- Raoul Gustaf Wallenberg (4 August 1912 – disappeared 17 January 1945) was a Swedish architect, businessman, diplomat, and humanitarian. He saved thousands of Jews in German-occupied Hungary during the Holocaust from German Nazis and Hungarian fascists during the later stages of World War II. While serving as Sweden’s special envoy in Budapest between July and December 1944, Wallenberg issued protective passports and sheltered Jews in buildings he declared as Swedish territory.
- Red dwarf (Wikipedia)
A red dwarf is the smallest kind of star on the main sequence. Red dwarfs are by far the most common type of fusing star in the Milky Way, at least in the neighborhood of the Sun. However, due to their low luminosity, individual red dwarfs cannot be easily observed. From Earth, not one star that fits the stricter definitions of a red dwarf is visible to the naked eye. Proxima Centauri, the star nearest to the Sun, is a red dwarf, as are fifty of the sixty nearest stars. According to some estimates, red dwarfs make up three-quarters of the fusing stars in the Milky Way.
