Orion nebula photography

Orion is arguably the most spectacular and beautiful constellation in the northern hemisphere. It has many bright stars, which are dazzling and fascinating when observed at night in winter. So today, let's sort out the related pictures of Orion for you through the knowledge of constellations, and let's enjoy the beauty of the universe together.

Orion has a zero-order star, a first-order star, five second-order stars and three third-order stars, which is the brightest constellation of stars. The lineup of Betelgeuse, the sixth in the whole day, and Betelgeuse, the ninth in the whole day, is also extremely strong, winning the 20th and 23rd combinations of the Southern Hemisphere legend Southern Cross, just because Orion's area is much larger than Southern Cross, so it suffers a lot.

For us in the northern hemisphere, Orion is a winter constellation. On a cold winter night, when we look up, it is easy to find Betelgeuse 1-3 arranged in order south of the zenith (the south degree is related to latitude, and the farther north the geographical position is, the lower Orion is).

Around this "Orion belt", there are four bright stars in four directions about the same distance, namely the hunter's shoulders and legs; If conditions are good, you can also see the head of Orion, the sword of Orion, the stick and shield in Orion's hand, and even the legendary Orion nebula.

Betelgeuse is the second bright star in Orion, the tenth brightest star in the night sky except the sun, and the brightest variable star in the sky, with an apparent magnitude of 0. 3 to 1. Second class. This change is irregular, and the short dimming period is about 150-300 days and 5 days. During the 7-year dark period, Betelgeuse was orange-red, the largest and brightest red Supergiant star known, and its diameter was large enough to engulf Jupiter's orbit.

But Betelgeuse has entered the end of the life of a star. According to astronomers' speculation, Betelgeuse will explode into a supernova within one million years, and the explosion of Betelgeuse will last for several months, when it will reach the brightness of the full moon and even the full moon, and it will be visible during the day.

After the eruption, Orion will lose its right shoulder forever, and the winter triangle (an equilateral triangle composed of Betelgeuse, Sirius Canis and Nanhe III) will no longer exist, leaving only one nebula.

Conclusion: Orion occupies a unique position in all civilizations, whether in the east or the west, ancient or modern. For example, the belt of Orion Samsung corresponds to the arrangement of Sanxingdui in ancient China and the pyramids in ancient Egypt, which has attracted countless people's attention for decades. What is the unsolved relationship between Orion and human architecture, alien civilization and earth civilization? The day when the mystery is solved in the future may be the day when the mystery of the universe is uncovered.
