APOD: 2020-09-16 - Gravel Ejected from Asteroid Bennu (Narrated by Salli)
Astronomy Picture of the Day - September 16th, 2020 - Gravel Ejected from Asteroid Bennu (Narrated by Salli)
Why does asteroid Bennu eject gravel into space? No one is sure. The discovery, occurring during several episodes by NASA's visiting ORISIS-REx spacecraft, was unexpected. Leading ejection hypotheses include impacts by Sun-orbiting meteoroids, sudden thermal fractures of internal structures, and the sudden release of a water vapor jet. The featured two-image composite shows an ejection event that occurred in early 2019, with sun-reflecting ejecta seen on the right. Data and simulations show that large gravel typically falls right back to the rotating 500-meter asteroid, while smaller rocks skip around the surface, and the smallest rocks completely escape the low gravity of the Earth approaching, diamond-shaped asteroid. Jets and surface ejection events were thought to be predominantly the domain of comets, responsible for their tails, comas, and later meteor showers on Earth. Robotic OSIRIS-REx arrived at 101955 Bennu in late 2018, and is planned to touchdown to collect a surface sample in October 2020. If all goes well, this sample will then be returned to Earth for a detailed analysis during 2023. Bennu was chosen as the destination for OSIRIS-REx in part because its surface shows potential to reveal organic compounds from the early days of our Solar System, compounds that could have been the building blocks for life on Earth. Experts Debate: How will humanity first discover extraterrestrial life?

Astronomy Picture of the Day - February 16th, 2023 - The Hydra Cluster of Galaxies (Narrated by Joanna)
Once upon a midnight dreary, while I pondered weak and weary, O'er volumes of astronomy and forgotten lore, I stumbled upon this snapshot, cosmic and eerie, A sight that filled my heart with awe and more. Two stars, like sentinels, anchored the foreground, Of our Milky Way galaxy, a sight to behold, Beyond them, a cluster of Hydra, galaxies abound, 100 million light-years away, a story to be told. Three large galaxies, ellipticals and a spiral blue, Dominant and grand, each 150,000 light-years wide, But it was the overlapping pair that caught my view, Cataloged as NGC 3314, a sight I cannot hide. Abell 1060, the Hydra galaxy cluster's name, One of three large galaxy clusters close to our Milky Way, A universe bound by gravity, a celestial game, Where clusters align over larger scales, I cannot sway. At a distance of 100 million light-years, this snapshot's size, 1.3 million light-years across, a cosmic delight, A momentary glimpse into the universe's guise, But even this shall fade, and be nevermore in sight.

Astronomy Picture of the Day - August 15th, 2021 - Perseid Rain (Narrated by Brian)
Comet dust rained down on planet Earth last week, streaking through dark skies in the annual Perseid meteor shower. The featured picture is a composite of many images taken from the same location over the peak night of the Perseids. The umbrella was not needed as a shield from meteors, since they almost entirely evaporate high in the Earth's atmosphere. Many of the component images featured individual Perseids, while one image featured the foreground near Jiuquan City, Gansu Province, China. The stellar background includes the central band of our Milky Way Galaxy, appearing nearly vertical, as well as the planets Jupiter and Saturn on the left. Although the comet dust particles are traveling parallel to each other, the resulting shower meteors clearly seem to radiate from a single point on the sky -- the radiant in the eponymous constellation Perseus. The image captured so long an angular field that the curvature of the sky is visible in the trajectory of the Perseids. Notable APOD Image Submissions: Perseid Meteor Shower 2021

Wikipedia Picture of the Day - January 24th, 2022 - Winter Palace (Narrated by Brian)
The Winter Palace is a palace in Saint Petersburg that served as the official residence of the Russian emperors from 1732 to 1917. The palace and its precincts now house the Hermitage Museum. The green-and-white palace has the overall shape of an elongated rectangle, with a 215-metre-long (705 ft) and 30-metre-high (98 ft) principal facade. The Winter Palace has been calculated to contain 1,886 doors, 1,945 windows, 1,500 rooms and 117 staircases. This aerial view of the palace was taken in 2016.

