NASA Astronomy Picture of the Day:

What kind of strange galaxy is this? This rare structure is known as a polar ring galaxy, and it seems to have two different rings of stars. In this galaxy, NGC 660, one ring of bright stars, gas, and dark dust appears nearly vertical, while another similar but shorter ring runs diagonally from the upper left. How polar ring galaxies obtain their striking appearance remains a topic of research, but a leading theory holds that it is usually the result of two galaxies with different central ring planes colliding. NGC 660 spans about 50,000 light years and is located about 40 million light years away toward the constellation of the Fish (Pisces). The featured image was captured recently from Observatorio El Sauce in Chile.

What excites the Heart Nebula? First, the large emission nebula on the upper left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by sulfur (yellow) and oxygen (blue). In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their atom-exciting energetic light and winds. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. This wide field image shows much more, though, including the Fishhead Nebula just below the Heart, a supernova remnant on the lower left, and three planetary nebulas on the image right. Taken over 57 nights, this image is so deep, though, that it clearly shows fainter long and complex filaments.

George Santayana - (1863 – 1952) ~ Jorge Agustín Nicolás Ruiz de Santayana y Borrás, was a philosopher, essayist, poet, critic and novelist. Born in Spain and raised and educated in the US from the age of eight. He left his position at Harvard at the age of 48 and returned to Europe permanently. Santayana was the author of many books and is popularly known for his aphorisms. He was profoundly influenced by Spinoza's life and thought. Although he was an atheist, he treasured the Spanish Catholic values, practices, and worldview in which he was raised.

NASA Astronomy Picture of the Day:

This kilometer high cliff occurs on the surface of a comet. It was discovered on the dark nucleus of Comet Churyumov - Gerasimenko (CG) by Rosetta, a robotic spacecraft launched by ESA, which orbited the comet from 2014 to 2016. The ragged cliff, as featured here, was imaged by Rosetta early in its mission. Although towering about one kilometer high, the low surface gravity of Comet CG would likely make a jump from the cliffs by a human survivable. At the foot of the cliffs is relatively smooth terrain dotted with boulders as large as 20 meters across. Data from Rosetta indicates that the ice in Comet CG has a significantly different deuterium fraction -- and hence likely a different origin -- than the water in Earth's oceans. The probe was named after the Rosetta Stone, a rock slab featuring the same text written in three different languages that helped humanity decipher ancient Egyptian writing.

Eduardo Hughes Galeano, (1940 - 2015) was an Uruguayan journalist, writer, poet and novelist. Among his many books, Galiano's best-known works are "Las venas abiertas de América Latina" (Open Veins of Latin America, 1971) and ""Memoria del fuego" (Memory of Fire Trilogy - 1982–6). "I'm a writer," the author once said of himself, "I am obsessed with remembering, with remembering the past of America and above all that of Latin America, intimate land condemned to amnesia. His first or paternal surname is Hughes and the second or maternal family name is Galeano. His two family names were inherited from Welsh and Italian great-grandfathers; the other two were from Germany and Spain. Galeano wrote under his maternal family name.
