Wikipedia Picture of the Day - March 25th, 2020 - View from Stalheim (Narrated by Matthew) View from Stalheim is an 1842 oil-on-canvas painting by Norwegian artist Johan Christian Dahl, depicting the view from the village of Stalheim, in the county of Vestland in western Norway. A major work of Romantic nationalism, it is regarded as a national icon and one of Dahl's best works. The scene overlooks the Nærøy Valley, with the sugarloaf-shaped peak of Jordalsnuten in the background, framed by other peaks and a rainbow. A small village in the centre is illuminated by the late afternoon sun. One of Dahl's purposes in the painting was that of realism; the other was to capture the glory and magnificence of the mountains, and his country's culture associated with it. He had trouble with the painting, and avoided similarly large works after its completion. The painting is now in the collection of the National Gallery in Oslo.

Astronomy Picture of the Day - March 28th, 2023 - A Multiple Green Flash Sunset (Narrated by Amy) Yes, but can your green flash do this? A green flash at sunset is a rare event that many Sun watchers pride themselves on having seen.  Once thought to be a myth, a green flash is now understood to occur when the Earth's atmosphere acts like both a prism and a lens. Different atmospheric layers create altitude-variable refraction that takes light from the top of the Sun and disperses its colors, creates two images, and magnifies it in just the right way to make a thin sliver appear green just before it disappears. Pictured, though, is an even more unusual sunset. From the high-altitude Cerro Tololo Inter-American Observatory in Chile one day last April, the Sun was captured setting beyond an atmosphere with multiple distinct thermal layers, creating several  mock images of the Sun.  This time and from this location, many of those layers produced a green flash simultaneously. Just seconds after this multiple-green-flash event was caught by two well-surprised astrophotographers, the Sun set below the clouds. Image Credit & Copyright: T. SlovinskýP.

Wikipedia Picture of the Day - January 12th, 2023 - Rhodochrosite (Narrated by Joanna) Rhodochrosite is a carbonate mineral with the chemical composition MnCO3 (manganese carbonate). In its (rare) pure form, it is typically a rose-red color, but can also be shades of pink to pale brown. It streaks white, and its Mohs hardness varies between 3.5 and 4.5. Its specific gravity is between 3.45 and 3.6. The mineral is formed by oxidation of manganese ore, and is found in South Africa, China and South America. It is Argentina's national gemstone, and was named as the official state gemstone by the U.S. state of Colorado in 2002. This photograph shows a rhodochrosite specimen on a matrix that originated from Peru.
