Wikipedia Picture of the Day - August 13th, 2020 - German Papiermark (Narrated by Joanna)
The Papiermark is the name given to the German currency from 4 August 1914, when the link between the Goldmark and gold was abandoned. In particular, the name is used for the banknotes issued during the period of hyperinflation in Germany in 1922 and especially 1923. During this period, the Papiermark was also issued by the Free City of Danzig. The last of five series of the Danzig mark was the 1923 inflation issue, which consisted of denominations of 1 million to 10 billion issued from August to October 1923. The Danzig mark was replaced on 22 October 1923 by the Danzig gulden. This five-billion-mark banknote, issued on 11 October 1923, is in the National Numismatic Collection of the Smithsonian Institution's National Museum of American History.
Other denominations: 1 million 10 million 100 million 500 million 10 billion

Beautiful News Daily - September 17th, 2020 - California initiative breeds infertility into mosquitoes, cutting their numbers (Narrated by Joanna)
Malaria kills hundreds of thousands of people every year. One of Google’s sister companies is now attempting to wipe it off the map, along with other mosquito-borne diseases such as dengue fever. The strategy – to make them infertile – could help to eradicate malaria forever.

Wikipedia Picture of the Day - July 8th, 2021 - William Windom (Narrated by Joanna)
William Windom (1827–1891) was an American politician from Minnesota. He served as a Republican in the United States House of Representatives from 1859 to 1869, and in the United States Senate for three periods between 1870 and 1883. He also served twice as Secretary of the Treasury under three presidents. This line engraving of Windom was produced around 1902 by the Department of the Treasury's Bureau of Engraving and Printing (BEP) as part of a BEP presentation album of the first 42 secretaries of the treasury.

Wikipedia Picture of the Day - January 20th, 2020 - Bracket (Narrated by Brian)
In architecture, a bracket is a structural or decorative member that attaches a smaller object to a larger one. It projects from a wall, usually to carry weight and sometimes to strengthen an angle. Corbels and consoles are types of brackets. This picture shows a classical decorative bracket, attaching the base of a balcony to the walls of the chapel at Greenwich Hospital, London. The plasterwork was created by hand in situ by the eminent stuccoist John Papworth.
Greenwich Hospital (originally the Royal Hospital for Seamen) was founded in 1694 to provide a home for retired seamen of the Royal Navy, support for their widows and education for their children. Designed by Sir Christopher Wren, the chapel was not completed until 1742. The present chapel dates from 1779 to 1789, having been rebuilt to a design by James Stuart following a devastating fire that gutted the previous structure. The buildings of the hospital were later used by the Royal Naval College and the University of Greenwich, and are now known as the Old Royal Naval College, a World Heritage Site.

Astronomy Picture of the Day - March 3rd, 2021 - Stars over an Erupting Volcano (Narrated by Salli)
Mt. Etna has been erupting for hundreds of thousands of years. Located in Sicily, Italy, the volcano produces lava fountains over one kilometer high. Mt. Etna is not only one of the most active volcanoes on Earth, it is one of the largest, measuring over 50 kilometers at its base and rising nearly 3 kilometers high. Pictured erupting last month, a lava plume shoots upwards, while hot lava flows down the volcano's exterior. Likely satellite trails appear above, while ancient stars dot the sky far in the distance. This volcanic eruption was so strong that nearby airports were closed to keep planes from flying through the dangerous plume. The image foreground and background were captured consecutively by the same camera and from the same location. Please take a short survey in aesthetics & astronomy: Sonification

Beautiful News Daily - July 17th, 2020 - Supercapacitor Buses Are A Thing Now (Narrated by Brian)
Supercapacitors don’t hold as much energy as batteries. But they last for years, and charge really quickly. That makes them perfect for use in mass transit systems.
In China, supercapacitor buses run all day, fully loaded and with air conditioning on. Some models can charge in just 10 seconds. Better still: they consume 30-50% less energy than other electric vehicles. Beautiful!

Wikipedia Picture of the Day - April 25th, 2021 - Mangrove pitta (Narrated by Emma)
The mangrove pitta (Pitta megarhyncha) is a species of passerine bird in the family Pittidae native to the eastern Indian subcontinent and the westernmost parts of Southeast Asia. In general, pittas are reclusive birds and difficult to observe, but this species is easier than most, calling from high in mangrove trees, and responding readily to recordings of its voice. This mangrove pitta was photographed at Pulau Ubin in Singapore.

Astronomy Picture of the Day - April 8th, 2024 - The Changing Ion Tail of Comet Pons-Brooks (Narrated by Emma)
How does a comet tail change? It depends on the comet. The ion tail of Comet 12P/Pons–Brooks has been changing markedly, as detailed in the featured image sequenced over nine days from March 6 to 14 (top to bottom). On some days, the comet's ion tail was relatively long and complex, but not every day. Reasons for tail changes include the rate of ejection of material from the comet's nucleus, the strength and complexity of the passing solar wind, and the rotation rate of the comet. Over the course of a week, apparent changes even include a change of perspective from the Earth. In general, a comet's ion tail will point away from the Sun, as gas expelled is pushed out by the Sun's wind. Today, Pons-Brooks may become a rare comet suddenly visible in the middle of the day for those able to see the Sun totally eclipsed by the Moon.
