In this part :
Constellation
It is a group of stars that forms a pattern or looks like a certain shape in the sky.
• Constellations appear at different locations in the sky during different times of the year due to Earth's revolution around the Sun, where:
- We can see different constellations in winter than in summer.
- Other constellations that we can't see them in the sky, still exist in the sky as they are not visible from where we are located on Earth.

• Every night, new stars appear from east because the part of night sky we see from a certain place on Earth changes a little bit every night, then after one revolution around the Sun, we will see the same part of night sky again and so on.

Starlight
• Stars make their own light where they are made of hot gases that make them bright.
• Some stars are larger than the Sun while others are smaller than it.
• Planets and moons don't make their own light.
• We, see the moon bright in the sky because it reflects light from the Sun.

Constellations
• Some constellations are always visible in the sky, while other constellations can be seen only during specific seasons.

بالتوفيق
