Constellation

• Movement over time.

• A group of stars which form a recognizable pattern and given a specific name.

• Each of the two halves of the Earth; divided by the equator (Northern and Southern).

• A huge sphere of very hot, glowing gas.

• In Winter, stars appear brighter. This is primarily because:

• • There are fewer stars in the sky, and those that are visible, generally appear brighter. This is because the Northern hemisphere has rotated away from the galaxy’s center.

• • The cooler temperature means the air cannot hold as much moisture as it can in summer, so the sky appears clearer and the stars more visible. 

• Winter nights tend to be darker and longer, making stars easier to see.

• This is because the Northern hemisphere has rotated toward the galaxy’s center.

In Summer, the Earth has rotated, angling toward the galaxy’s center, so:

• has a view of the combined light of billions of stars

• • individual stars appear less bright.

• There are fewer stars in the sky

• warmer temperature means the air cannot hold as much moisture
