APOD: 2023-10-31 - Halloween and the Wizard Nebula (Narrated by Amy)
Astronomy Picture of the Day - October 31st, 2023 - Halloween and the Wizard Nebula (Narrated by Amy)
Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere). With a modern calendar however, even though Halloween occurs today, the real cross-quarter day will occur next week. Another cross-quarter day is Groundhog Day. Halloween's modern celebration retains historic roots in dressing to scare away the spirits of the dead. Perhaps a fitting tribute to this ancient holiday is this closeup view of the Wizard Nebula (NGC 7380). Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional ancient sorcerer. Although the nebula may last only a few million years, some of the stars being conjured from the gas by the great gravitational powers may outlive our Sun.
Astronomy Picture of the Day - January 22nd, 2023 - In Green Company: Aurora over Norway (Narrated by Brian)
Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the creative featured image was captured as a composite from three separate exposures. The setting is a summit of the Austnesfjorden fjord close to the town of Svolvear on the Lofoten islands in northern Norway. The time was early 2014. Although our Sun passed the solar minimum of its 11-year cycle only a few years ago, surface activity is picking up and already triggering more spectacular auroras here on Earth.

Wikipedia Picture of the Day - December 25th, 2020 - Pope Pius VI (Narrated by Brian)
Pope Pius VI (25 December 1717 – 29 August 1799) was the head of the Roman Catholic Church and ruler of the Papal States from 15 February 1775 until his death in 1799. He condemned the French Revolution and the resulting suppression of the Catholic Church in France. In 1796, French troops commanded by Napoleon Bonaparte defeated the papal troops and occupied the Papal States. Refusing to renounce his temporal power, Pius was taken prisoner and transported to France. He died in exile six weeks later in Valence, having reigned for longer than any previous pope. This 1775 oil-on-panel portrait of Pius VI by the Italian painter Pompeo Batoni is in the collection of the National Gallery of Ireland.

Wikipedia Picture of the Day - February 21st, 2020 - Pullman porter (Narrated by Brian)
This picture is a color lithograph advertisement from 1894, showing the interior of a Pullman dining car belonging to the Cincinnati, Hamilton and Dayton Railway. It depicts two men seated at a table being served by an African-American Pullman porter. Through the window, the Mosler Safe Works in Hamilton, Ohio can be seen, with newly manufactured goods being loaded onto barges on the Great Miami River.
Starting soon after the American Civil War, George Pullman sought out former slaves to work on his sleeping cars. Until the 1960s, Pullman porters were exclusively black and, in 1925, under the leadership of A. Philip Randolph, they formed the first all-black union, the Brotherhood of Sleeping Car Porters. They were supervised by a Pullman conductor, who was then invariably white. In 1926, Pullman employed more than 10,000 porters, a term that has been superseded by "sleeping car attendant".

Wikipedia Picture of the Day - March 6th, 2021 - Palais Galliera (Narrated by Amy)
The Palais Galliera, formally known as the Musée de la Mode de la Ville de Paris, is a museum of fashion and fashion history located in the 16th arrondissement of Paris, France. Following the death of her husband in 1876, the Duchess of Galliera gave land and funds for the erection of a museum to house his collection of paintings and fine art that she proposed to give to the state. The building was completed in 1894, but the collections were in fact donated to Genoa, Italy, where they are now displayed at the Palazzo Rosso and the Palazzo Bianco.

Astronomy Picture of the Day - June 2nd, 2023 - Messier 101 (Narrated by Brian)
Big, beautiful spiral galaxy M101 is one of the last entries in Charles Messier's famous catalog, but definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way. M101 was also one of the original spiral nebulae observed by Lord Rosse's large 19th century telescope, the Leviathan of Parsontown. Assembled from 51 exposures recorded by the Hubble Space Telescope in the 20th and 21st centuries, with additional data from ground based telescopes, this mosaic spans about 40,000 light-years across the central region of M101 in one of the highest definition spiral galaxy portraits ever released from Hubble. The sharp image shows stunning features of the galaxy's face-on disk of stars and dust along with background galaxies, some visible right through M101 itself. Also known as the Pinwheel Galaxy, M101 lies within the boundaries of the northern constellation Ursa Major, about 25 million light-years away.

Astronomy Picture of the Day - March 14th, 2020 - Moonrise and Mountain Shadow (Narrated by Emma)
What phase of the Moon is 3.14 radians from the Sun? The Full Moon, of course. Even though the Moon might look full for several days, the Moon is truly at its full phase when it is 3.14 radians (aka 180 degrees) from the Sun in ecliptic longitude. That's opposite the Sun in planet Earth's sky. Rising as the Sun set on March 9, only an hour or so after the moment of its full phase, this orange tinted and slightly flattened Moon still looked full. It was photographed opposite the setting Sun from Teide National Park on the Canary Island of Tenerife. Also opposite the setting Sun, seen from near the Teide volcano peak about 3,500 meters above sea level, is the mountain's rising triangular shadow extending into Earth's dense atmosphere. Below the distant ridge line on the left are the white telescope domes of Teide Observatory

Wikipedia Picture of the Day - January 27th, 2021 - Yellow badge (Narrated by Matthew)
Yellow badges are badges that Jews were ordered to wear in public during periods of the Middle Ages by the ruling Christians and Muslims, and in Nazi Germany in the 1940s. The badges served to mark the wearer as a religious or ethnic outsider, and often served as a badge of shame. This is a Belgian version of the yellow badge, with a black "J" on a yellow Star of David; from 1942, the wearing of such badges was compulsory for Jews in German-occupied Belgium. The badge pictured is in the collection of the Kazerne Dossin Memorial, Museum and Documentation Centre in Mechelen, Belgium.

Wikipedia Picture of the Day - December 27th, 2019 - Chinstrap penguin (Narrated by Brian)
The chinstrap penguin (Pygoscelis antarcticus) is a species of penguin that inhabits land masses in the Southern Pacific and Antarctic Oceans. The bird's black back and white underparts provide camouflage in the form of countershading when viewed from above or below, helping it to avoid detection by its predators, which include the leopard seal, the southern giant petrel, the brown skua and the south polar skua. The chinstrap penguin grows to a length of 68–76 cm (27–30 in) and a weight of 3.2–5.3 kg (7.1–11.7 lb), with the weight varying with the time of year. Males are greater in weight and height than females.
This picture shows a chinstrap penguin photographed on Deception Island, in the Antarctic archipelago of the South Shetland Islands.
