Reasons for Seasons The Earth’s orbit around the Sun. The tilt of the Earth’s axis at an angle of 23.5 degrees.

Solstice The Sun reaches its greatest distance north or south of the equator twice each year. Each of these days, when the Sun is farthest north or south of the equator, is known as a solstice.

Solstice The day when it is farthest north of the equator is the Summer Solstice. This occurs on June 21 of each year. It is the longest day of the year.

Solstice When the Sun is farthest south of the equator, this is the Winter Solstice. This occurs around December 22.

Equinoxes Halfway between the solstices, neither hemisphere is tilted toward or away from the Sun. The noon Sun is directly above the equator. The Spring Equinox occurs around March 21.

Equinoxes The autumnal equinox occurs around September 22. It marks the beginning of fall.

A giant ball of gases held together by gravity. What is a Star? A giant ball of gases held together by gravity.

A Star is Born! Born in a nebulae – vast clouds of dust and gas in space At 10 million degrees, nuclear fusion occurs A protostar is born https://www.youtube.com/watch?v=ueCXydnpMX4&list=PLqTEqBBPoqwVTbS_6i2lsAmWTaW9312Fl&index=25

Main Sequence After a star forms, it is in its main life period called the main sequence period. This can last for MILIONS of years!

The Death of a Star A star swells up into a glowing red giant that may be a hundred times larger than the original star. What happens next depends on the star’s mass.

The Death of a Star Medium Sized Star Cools off Core collapses Star shrinks White dwarf Black dwarf Giant or Supergiant Star Huge explosion called a supernova Neutron star Black hole https://www.youtube.com/watch?v=cvuygJWiLUE&index=22&list=PLqTEqBBPoqwVTbS_6i2lsAmWTaW9312Fl
