Sirius

Sirius.
Sirius, designated Alpha Canis Majoris, is the brightest star in the night sky with a visual magnitude of −1.46. It is a close binary star system, consisting of Sirius A, a white main-sequence star, and a faint companion white dwarf, Sirius B, which was originally a massive bluish star that became a red giant before shedding its outer layers and collapsing to a white dwarf. It is one of Earth's near neighbors, at 2.6 parsecs (8.6 light-years). Sirius A is about twice as massive as the Sun and has an absolute magnitude of 1.42. It is 25 times more luminous than the Sun but has a lower luminosity than other bright stars. The system is 200 to 300 million years old. Sirius is known as the "Dog Star", due to its prominence in its constellation, Canis Major. The rising of Sirius marked the flooding of the Nile in Ancient Egypt and the "dog days" of summer for the ancient Greeks, while to the Polynesians it was important for Pacific navigation.

Duke and Duchess of Windsor's 1937 tour of Germany

Duke and Duchess of Windsor's 1937 tour of Germany.
The Duke and Duchess of Windsor's 1937 tour of Germany was opposed by the British government, which feared that Nazi Germany would use the visit for propaganda. After Edward had abdicated the British throne in December 1936, his brother George VI became king. Given the title Duke of Windsor, Edward married Wallis Simpson in June 1937. He appeared to have been sympathetic to Germany in this period and announced his intention to travel there privately to tour factories. He promised the British government that he would keep a low profile, and the tour went ahead between 12 and 23 October. The Duke and Duchess visited factories, many of which were producing materiel for the war effort, and the Duke inspected German troops (pictured). The Windsors dined with prominent Nazis including Joseph Goebbels, Hermann Göring, Joachim von Ribbentrop, and Albert Speer; they also had tea with Adolf Hitler at his house at Berchtesgaden.

Wells and Wellington affair

Wells and Wellington affair.
The Wells and Wellington affair was a dispute involving the Australian Journal of Herpetology, a scientific journal on the study of amphibians and reptiles published beginning in 1981 by the Australian Herpetologists' League. Richard Wells, a student, served as the editor-in-chief of the peer-reviewed periodical, with an editorial board of three researchers. Wells stopped communicating with his board for two years before publishing three unreviewed papers in the journal in 1983 and 1985 which he coauthored with teacher C. Ross Wellington. The papers reorganized the taxonomy of Australia's and New Zealand's amphibians and reptiles, and proposed over 700 changes to their scientific names. The herpetological community brought a case to the ICZN to suppress the new names, but the commission eventually opted not to decide, leaving some of Wells and Wellington's names available. As of 2020, 24 of their specific names remained valid senior synonyms (example pictured).
