronomy Picture of the Day:

What unexpected things do you see when you look up at the night sky? Today’s image resembles an abstract painting, with large swaths of color strewn across a cosmic canvas seemingly without design. Despite the image's abstract nature, the human mind finds patterns, identifying a large claw reaching up towards a floating bubble. Embedded within these seemingly random structures are the physical laws that govern how light and matter interact. The Claw (Sh2-157) and Bubble (NGC 7635) Nebulae glow colors that are mapped to the yellow and blue shown, indicating the presence of hydrogen and oxygen ionized by the intense light emitted from stars several times the mass of the Sun. This image depicts both the chaos and structure of astronomical processes, showing that a common thread between art and science is to look for the unexpected.

Basilica of Santa Francesca, Rome, Italy. A church at the site was known by the tenth century. It was named Santa Maria Nova ("New St Mary"), to distinguish it from the other church inside the Roman forum devoted to St Mary, Santa Maria Antiqua ("Ancient St Mary"), which had fallen into ruin by then. The relics from the ancient church were moved to this church under Pope Leo. Santa Maria Nuova was enlarged in the second half of the tenth century, and then rebuilt by Pope Honorius III in the thirteenth century, adding the campanile and the apse, as well as being decorated with a mosaic Maestà, a depiction of the Madonna enthroned accompanied by saints (as seen in the picture). Since 1352 the church has been in the care of the Olivetans. In the 16th century, the church was rededicated to Frances of Rome (Francesca Buzzi), who was canonized in 1608 and whose relics are in the crypt. The interior of the church has undergone many refurbishments.

NASA Astronomy Picture of the Day:

Titania's tortured terrain is a mix of canyons, cliffs, and craters. NASA's interplanetary robot spacecraft Voyager 2 passed the largest moon of Uranus in 1986 and took the feature picture. That the trenches of Titania resemble those on another moon of Uranus, Ariel, indicate that Titania underwent some violent surface event possibly related to water freezing and expanding in its distant past. Although Titania is Uranus's largest moon, it is only about half the radius of Triton - the largest moon of Uranus's sister planet Neptune, which itself is slightly smaller than Earth's Moon. Titania, discovered by William Herschel in 1787, is essentially a large dirty iceball that is composed of about half water-ice and half rock. There is recent speculation that radioactive heating melts some underground ice into oceans.

Pablo Picasso (1881 –1973) - Spanish painter, sculptor, printmaker, ceramicist and theatre designer. He spent most of his adult life in France. Regarded as one of the most influential artists of the 20th century, he us known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage art and for the wide variety of styles he helped develop and explore. Picasso demonstrated extraordinary artistic talent in his early years and was extremely prolific throughout his life with over 20,000 paintings, drawings, sculptures, ceramics and other items such as costumes and theater sets. Read more

NASA Astronomy Picture of the Day:

What's happened to the center of this galaxy? Dramatic dust lanes run across the center of unusual elliptical galaxy Centaurus A. These dust lanes are so thick they almost completely obscure the galaxy's center in visible light. This is particularly unusual as Cen A's older stars and oval shape are characteristic of a giant elliptical galaxy, a galaxy type typically low in dark dust. Pictured in this deep image is a complex network of foreground gas and dust, as well as shells of dim stars and a jet projecting to the upper right. Also known as NGC 5128, Cen A is surely the result of a galactic collision where many young dust-creating stars were formed. However, details of the creation of Cen A's unusually active center and iconic central dust lanes are still being researched. Cen A lies only 13 million light years away, making it the closest active galaxy. Jigsaw Galaxy: Astronomy Puzzle of the Day

Sand dunes of the Thar Desert in the Indian state of Rajasthan. On this day in 1949, the state was formed after a merger of several Rajput princely states into the Indian Union following India's independence from British colonial rule.
