"In the Starry Sky (1)" Universe PPT Courseware

Think: What is a constellation?

Constellations: In order to facilitate identification, people grouped the seemingly motionless stars into groups, divided the entire sky into 88 different areas, and named them. These areas are called constellations.

The origin of the constellations:

In 1928, the International Astronomical Union decided to divide the entire sky into 88 star areas, called constellations. The names of the constellations are shapes composed of bright stars, combined with mythological stories, and named with characters, animals and appliances. These 88 constellations are of different sizes and shapes. The largest constellation is Hydra, which spans 102° from east to west.

Let’s build a “constellation” model

1. Open the lid of the box, spread the lid and bottom of the box flat on the table.

2. Insert the seven steel rods with small balls on the top into the holes numbered 2, 7, 1, 3, 4, 5, and 6 in order from long to short.

3. Look at these seven stars from any angle.

Let’s take a look again:

The main symbols of the Lyra and Aquila constellations are Altair and Vega respectively. How can we find Cowherd and Vega?

There is a shining band of light in the sky, which is often called the "Milky Way". We search according to this light belt. To the east of the "river" is the Cowherd, to the west of the "river" is the Weaver Girl, and in the middle of the "river" is Deneb. The four not-so-bright stars next to the Weaver Girl are the heavenly soldiers escorting the Weaver Girl; The two stars next to it are his two children in the basket; the Milky Way is the river that separates them.

What I found:

Deneb, Vega and Altair are the famous bright stars in the summer sky, forming a triangle known as the "Summer Triangle". If you find them, you will also find the three constellations of Lyra, Swan and Aquila.

Scorpio is shaped like a scorpion, and its main symbol is Antares, also known as the Great Mars, which is a dazzling red star.

The distance between the planets that make up the constellation remains unchanged and they are three-dimensional to each other.

The shapes we see are only the shapes we see on Earth.

The same constellation looks different from different locations in space.

1. Constellations are (visual images) of (different distances) and (no connection) stars in the sky. Graph (different) if viewed from different angles

2. The Big Dipper is the main symbol of the Ursa Major constellation.

3. The figure formed by (bright stars) is the main symbol of the constellation.

4. Three bright stars on summer nights form a huge triangle called the Summer Triangle. They are Deneb, Vega and Altair.

2. Connect: Connect the stars with their constellations.

Altair Lyra

Deneb Scorpio

Vega Aquila

Antares Cygnus
