Solar Phenomena
This field deflects charged particles from the Sun away from Earth’s equator.
What is Earth’s magnetic field?
The most common element in stars, including the Sun.
What is hydrogen?
The first type of telescopes used by astronomers were these.
What are refractors?
This type of electromagnetic radiation has the highest energy and shortest wavelength.
What are Gamma Rays?
The layer of the Sun from which light is emitted.
What is the photosphere?
This term describes the cooler, darker regions on the Sun's photosphere.
What are sunspots?
A star's color primarily indicates this characteristic.
What is surface temperature?
This type of telescope must be used above Earth's atmosphere to function properly.
What is an X-ray telescope?
This part of the spectrum is visible to the human eye.
What is visible light?
The outermost layer of the Sun’s atmosphere.
What is the corona?
These loops of magnetic field emerge from the Sun’s surface and connect active regions.
What are solar prominences?
A star with very high luminosity but low surface temperature is likely this type of star.
What is a red giant?
The primary function of this instrument is to collect light and bring it to a focus.
What is an astronomical telescope?
This form of electromagnetic radiation is used in cooking and communication.
What are microwaves?
This part of the Sun has the highest density.
What is the sun's core?
The balance between the outward pressure of hot gas and the inward pull of gravity in the Sun is called this.
What is hydrostatic equilibrium?
25% of the Sun is made up of this element
What is Helium?
This type of telescope uses mirrors instead of lenses to gather light.
What is a reflector?
All forms of electromagnetic radiation travel at this speed in a vacuum.
What is the speed of light?
The region of the Sun where energy is transported by the movement of hot plasma.
What is the convection zone?
This process in the Sun’s core converts hydrogen into helium, releasing energy.
What is nuclear fusion?
The term for the sideways motion of a star across the sky.
What is proper motion?
These telescopes detect radio waves from celestial objects.
What are radio telescopes?
This effect causes the observed frequency of a wave to change due to the motion of the source or observer.
What is the Doppler effect?
The balance of forces that keeps the Sun stable is referred to as this.
What is hydrostatic equilibrium?
