- After declaring independence from the Ottoman Empire in 1912, Albania experienced a period of political upheaval that led to a short-lived monarchy, which ended in 1939 when Italy conquered the country. Germany then occupied Albania in 1943, and communist partisans took over the country in 1944. Albania allied itself first with the USSR (until 1960) and then with China (until 1978). In the early 1990s, Albania ended communist rule and established a multiparty democracy.
- Globular cluster (Wikipedia)
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”.
