Mimas, a small, heavily cratered icy moon, appears near the bottom of the frame against the blue northern latitudes of Saturn. Dark curved lines of the planet’s ring shadows stretch across Saturn’s atmosphere. The image is a true-color view taken by Cassini’s narrow-angle camera on 18 January 2005.

During #WW1, Marie Curie created a vehicle that contained a hospital bed, generator, X-ray machine & photographic darkroom equipment. These “petite Curies" (below) could be driven right up to the Front. Curie trained 150 women as radiology technicians. #histmed #skystorians #histsci

A VICTORIAN MERMAN Objects like this were often made from the torsos of monkeys and the tails of fish. They were displayed by showmen like P. T Barnum to audiences who believed they were real. This particular one is on display at the Horniman Museum, London. #skystorians #histmed #histsci

A strange looking creature with a fish tail and animal-like arms with claws. The head looks a bit human, with no hair and sharp teeth.

Marie Curie's notebooks are still radioactive & must be kept in a lead-lined box. If you visit the Pierre & Marie Curie Collection at the Bibliotheque Nationale in France, many of her personal items—from her furniture to cookbooks—require protective clothing to be safely handled. #histsci

Einstein's blackboard, which was preserved after his 2nd lecture at Oxford University on May 16, 1931. Its equations connect the age, density and size of the universe. After the lecture, the blackboard was taken directly to the History of Science Museum, where it is on display today. #histsci

🧵 This image provides an overview of the 25 brightest stars in the night sky (as seen by humans). It shows them in true color, highlighting their beauty and diversity. ➡️ apod.nasa.gov/apod/ap25061... For more, read the thread. 🔭 🧪 #stellarastro #science #Universe #Astronomy #HistSci

The image presents a visual representation of the 25 brightest stars in the night sky, shown in true color against a black background that simulates the starry sky. The stars are arranged in a grid, each accompanied by its name standardized by the International Astronomical Union (IAU). Each star is depicted as a bright point of light with spikes, showing varying sizes and colors that reflect their apparent magnitude and surface temperature: some appear white, others yellow-orange or reddish. There are no lines or constellations depicted, just isolated stars with their names written in white lettering. The overall effect is that of a stylized night sky, with a clear, scientific aesthetic designed to highlight the brightness and color of each star.
The stars are: Sirius, Canopus, Rigil Kentaurus, Arcturus, Vega, Capella, Rigel, Procyon, Achernar, Betelgeuse, Hadar, Altair, Acrux, Aldebaran, Antares, Spica, Pollux, Fomalhaut, Deneb, Mimosa, Regulus, Adhara, Shaula, Castor, Gacrux.
