Where all stars are born from interstellar gases and dust that collide together creating more mass due to gravitational pull between particles.
What is a Nebula?
100
A massive collection of nebula and solar systems orbiting around a center bar in spiral, irregular, bar spiral, elliptical, and peculiar shapes.
What is a Galaxy?
100
The inner most part of the sun composed of vast amounts of Hydrogen (H) and Helium (He) where nuclear fusion occurs.
What is the Core?
100
The path the moon takes around the Earth.
What is an orbit?
100
The Earth's motion on it's axis that creates half of the planet covered in sunlight and half of the planet covered in shadow.
What is rotation?
200
The stage of a star in the nebula before it becomes a brightly lit star. It has not gone through ignition stage.
What is Protostar?
200
The Milky Way Galaxy is predicted to eventually collide with this much more massive spiral galaxy in the distant future (billions of years).
What is the Andromeda Galaxy?
200
The violent combining of Hydrogen (H) atoms to make Helium (He) releasing vast amounts of energy in the form of plasma heat and radiation.
What is Nuclear Fusion?
200
The phase of the moon when the face is entirely lit up (shiny) by the sun.
What is a Full Moon?
200
The Earth's complete orbit movement around the Sun in 365 days that is divided into 12 months.
What is revolution?
300
This is the longest cycle of the star and is when the star is most often bright. Our sun is currently at this stage in it's star life cycle.
What is Main Stage or Main Sequence?
300
Special equipment used to detect and measure wavelengths of electromagnetic waves from distance galaxies.
What is the SOHO (Solar and Heliospheric Observatory) Satellite. (satellites aimed out toward space)?
300
The layer of the sun where massive amounts of radiation energy travels through the star from the core.
What is the Radiation Zone.
300
Phase of the moon when the face of the moon is entirely black or in shadow.
What is the New Moon?
300
The movement of the Earth on it's 23.5 degree tilt axis throughout the year creating varying but predictable climate changes.
What is Seasons?
400
Only large mass stars create this phenomenon that spreads interstellar material throughout the galaxy through massive explosion.
What is a Super Nova?
400
Galaxies move through this vast space in predictable patterns.
What is the Universe?
400
The layer of the sun where heat energy travels through liquid plasma causing areas of low heat and areas of high heat.
What is the Convection Zone?
400
The phase of the moon when more than half of the moon face is lit up.
What is a Gibbous Moon?
400
The Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
What is our Solar System?
500
Classification of star's electromagnetic wavelengths creates this diagram delaying the stages, luminosity (brightness), and size (mass) of stars giving us more scientific information on the life cycle of a star. Tools like the Hubble Telescope help provide the data for analysis.
What is the Hertzsprung-Russell Diagram (HR Diagram)?
500
The location of our solar system in the Milky Way Galaxy.
What is the Sagittarius Arm, Orion Spur?
500
The layer of the sun that has massive plasma movements and protrusions visible from Earth. This layer is visible during eclipse.
What is the Corona?
500
The phase of the moon when less than half of the moon is lit up by the sun.
What is a Crescent Moon?
500
The affect of the gravitational pull of the Sun and Moon on the surface water of the Earth creating predictable changes in water depth of the oceans and seas.
