Nova

A nova (plural novae or novas) is a cataclysmic nuclear explosion on a white dwarf, which causes a sudden brightening of the star. Novae are not to be confused with other brightening phenomena such as supernovae or luminous red novae. Novae are thought to occur on the surface of a white dwarf in a binary system when they are sufficiently near to one another, allowing material (mostly hydrogen) to be pulled from the companion star's surface onto the white dwarf. The nova is the result of the rapid fusion of the accreted hydrogen on the surface of the star, commencing a runaway fusion reaction.

Development

The development begins with two main sequence stars in a binary relation. One of the two evolves into a red giant leaving its remnant white dwarf core in orbit with the remaining star. The second star—which may be either a main sequence star, or an aging giant one as well—begins to shed its envelope onto its white dwarf companion when it overflows its Roche lobe. As a result, the white dwarf will steadily accrete matter from the companion's outer atmosphere; the white dwarf consists of degenerate matter, so the accreted hydrogen does not inflate as its temperature increases. Rapid, uncontrolled fusion occurs when the temperature of this accreted layer reaches ~20 million kelvin, initiating a burn via the CNO cycle.

Vespers

Vespers is the sunset evening prayer service in the Orthodox, Western and Eastern Catholic, Anglican, and Lutheran liturgies of the canonical hours. The word comes from the Greek ἑσπέρα ("hespera") and the Latin vesper, meaning "evening". It is also referred to in the Anglican tradition as evening prayer or evensong. The term is also used in some Protestant denominations (such as the Presbyterian Church and Seventh-day Adventists) to describe evening services.

Current use

Roman Rite Catholic

Vespers, also called Evening Prayer, takes place as dusk begins to fall. Evening Prayer gives thanks for the day just past and makes an evening sacrifice of praise to God (Psalm 141:1).

The general structure of the Roman Rite Catholic service of vespers is as follows:

High school

A high school (also secondary school, senior school, secondary college) is a school that provides adolescents with part or all of their secondary education. It may come after primary school or middle school and be followed by higher education or vocational training.

Terminology

The term "high school" originated in Scotland, with the world's oldest high school being Edinburgh's Royal High School from 1505. The Royal High School was used as a model for the first public high school in the United States, Boston Latin School founded in Boston, Massachusetts.

The precise stage of schooling provided by a high school differs from country to country, and may vary within the same jurisdiction. In all of New Zealand and Malaysia, along with most of Britain and parts of Australia, Bangladesh and Canada, high school means the same thing as secondary school, but instead of starting in 9th grade, these "secondary schools" begin at ages 11 or 12.

Country by country

Australia

In Australia, high school is a secondary school, from Year 7 or Year 8 through to Year 12, varying from state to state. High school immediately follows primary (elementary) school; therefore, a Year-7 Australian high-school student is sometimes as young as 12. In Tasmania and the Australian Capital Territory, the term "high school" generally refers to Years 7–10, whereas the term "College" is used for Years 11–12. In Victoria the term "secondary college" has largely replaced the term "high school" following the reforms of the Labor Government in the late 1980s and early 1990s. Some schools have retained the name "high school" (such as Melbourne High School) and many have now dropped the "secondary" and are simply known as "college".

Chicopee High School

Chicopee High School (CHS) is a public high school located in Chicopee, Massachusetts, United States. It serves students in grades 9 through 12. Its official school colors are maroon and gold. Its mascot is the "Pacer."

History

CHS was the third high school in Chicopee. Until 1896, two smaller high schools served Chicopee and Chicopee Falls. These were replaced by Central High School which opened in 1890 and served as the only high school until it was destroyed by fire in January 1916. The Taylor School in Chicopee Falls served as a temporary high school until 1921.

To be located at 650 Front Street, construction on a new Chicopee High School began in 1917 on land once occupied by the Assumption Church which itself had been destroyed by fire in 1912. Construction on the $1 million school was delayed by World War I, and CHS finally opened in September 1921. It was built in the collegiate style and faced with tapestry brick. Situated on a hill, its large front lawn featured the "keys of knowledge" outlined in shrubs. A small park and a memorial to Chicopee residents who died in WWI was constructed on an adjacent parcel.
