APOD: 2022-02-02 - The Galactic Center in Radio from MeerKAT (Narrated by Salli)
Astronomy Picture of the Day - February 2nd, 2022 - The Galactic Center in Radio from MeerKAT (Narrated by Salli)
What's happening at the center of our galaxy? It's hard to tell with optical telescopes since visible light is blocked by intervening interstellar dust. In other bands of light, though, such as radio, the galactic center can be imaged and shows itself to be quite an interesting and active place. The featured picture shows the latest image of our Milky Way's center by the MeerKAT array of 64 radio dishes in South Africa. Spanning four times the angular size of the Moon (2 degrees), the image is impressively vast, deep, and detailed. Many known sources are shown in clear detail, including many with a prefix of Sgr, since the galactic center is in the direction of the constellation Sagittarius. In our Galaxy's Center lies Sgr A, found here in the image center, which houses the Milky Way's central supermassive black hole. Other sources in the image are not as well understood, including the Arc, just to the left of Sgr A, and numerous filamentary threads. Goals for MeerKAT include searching for radio emission from neutral hydrogen emitted in a much younger universe and brief but distant radio flashes.

Beautiful News Daily - September 12th, 2020 - More Countries Are Protecting Animals (Narrated by Amy)
By protecting animals, we protect ourselves. Billions of us depend on them for food, jobs and income. Caring for them properly is the right thing to do. It also means fewer infectious diseases and improved biodiversity, benefiting the environment and the economy. More countries are now coming to realise this and enshrine protection in law.

Astronomy Picture of the Day - March 11th, 2020 - An Extreme Black Hole Outburst (Narrated by Salli)
Astronomers believe they have now found the most powerful example of a black hole outburst yet seen in our Universe. The composite, false-color featured image is of a cluster of galaxies in the constellation of Ophiuchus, the serpent-bearer. The composite includes X-ray images (from the Chandra X-ray Observatory and XMM-Newton) in purple, and a radio image (from India's Giant Metrewave Radio Telescope) in blue (along with an infrared image of the galaxies and stars in the field in white for good measure). The dashed line marks the border of a cavity blown out by the supermassive black hole which lurks at the center of the galaxy marked by the cross. Radio emission fills this cavity. This big blowout is believed to be due to the black hole eating too much and experiencing a transient bout of "black hole nausea", which resulted in the ejection of a powerful radio jet blasting into intergalactic space. The amount of energy needed to blow this cavity is equivalent to about 10 billion supernova explosions.

Wikipedia Picture of the Day - April 10th, 2020 - Christ Crucified (Narrated by Brian)
Christ Crucified is a 1780 oil-on-canvas painting of the crucifixion of Jesus by Spanish Romantic artist Francisco Goya. He presented it to the Real Academia de Bellas Artes de San Fernando as his reception piece to meet the requirements for admission. The painting is neoclassical in style and is similar to the treatment of the same topic by Velázquez and Anton Raphael Mengs. Goya conforms to the Spanish Baroque iconographic rules for portraying the Crucifixion as laid down by Francisco Pacheco – a black background, four rather than three nails, supported feet, and a trilingual inscription in Hebrew, Greek and Latin affixed to the top of the cross reading 'King of the Jews'. The work now forms part of the permanent collection of the Museo del Prado in Madrid.

Wikipedia Picture of the Day - November 22nd, 2022 - Saint Anne (Narrated by Salli)
Saint Anne is a Makurian wall painting estimated to have been painted between the 8th and 9th centuries, painted a secco with tempera on plaster. The anonymous work, depicting Saint Anne, the mother of Mary, was found at Faras Cathedral in Lower Nubia, located in the north of present-day Sudan. The painting was discovered by a Polish archaeological team during a campaign undertaken in the 1960s under the patronage of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Faras, before the site was flooded by the creation of Lake Nasser. Since 1964, the painting has been in the Faras Gallery at the National Museum in Warsaw.

Wikipedia Picture of the Day - December 30th, 2021 - Grass snake (Narrated by Joanna)
The grass snake (Natrix natrix) is a Eurasian non-venomous colubrid snake that grows to around a metre (3 ft) in length. It is often found near water and feeds almost exclusively on amphibians. Its prey, often common frogs or toads, is caught and swallowed whole. While digesting a large meal, the snake does not travel far, preferring to bask in the sun. Two or three significant food items may supply an individual's needs for the whole season, with the snake finding an underground refuge, not subject to freezing, in which to overwinter. This grass snake was photographed near Storkow in Brandenburg, Germany.

Wikipedia Picture of the Day - October 27th, 2023 - Charon (Narrated by Brian)
Charon is the largest of the five known natural satellites of the dwarf planet Pluto. It has a mean radius of 606 kilometres (377 mi), making it the sixth-largest known trans-Neptunian object after Pluto, Eris, Haumea, Makemake, and Gonggong. With half the radius and one-eighth the mass of Pluto, Charon is a very large moon in comparison to its parent body. Its gravitational influence is such that the barycenter of the Plutonian system lies outside Pluto, and the two bodies are tidally locked to each other. Charon was discovered in 1978 by James W. Christy at the United States Naval Observatory (USNO), using photographic plates taken at USNO Flagstaff Station in Arizona. This photograph of Charon in true color was taken by the NASA spacecraft New Horizons, which flew by the Plutonian system in 2015.

SUPER
supercapacitor-buses-are-a-thing-now
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!

Astronomy Picture of the Day - March 5th, 2020 - The Light, the Dark, and the Dusty (Narrated by Joanna)
This colorful skyscape spans about four full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region's massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 is left of center, also known as the Cave Nebula. About 10 light-years across the cosmic cave's bright walls of gas are ionized by ultraviolet light from the hot young stars around it. Dusty blue reflection nebulae, like vdB 155 at lower right, and dense obscuring clouds of dust also abound on the interstellar canvas. Astronomical explorations have revealed other dramatic signs of star formation, including the bright red fleck of Herbig-Haro (HH) 168. Below center in the frame, the Herbig-Haro object emission is generated by energetic jets from a newborn star.
