Our Star
The sun is positioned in a spiral arm of this disk-shaped galaxy.
What is the Milky Way?
Light is divided into different ranges, each being a different color of this.
What is a wavelength?
Super-heated ionized matter of the sun's surface that is not classified specifically into solid, liquid, or gas.
What is plasma?
Cooler, small, dark areas appearing on the sun’s surface due to irregularities in the sun's magnetic field.
What are sunspots?
Visible light, ultraviolet rays, gamma rays, x-rays, and radio waves are all examples of this type of energy coming from the sun.
What are electromagnetic waves?
The evolutionary origin of the first supernova cannot explain this.
What is star formation?
This instrument is used to determine the elements in light coming from the sun and stars by studying their wavelengths.
What is a spectroscope?
The visible surface of the sun made up of granules.
What is photosphere?
Severe storms on the sun that emit both rays and particles that affect our satellites, electrical power grids, and communication systems.
What are solar flares?
Power that is generated from the sun for solar-generated electricity and heating
What is solar energy?
The sun has a magnetic field that is greater than the earth’s. True or False
True
The ranges of color which the elements in wavelengths of light from the sun and stars emit.
What is a spectrum?
Masses of hot plasma rising from the sun’s interior to the surface; the size of our largest US states!
What are granules?
A flow of high speed particles from the sun’s corona, mostly protons and electrons, traveling in all directions into space
What is solar wind?
A component that changes radiant energy into power by turning the sun’s light into electric voltage for electricity
What is a photovoltaic cell? (PV cell)
These disturbances in our sun's corona can be either quiescent or eruptive.
What are prominences?
The extremely hot, low-density, and extensive outer portion of the sun’s atmosphere that becomes solar wind
What is the corona?
Jets of plasma coming from the sun’s surface
What are spicules?
Streams of hot material that appear to rise into the corona from the chromosphere. They can be quiescent or eruptive.
What is a prominence?
The layer of the sun above the core where fusion energy travels out from as electromagnetic waves
What is the radiative zone?
These two elements make up 98% of the sun’s mass.
What are hydrogen and helium?
Sun’s temperature is in the middle of the 2 extremes of hot blue stars and cool red stars. In the visible light color spectrum, the sun emits light most strongly where in the spectrum?
What is in the middle of the spectrum for the yellow wavelength of light?
The center of the sun where most of the thermo-nuclear reactions generate the sun’s energy
What is the core?
Large solar flares are called this.
What are coronal mass ejections?
Dramatic changes in this seem to produce sunspots, solar flares, and prominences.
What is the sun's magnetic field?
