Betelgeuse — will we see a supernova explosion?


Perhaps in the near future, all the inhabitants of planet Earth will witness a very rare event, occurring every few thousand years. According to insiders from Mauna Kea, Hawaii, the red giant Betelgeuse is rapidly changing shape. Over the past 16 years the star has lost a round shape, is rapidly shrinking in the poles, while the star's equator is still held due to the centrifugal force. These are clear signs that still have a few weeks or months before it becomes star in a supernova.


Betelgeuse is also known as the Orion — one of the brightest stars in the familiar constellation of Orion ("Hunter"). As the names of many stars, Betelgeuse is of Arabic origin. The name comes from the phrase "shoulder (or armpit) Hunter" — a place that is the star of the constellation Orion in the figures. Since the star Betelgeuse is a massive red supergiant, it is approaching the end of her life, and soon it will explode as a supernova.



Betelgeuse — a red supergiant, remote from us at 600 light years. The surface of Betelgeuse colder surface of the sun, and its size — 1,000 times more. If you put the star at the center of the solar system, it will fill the space on the orbit of Jupiter. The picture shows a bright strange hot spot on the surface of the star.



How will this rare event from the earth? Suddenly flare up in the sky is very bright star. "Very bright" — means the degree of brightness equal to a minimum of a full moon, as a maximum — full sun. Like last space show about six weeks, which means a half months, "White Nights" in certain parts of the world, other people will enjoy two or three additional hours of daylight and an amazing spectacle of exploding stars at night.

After two to three weeks after the explosion, the star begins to fade, and after a few years — will finally turn to the terrestrial observer in the Crab Nebula type.


But the wave of charged particles after the explosion reach the Earth within a few centuries, and the inhabitants of the earth will have a small (4-5 orders of magnitude less than lethal) dose of ionizing radiation. But do not worry in any case — as the scientists say, the threat to the Earth and its inhabitants not, but such an event in itself is unique — the latest evidence of observations of a supernova explosion in the world dates back to the year 1054.


The word "Betelgeuse" — Arabic origin. The story of its origin is not completely clear, but all experts agree that the second part of the word "elgeyze" is derived from the Arabic "al-Jawzi" (), is the name of the ancient entire constellation of Orion, is the name of the heroine wearing one of the oldest Arabian Nights.

Square "DZHZ" in "Jawzi" means "middle", thus "Jawzi" can be translated as "central." Later, the word "al-Jawzi" was used by Arab astronomers to refer to a single constellations Orion and Gemini. Even now, when Orion is called in Arabic "al-Jabbar" (Giant), the old name may continue to be used.

The most common explanation is a version of the full name of an incorrect translation from Arabic into Latin, the word "poison al-Jawzi" (hand al Jawzi), that is the name of the constellation Orion. The Europeans have mixed Arabic letters Y and B, making Yad-al-Jauza in Bait-al-Jauza (Jawzi house) or even Bat-al-Jauza (armpit Jawzi). So there was a word which gave us this Betelgeuse Betelgeuse.

Thus, it appears that the most common interpretation of the phrase "hand twin" is not quite true. The right thing would be to translate the name as "the hand of the fact that the middle" or "central hand."

It is also interesting ancient Chinese version of the name of Betelgeuse. In Chinese, it looks and sounds like a "piston-Xue-si." So it's not the Chinese no longer chenshe as the "fourth star in the constellation of three stars." Such a paradoxical name came from the fact that the original Chinese astronomy was a "constellation of three stars", that is, the belt of Orion, but later attributed to him a few nearby stars, but the name for the constellation remains the same …
