- A globular cluster is a spheroidal conglomeration of stars that is bound together by gravity, with a higher concentration of stars towards their centers. They can contain anywhere from tens of thousands to many millions of member stars, all orbiting in a stable, compact formation. Globular clusters are similar in form to dwarf spheroidal galaxies, and the distinction between the two is not always clear. Their name is derived from Latin globulus (small sphere). Globular clusters are occasionally known simply as “globulars”.
- Janusz Korczak (Wikipedia)
Janusz Korczak, the pen name of Henryk Goldszmit (22 July 1878 or 1879 – 7 August 1942), was a Polish Jewish pediatrician, educator, children’s author and pedagogue known as Pan Doktor (“Mr. Doctor”) or Stary Doktor (“Old Doctor”). He was an early children’s rights advocate, in 1919 drafting a children’s constitution. ¶ After spending many years working as a principal of an orphanage in Warsaw, he refused sanctuary repeatedly and stayed with his orphans when the entire population of the institution was sent from the ghetto to the Treblinka extermination camp during the Grossaktion Warschau of 1942.
