The entire duration of the Sun’s existence (from its formation about 4.6 billion years ago to its future transition into a red giant and then a white dwarf)

The process in a star's core where hydrogen nuclei combine to form helium, releasing vast amounts of energy

The emission of energy as electromagnetic waves (including visible light, which travels from the Sun’s surface through space to reach Earth)

The amount of matter in stars, which determines their life cycles and energy outputs

The stages stars go through from birth to death, which vary based on mass and composition

Any irregular changes that do not follow a pattern or loop (ex. the Sun’s radiation output changes over centuries)

A scientific explanation for the origin of the universe (beginning as a singularity approximately 13.8 billion years ago and has been expanding ever since)

Where light from distant galaxies appears shifted toward the red end of the spectrum, indicating that these galaxies are moving away from us

Where light from distant galaxies appears shifted toward the blue end of the spectrum, indicating that these galaxies are moving toward us

Wave frequency changes as a result of the objects moving toward or away from each other (ex. redshift, blueshift, and ambulance sirens)

The totality of all space, time, matter, and energy that exists (including galaxies, stars, planets, and all forms of matter and radiation)

Cosmic Microwave Background Radiation

The faint glow of radiation left over from the Big Bang (providing strong evidence for the Big Bang theory/expanding universe)

Composition of Matter

The types and proportions of elements and substances that make up the universe (hydrogen and helium are most common)

Electromagnetic Radiation

Energy waves emitted by stars and other celestial objects (including visible light, radio waves, and X-rays)

Relating to the sky, stars, planets, and space

Relating to the Universe (typically does not include Earth)
