Why is Algol called the Demon Star?

Bottom line: Algol has the nickname the Demon Star because it represents the head of Medusa. This variable star probably intrigued the ancients with its inconstant behavior.

How far away is Algol from the sun?

92.95 light years
Algol/Distance to Earth

How long will Algol last?

Algol is at minimum light for about 20 minutes — as the large, dim star passes across the smaller, brighter one — then it gradually returns to normal.

Is Algol still used?

Despite ALGOL 68-R becoming widely used in (particularly British) military applications for a time, it would take until the 1970s for a full implementation of ALGOL 68 to become available. The last edition of The ALGOL Bulletin was published in 1988, with its editor noting: “ALGOL 68 as a language is very stable.

How far is Algol from Earth?

What type of object is Algol?

Algol is one of the best known variable stars in the sky and a prototype for a class of eclipsing variable stars known as Algol variables. It is a triple star system composed of Beta Persei Aa1, a B-class main sequence star, Beta Persei Aa2, an orange subgiant, and Beta Persei Ab, a dimmer A-class star.

What is Algol used for?

Formerly known as IAL, ALGOL is short for algorithmic language. It is a family of portable programming languages for scientific computations that had a strong influence on other languages. Additionally, ALGOL was used as the standard method for creating algorithms by the ACM in textbooks and academia for over 30 years.

Who made ALGOL?

Alan J. Perlis
ALGOL, computer programming language designed by an international committee of the Association of Computing Machinery (ACM), led by Alan J. Perlis of Carnegie Mellon University, during 1958–60 for publishing algorithms, as well as for doing computations.