apod-2024-03-12-a-galaxy-shaped-rocket
Astronomy Picture of the Day - March 12th, 2024 - A Galaxy-Shaped Rocket Exhaust Spiral (Narrated by Amy)
What's that over the horizon? What may look like a strangely nearby galaxy is actually a normal rocket's exhaust plume -- but unusually backlit. Although the SpaceX Falcon 9 rocket was launched from Cape Canaveral in Florida, USA, its burned propellant was visible over a much wider area, with the featured photograph being taken from Akureyri, Iceland. The huge spaceship was lifted off a week ago, and the resulting spectacle was captured soon afterward with a single 10-second smartphone exposure, before it quickly dissipated. Like noctilucent clouds, the plume's brightness is caused by the Twilight Effect, where an object is high enough to be illuminated by the twilight Sun, even when the observer on the ground experiences the darkness of night. The spiral shape is likely caused by high winds pushing the expelled gas into the shape of a corkscrew, which, when seen along the trajectory, looks like a spiral. Stars and faint green and red aurora appear in the background of this extraordinary image.

Astronomy Picture of the Day - February 25th, 2023 - Crescent Moon Occultation (Narrated by Emma)
On February 22, a young Moon shared the western sky at sunset with bright planets Venus and Jupiter along the ecliptic plane. The beautiful celestial conjunction was visible around planet Earth. But from some locations Jupiter hid for a while, occulted by the crescent lunar disk. The Solar System's ruling gas giant was captured here just before it disappeared behind the the Moon's dark edge, seen over the Río de la Plata at Colonia del Sacramento, Uruguay. In the serene river and skyscape Venus is not so shy, shining brightly closer to the horizon through the fading twilight. Next week Venus and Jupiter will appear even closer in your evening sky.

Wikipedia Picture of the Day - March 8th, 2021 - Henry Mayer (Narrated by Brian)
This is a cartoon by the German-American cartoonist and animator Henry Mayer (1868–1954), entitled The Awakening, which first appeared in the magazine Puck in February 1915. Published in support of women's suffrage in the United States, the cartoon depicts Lady Liberty wearing a cape labeled "Votes for Women" and standing astride the states (colored white) that had granted women the right to vote. A poem by Alice Duer Miller is printed beneath.

Beautiful News Daily - September 21st, 2020 - Blood donors In Sweden, Canada & the UK receive a text when their blood is used (Narrated by Salli)
Donated blood saves lives. Services always need new donors to come forward, but also previous ones to return. Sweden was the first to let them know when their blood had been used, followed by Canada and the UK. It means more transparency, more trust. A reminder of the good that’s being done.

Astronomy Picture of the Day - September 1st, 2020 - Salt Water Remnants on Ceres (Narrated by Amy)
Does Ceres have underground pockets of water? Ceres, the largest asteroid in the asteroid belt, was thought to be composed of rock and ice. At the same time, Ceres was known to have unusual bright spots on its surface. These bright spots were clearly imaged during Dawn's exciting approach in 2015. Analyses of Dawn images and spectra indicated that the bright spots arise from the residue of highly-reflective salt water that used to exist on Ceres' surface but evaporated. Recent analysis indicates that some of this water may have originated from deep inside Ceres, indicating Ceres to be a kindred spirit with several Solar System moons, also thought to harbor deep water pockets. The featured video shows in false-color pink the bright evaporated brine named Cerealia Facula in Occator Crater. In 2018, the mission-successful but fuel-depleted Dawn spacecraft was placed in a distant parking orbit, keeping it away from the Ceres' surface for at least 20 years to avoid interfering with any life that might there exist. Experts Debate: How will humanity first discover extraterrestrial life?

Wikipedia Picture of the Day - February 27th, 2021 - A Negress (Narrated by Amy)
A Negress is an 1884 oil-on-canvas painting by the Polish artist Anna Bilińska-Bohdanowicz, depicting an unknown model. The subject is portrayed from the waist up and dressed in a white robe, but is part naked, with one breast exposed. The Japanese hand fan and the source of light that illuminates the figure and is reflected by highlights in the gold bijoux, create a warm and chamber-like atmosphere. Painted in Paris, the painting was looted during World War II. It was returned to the collection of the National Museum in Warsaw in 2012.
