Algol spotted the secret of 'Devil Star' Algol blinked off randomly

Evidence from the Cairo calendar has shown that the ancient Egyptians soon discovered "Devil stars" more than 92 thousand light-years away from us.

Algol is one of the metamorphic (altered stars ) of the constellation Perseus, more than 92 thousand light-years away. This is a typical example of a two-star model that surrounds a center, with a constant light and dark time.

The two stars revolve around each other, creating an interesting turn of lightning.

Algo was originally discovered by the ancient Greeks about 3,000 years ago. However, the ancient Greeks did not understand this star clearly and thought it was "Devil's Star" because of its flashing.

Star Algol is linked to the gods in the Cairo calendar.

Recently, researchers at the University of Helsinki (Finland) have discovered that the star was discovered by the ancient Egyptians during the same time period, but with very clear awareness of Algol's lightning cycle. .

According to Lauri Jetsu and Sebastian Porceddu from University of Helsinki, there is evidence that Algol is related to the Cairo calendar gods (Cairo Calendar - CC - from 1244 to 1163 BC).

Ancient script about Cairo calendar.

Specifically, the flashing cycle of the star Algol (2.85 days) and the Moon (29.6 days) is really strongly related to the gods inside this calendar. Jetsu said: "The evidence shows that the lucky forecast period of 2.85 days in the CC calendar is equal to that of the Algol starlight cycle in history."

Although still controversial, Jetsu and Porceddu say that their analysis is the most comprehensive compared to previous studies. In addition, it contributes to reinforcing the notion that Cairo calendar is the oldest historical text about "variable star" stars.

The study is published in Plos One magazine.
