APOD: 2017 June 4 Orion: Belt, Flame, and Horsehead

Though the time frame fit around the time of the visit of the Three Wise Men, experts from other places did not note the appearance, so it was not that bright. When King Herod heard about this, he became worried that someone will become a new king. He called the chief priests and scribes of his kingdom and asked them about the newborn king. The priests said that the baby is in Bethlehem of Judea, as it was in the prophecy. Upon knowing about this, King Herod called the three Wise Men and asked about the star that they were following. He told the wise men to bring him the word when they have found the child so that he can also pay homage to the new king.
For observers in the southern hemisphere, the hourglass figure of Orion appears upside down. In January, Orion’s Belt appears high in the northeastern sky, parallel to the horizon, around 10 pm. By April, it moves to the northwest and sets earlier in the evening, appearing perpendicular to the horizon.

  • A nova is a new star that can appear very bright in the night sky.
  • The three stars have traditionally been interpreted astrologically as a unit.
  • The priests said that the baby is in Bethlehem of Judea, as it was in the prophecy.
  • It has played a central role in astral navigation in the Northern hemisphere since prehistoric times.
  • Some people call it the Dog Star because it is in the constellation of Canis Major.

He dialed to the time in the Age of Leo, basing to the structure of the Sphinx, and found the exact alignment in 10500BC. One of the most fascinating mysteries related to Orion’s Belt is the Pyramids of Giza. This idea was popularized by Robert Bauval in the Orion Correlation Theory.

  • For northern observers, they never appear in the northern sky, nor do they appear above the southern horizon for observers in the southern hemisphere.
  • It’s a distinctive three stars of a similar brightness in a line, and they really stand out as part of that kind of box that makes up the constellation Orion itself.
  • Below the three bright stars of Orion’s belt lies his sword, where you can find the famous Orion Nebula.
  • The cluster has several dozen members bright enough to be seen through a telescope.
  • It is one of the brightest stars in the night sky and can be easily found with the naked eye.
  • It is estimated that Alnilam will turn into a red supergiant and explode within the next million years.

Taurus: the Bull Constellation

We can see it during the winter months in the northern latitudes, from about November to February. During that time, the season in the Southern Hemisphere is summer. Observers from the south of the equator can see Orion’s Belt during summer months. From anywhere on Earth, the best time to see the Celestial Hunter’s Belt is at 9 pm during the first month of the year, in January. Chances are excellent that if you can’t yet picture what Orion looks like, you’ll have an „aha!” moment once you lay eyes on either a star chart or the real thing.

Where is the Orion constellation in the sky?

Continue from Orion’s Belt drawing a straight line until you reach a bright star — that’s Sirus. In Western culture, you may sometimes hear Orion’s Belt referred to as the Three Kings in a biblical reference or the three sisters. In Chinese mythology, Orion’s Belt goes by The Weighing Beam. Two books of the Bible — the Book of Job and the Book of Amos — mention Orion’s Belt, along with another well-known asterism, the Pleiades.

How far apart are the stars in Orion’s Belt?

It is a direct reference to the biblical tale of the three kings who offered gifts to the baby Christ. Alnitak is a triple star system, Alnilam is 375,000 times brighter than the Sun and Mintaka is a binary star system (two stars orbiting each other). In ancient Egyptian mythology, the stars in Orion’s Belt represented the resting place of the soul of Osiris, the Egyptian god of the deceased. There is even a theory, proposed since the late 20th century, that the ancient Egyptians positioned the pyramids of Giza to align with the stars in Orion’s Belt roughly 4,500 years ago.

Orion and Orion’s Belt in Cultures

Aldebaran the brightest star in the constellation of Taurus the Bull. We can find this red star if we draw a line connecting Orion’s Belt and extending it to the side of Mintaka. There are about 6,000 in the night sky that are visible to the naked eye but only 58 are selected. Two of these stars orbit each other and the third component orbits the pair. It only takes 5.7 days for the first two stars to orbit around one another because they are close. Since these stars orbit each other, there will be times when one passes in front of the other and covers it from our line of sight here on Earth.
A line drawn through the Belt stars to the northwest leads to Aldebaran, the luminary of the constellation Taurus and the 14th brightest star in sky. Aldebaran appears as a member of the V-shaped Hyades cluster, which outlines the head of the Bull, but is much closer to us than the cluster. Rigel is also a young star, estimated to be 8 million years old. Like Betelgeuse, Rigel is much larger and heavier than our Sun.

Constellations near Orion’s Belt

It shines at magnitude 6.85 and consists of Orion’s Bet a spectroscopic binary pair. The two components orbit each other with a period of about 30 days. Even though it is a young star, Alnilam is already approaching the end of its life.

In the Southern Hemisphere, it will be high above the northern horizon — Massey. During the winter months, Orion’s Belt and the Big Dipper are both prominent in the night sky. The constellations appear in different parts of the sky, with the bright Gemini and the faint Lynx between them. A line extended through the Big Dipper’s bowl leads to Castor, the second brightest star in Gemini. The brighter Pollux is part of the Winter Circle, a large hexagonal asterism also formed by Capella in Auriga, Aldebaran in Taurus, Rigel in Orion, Sirius in Canis Major, and Procyon in Canis Minor.
