Big Bang Theory

Group of stars that forms a pattern in the sky that looks like a familiar object, animal or character.

• Star
• Constellation
• Cluster
• Galaxy

Measure of the amount of light a star actually gives off.

• Absolute Magnitude
• Apparent Magnitude
• Cluster 
• Big Bang Theory

Measure of the amount of light from a star that is received on Earth.

• Absolute Magnitude
• Apparent Magnitude
• Fusion
• Red Shift

Unit representing the distance light travels in one year, used to record distances between stars and galaxies.

• Spiral Galaxies
• Nebula
• Light-Year
• White Dwarf

Lowest layer of the Sun’s atmosphere; gives off light and has temperatures of about 6,000 k. 

• Corona
• Chromosphere
• Photosphere
• Nebula 

Layer of the Sun’s atmosphere above the photosphere. 

• Corona
• Chromosphere
• Sunspot
• Black Hole

Outermost, largest layer of the Sun’s atmosphere; extends millions of kilometers into space and has temperatures up to 2 million 

• Corona
• Sunspot
• Light-Year
• Photosphere

Areas on the Sun’s surface that are cooler and less bright than surrounding areas, are caused by the Sun’s magnetic field, and occur in cycles. 

• Nebula
• Sunspots
• Corona
• Photosphere

Large cloud of gas and dust that contracts under gravitational force and breaks apart into smaller pieces, each of which might collapse to form a star. 

• Cluster
• Big Bang Theory
• Nebula
• Red Shift 

Late stage in the life of comparatively low-mass main sequence star in which hydrogen in the core is deleted, the core contracts and temperatures inside the star increase, causing its outer layers to expand and cool. 

•  Nebula 
• Main Sequence Star
• White Dwarf
• Red Giant
