APOD: 2021-08-19 - Bright Meteor, Starry Sky (Narrated by Joanna)
Astronomy Picture of the Day - August 19th, 2021 - Bright Meteor, Starry Sky (Narrated by Joanna)
Plowing through Earth's atmosphere at 60 kilometers per second, this bright perseid meteor streaks along a starry Milky Way. Captured in dark Portugal skies on August 12, it moves right to left through the frame. Its colorful trail starts near Deneb (alpha Cygni) and ends near Altair (alpha Aquilae), stars of the northern summer triangle. In fact this perseid meteor very briefly outshines both, two of the brightest stars in planet Earth's night. The trail's initial greenish glow is typical of the bright perseid shower meteors. The grains of cosmic sand, swept up dust from periodic comet Swift-Tuttle, are moving fast enough to excite the characteristic green emission of atomic oxygen at altitudes of 100 kilometers or so before vaporizing in an incandescent flash.

Astronomy Picture of the Day - January 11th, 2024 - Quadrantids of the North (Narrated by Joanna)
Named for a forgotten constellation, the Quadrantid Meteor Shower puts on an annual show for planet Earth's northern hemisphere skygazers. The shower's radiant on the sky lies within the old, astronomically obsolete constellation Quadrans Muralis. That location is not far from the Big Dipper asterism, known to some as the Plough, at the boundaries of the modern constellations Bootes and Draco. In fact the Big Dipper "handle" stars are near the upper right corner in this frame, with the meteor shower radiant just below. North star Polaris is toward the top left. Pointing back toward the radiant, Quadrantid meteors streak through the night in this skyscape from Jangsu, South Korea. The composite image was recorded in the hours around the shower's peak on January 4, 2024. A likely source of the dust stream that produces Quadrantid meteors was identified in 2003 as an asteroid.

Astronomy Picture of the Day - May 4th, 2024 - 3 ATs (Narrated by Emma)
Despite their resemblance to R2D2, these three are not the droids you're looking for. Instead, the enclosures house 1.8 meter Auxiliary Telescopes (ATs) at Paranal Observatory in the Atacama Desert region of Chile. The ATs are designed to be used for interferometry, a technique for achieving extremely high resolution observations, in concert with the observatory's 8 meter Very Large Telescope units. A total of four ATs are operational, each fitted with a transporter that moves the telescope along a track allowing different arrays with the large unit telescopes. To work as an interferometer, the light from each telescope is brought to a common focal point by a system of mirrors in underground tunnels. Above these three ATs, the Large and Small Magellanic Clouds are the far, far away satellite galaxies of our own Milky Way. In the clear and otherwise dark southern skies, planet Earth's greenish atmospheric airglow stretches faintly along the horizon.

Wikipedia Picture of the Day - May 6th, 2020 - Silver certificate (Narrated by Matthew)
Silver certificates were issued by the Republic of Cuba between 1934 and 1949. Prior and subsequent issues of Cuban banknotes were engraved and printed by non-governmental private banknote companies in the United States, but the series from 1934 to 1949 was designed, engraved, and printed by the Bureau of Engraving and Printing of the U.S. government.
This is a certified proof of a five-peso silver certificate, prepared in 1936. The obverse depicts Dominican military officer Máximo Gómez, with the engraved signatures of Ricardo Ponce (Secretary of the Treasury) and José Agripino Barnet (President of the Republic). The reverse, printed in orange, bears the Cuban coat of arms. This proof is part of the National Numismatic Collection at the Smithsonian Institution's National Museum of American History.

Wikipedia Picture of the Day - March 4th, 2021 - Coat of arms of Vermont (Narrated by Joanna)
This historical depiction of the coat of arms of Vermont was illustrated by American engraver Henry Mitchell in State Arms of the Union, published in 1876 by Louis Prang. The escutcheon depicts a green landscape, beyond which are high mountains and a yellowish sky; in the center grows a pine tree, between three erect yellow sheaves and a red cow. The state's official motto, "Freedom and Unity", appears below the shield.

Wikipedia Picture of the Day - March 4th, 2020 - Argiope pulchella (Narrated by Matthew)
Argiope pulchella is a species of orb-weaving spider belonging to the family Araneidae, native to India and south-eastern Asia. This picture, taken in the Indian state of Kerala, shows a female A. pulchella spider in the middle of its web, with a male visible above it on the right. The male is "shuddering", vibrating the web as part of a courtship ritual, with males that shudder at high rates for long periods being preferred by the female to those with lesser skills; such activity may also reduce the likelihood that the male will be cannibalised by the female after mating. A zig-zag stabilimentum, a form of web decoration whose function is not precisely known, can be seen at the bottom right of the photograph.

Wikipedia Picture of the Day - March 26th, 2021 - Dvenadsat Apostolov (Narrated by Brian)
Dvenadsat Apostolov was a pre-dreadnought battleship built for the Imperial Russian Navy, the sole ship of her class. Launched in 1890, she entered service with the Black Sea Fleet in 1893, taking part in the failed attempt to recapture the mutinous battleship Potemkin in 1905. Decommissioned and disarmed in 1911, she was used as a stand-in for the title ship during the 1925 filming of the Battleship Potemkin before finally being scrapped in 1931.

Wikipedia Picture of the Day - February 28th, 2024 - Scarlet-chested sunbird (Narrated by Matthew)
The scarlet-chested sunbird (Chalcomitra senegalensis) is a species of bird in the sunbird family, Nectariniidae. It is found in many areas of sub-Saharan Africa, and from South Sudan to South Africa. Adult males of this species have a characteristic red–scarlet coloured breast and an iridescent green patch on top of their heads, while the female is dark brown with no supercilium. It inhabits woodland and gardens, at elevations of up to 2,400 metres (7,900 ft). The bird is around 13 to 15 centimetres (5.1 to 5.9 in) in length, with males having a weight of 7.5 to 17.2 grams (0.26 to 0.61 oz) and females weighing 6.8 to 15.3 grams (0.24 to 0.54 oz). This female scarlet-chested sunbird of the subspecies C. s. lamperti was photographed feeding on an Aloe zebrina flower in the Soysambu Conservancy, Kenya.
