the cycle of life of a star

A star is a really hot ball of gas, with hydrogen fusing into helium at its core. Stars spend the majority of their lives fusing hydrogen, and when the hydrogen fuel is gone, stars fuse helium into carbon.


Larger stars have more fuel, but they have to burn (fuse) it faster in order to maintain equilibrium. Because thermonuclear fusion occurs at a faster rate in massive stars, large stars use all of their fuel in a shorter length of time. 


This means that bigger is not better with respect to how long a star will live. A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.

Anne Frank

Annelies Marie Frank (12 June 1929 – early March 1945) is one of the most renowned and most discussed Jewish victims of the Holocaust. Acknowledged for the quality of her writing, her diary has become one of the world's most widely read books, and has been the basis for several plays and films.

The Frank family moved from Germany to Amsterdam in 1933, the year the Nazis gained control over Germany. By the beginning of 1940, they were trapped in Amsterdam by the Nazi occupation of the Netherlands. As persecutions of the Jewish population increased in July 1942, the family went into hiding in the hidden rooms of Anne's father, Otto Frank's, office building. After two years, the group was betrayed and transported to concentration camps.

Anne Frank and her sister, Margot, were eventually transferred to the Bergen-Belsen concentration camp, where they both died of typhus in March 1945.
Otto Frank, the only survivor of the family, returned to Amsterdam after the war to find that Anne's diary had been saved, and his efforts led to its publication in 1947.

Anne Frank

On 3 May 1957, a group of citizens, including Otto Frank, established the Anne Frank Stichting in an effort to rescue the Prinsengracht building from demolition and to make it accessible to the public. The Anne Frank House opened on 3 May 1960. It consists of the Opekta warehouse and offices and the Achterhuis, all unfurnished so that visitors can walk freely through the rooms.
