The Orion constellation has 81 visible stars, including some of the brightest and most important stars in the night sky. The brightest star in the constellation is Rigel, which is 40,000 times brighter than the sun and emits 100,000 times the energy.

Notes:
The Equator is a line that marks the exact halfway point between the North Pole and the South Pole. On the equator, the length of days changes very little throughout the year. Daylight shines for almost exactly 12 hours, and darkness reigns for almost exactly 12 hours. The further away that one travels from the equator, however, the more variation in length of day that will be observed.

Notes:
The Summer Solstice is the longest day of the year that occurs in the northern hemisphere on 21 June. It occurs when the sun is directly over the Tropic of Cancer, or right over 23.5 degrees north latitude. In contrast, the Southern Hemisphere receives most sunlight on December 21, 22 or 23 when northern hemisphere has its longest nights– or the winter solstice.

Notes:
Solar ultraviolet radiation undergoes absorption and scattering as it passes through the stratospheric layer of the earth’s atmosphere. The ozone layer, a region of Earth’s stratosphere, absorbs 97-99% of the Sun’s ultraviolet (UV) radiation. As a result, no UV radiation at wavelengths shorter than 290 nm reaches the surface of the earth. Which otherwise would potentially damage exposed life forms on the Earth.
