Wikipedia Picture of the Day - September 19th, 2023 - Mabel Vernon (Narrated by Salli)
Mabel Vernon (September 19, 1883 – September 2, 1975) was an American suffragist, pacifist, and a national leader in the suffrage movement in the United States. A Quaker and a member of the National American Woman Suffrage Association, Vernon was inspired by the methods used by the Women's Social and Political Union in the United Kingdom. She was one of the principal members of the Congressional Union for Woman Suffrage, and helped to organize the Silent Sentinels' protests that involved daily picketing of Woodrow Wilson's White House. This photograph of Vernon was taken around 1917, the year in which she was elected the secretary of the National Woman's Party, and became one of the first six women to be arrested while picketing the White House, under charges of "obstructing the traffic". They were each ordered to pay a $25 fine or spend three days in jail; all of the women insisted they were innocent and refused to pay the fine.

Astronomy Picture of the Day - November 27th, 2022 - Supernumerary Rainbows over New Jersey (Narrated by Brian)
Yes, but can your rainbow do this? After the remnants of Hurricane Florence passed over the Jersey Shore, New Jersey, USA in 2018, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of rainbows. Over the course of a next half hour, to the delight of the photographer and his daughter, vibrant supernumerary rainbows faded in and out, with at least five captured in this featured single shot. Supernumerary rainbows only form when falling water droplets are all nearly the same size and typically less than a millimeter across. Then, sunlight will not only reflect from inside the raindrops, but interfere, a wave phenomenon similar to ripples on a pond when a stone is thrown in. In fact, supernumerary rainbows can only be explained with waves, and their noted existence in the early 1800s was considered early evidence of light's wave nature.

Astronomy Picture of the Day - April 23rd, 2020 - Lyrid Meteor Streak (Narrated by Joanna)
rth's annual Lyrid Meteor Shower peaked before dawn yesterday, as our fair planet plowed through debris from the tail of long-period comet Thatcher. In crisp, clear and moonless predawn skies over Brown County, Indiana this streak of vaporizing comet dust briefly shared a telephoto field of view with stars and nebulae along the Milky Way. Alpha star of the constellation Cygnus, Deneb lies near the bright meteor's path along with the region's dark interstellar clouds of dust and the recognizable glow of the North America nebula (NGC 7000). The meteor's streak points back to the shower's radiant, its apparent point of origin on the sky. That would be in the constellation Lyra, near bright star Vega and off the top edge of the frame.

Astronomy Picture of the Day - September 9th, 2021 - M16 Cose Up (Narrated by Joanna)
A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region adopts the colorful Hubble palette and includes cosmic sculptures made famous in Hubble Space Telescope close-ups of the starforming complex. Described as elephant trunks or Pillars of Creation, dense, dusty columns rising near the center are light-years in length but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. Extending from the ridge of bright emission left of center is another dusty starforming column known as the Fairy of Eagle Nebula. M16 lies about 7,000 light-years away, an easy target for binoculars or small telescopes in a nebula rich part of the sky toward the split constellation Serpens Cauda (the tail of the snake).

Wikipedia Picture of the Day - July 22nd, 2023 - Lake Sherburne (Narrated by Amy)
Lake Sherburne is located in the Many Glacier region of Glacier National Park, in the U.S. state of Montana. The lake is a reservoir, formed by Lake Sherburne Dam, which impounded Swiftcurrent Creek and was constructed in between 1914 and 1921.

Astronomy Picture of the Day - February 6th, 2020 - Southern Moonscape (Narrated by Joanna)
The Moon's south pole is near the top of this detailed telescopic view. Looking across the rugged southern lunar highlands it was captured from southern California, planet Earth. At the Moon's third quarter phase the lunar terminator, the sunset shadow line, is approaching from the left. The scene's foreshortened perspective heightens the impression of a dense field of craters and makes the craters themselves appear more oval shaped close to the lunar limb. Below and left of center is sharp-walled crater Tycho, 85 kilometers in diameter. Young Tycho's central peak is still in sunlight, but casts a long shadow across the crater floor. The large prominent crater to the south (above) Tycho is Clavius. Nearly 231 kilometers in diameter its walls and floor are pocked with smaller, more recent, overlaying impact craters. Mountains visible along the lunar limb at the top can rise about 6 kilometers or so above the surrounding terrain.

Astronomy Picture of the Day - December 9th, 2020 - Arecibo Telescope Collapse (Narrated by Salli)
This was one great scientific instrument. Starting in 1963, the 305-meters across Arecibo Telescope in Puerto Rico USA reigned as the largest single-dish radio telescope in the world for over 50 years. Among numerous firsts and milestones, data from Arecibo has been used to measure the spin of Mercury, map the surface of Venus, discover the first planets outside of our Solar System, verify the existence of gravitational radiation, search for extraterrestrial intelligence, and, reportedly, locate hidden military radar by tracking their reflections from the Moon. Past its prime and in the process of being decommissioned, the Arecibo Telescope suffered a catastrophic structural collapse early this month, as seen in the featured composite video.

Wikipedia Picture of the Day - February 13th, 2024 - Dale Creek Crossing (Narrated by Salli)
The Dale Creek Crossing was a 650-foot (200 m) bridge in the southeastern Wyoming Territory, United States, completed in 1868. It was constructed by the Union Pacific Railroad as part of the first transcontinental railroad. With a maximum height of 150 feet (46 m) and with a necessity of cutting through solid rock on both sides, it was one of the most difficult parts of the line to build. The original bridge was built of wood, and its trestles began swaying in the wind from the opening day. The original bridge was replaced on the 1868 piers in 1876 by an iron bridge, manufactured by the American Bridge Company, and this was dismantled entirely in 1901 when the Union Pacific completed construction of a new alignment over Sherman Hill as part of a reconstruction project which shortened the Overland Route. This photograph of the Dale Creek Crossing was taken during construction in 1868 by the project's official photographer, Andrew J. Russell.

Wikipedia Picture of the Day - October 13th, 2023 - Sea Girt Light (Narrated by Brian)
The Sea Girt Light is a lighthouse marking the inlet leading to the Wreck Pond in Sea Girt, New Jersey, United States. It is located on a stretch of the New Jersey shore between the Barnegat and Navesink lighthouses. Its site was chosen after a previous proposal for a lighthouse at Manasquan Inlet was found infeasible, and it was first lit in December 1896. Protections against sand erosion were added in 1900 and the 1920s, and in 1921, Sea Girt Light was equipped with a radio beacon for use in fog, the first such installation on a shore-based light in the US. At the outset of World War II, the light was deactivated and the lens removed; the house was remodeled to serve as a dormitory for a Coast Guard observation post. At the end of the war, an aerobeacon was mounted atop the tower, with the original lighthouse being decommissioned. In 1955, a new beacon was erected away from the building on a steel tower on the lawn. The building was sold to the borough of Sea Girt shortly after. It was used for the town library and for meeting space for many years, while the beacon itself remained operational until 1977. The building was taken over by the Sea Girt Lighthouse Citizens Committee in 1980 and was subsequently restored. It now serves as a museum, offering tours.

Astronomy Picture of the Day - September 18th, 2024 - The Mermaid Nebula Supernova Remnant (Narrated by Salli)
New stars are born from the remnants of dead stars. The gaseous remnant of the gravitational collapse and subsequent death of a very massive star in our Milky Way created the G296.5+10.0 supernova remnant, of which the featured Mermaid Nebula is part. Also known as the Betta Fish Nebula, the Mermaid Nebula makes up part of an unusual subclass of supernova remnants that are two-sided and nearly circular. Originally discovered in X-rays, the filamentary nebula is a frequently studied source also in radio and gamma-ray light. The blue color visible here originates from doubly ionized oxygen (OIII), while the deep red is emitted by hydrogen gas. The nebula's mermaid-like shape has proven to be useful for measurements of the interstellar magnetic field.
