This is a stream of light particles.
What is photons?
100
This is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image.
What is a reflecting telescope?
100
These are the dark regions on the photosphere that are caused by lower temperatures.
What are Sunspots?
100
This is a uninterrupted band of color produced produced by an incandescent solid, liquid or gas is what? (An example is light bulb.)
What is continuous spectrum?
100
300,00 km/second
What is the speed of light?
200
The study of the properties of light that depend on wavelength.
What is spectroscopy?
200
This object works by using two lenses to focus the light and make it look like the object is closer to you than it really is.
What is a refracting telescope?
200
Streams of protons and electrons that boil from the corona.
What is Solar Wind?
200
Brief outbursts on the sun that release an enormous amount of energy.
What are solar flares?
200
Numerous relatively small, bright markings on the sun's surface about the size of Texas.
What are granuales?
300
The arrangement of electromagnetic waves according to their wavelengths and frequencies.
What is the electromagnetic spectrum?
300
This is an instrument used to detect radio emissions from the sky and measure the galaxy's distribution of hydrogen, from which stars are formed.
What is a radio telescope?
300
The process of converting hydrogen into helium and producing large amounts of energy.
What is nuclear fusion?
300
A way to tell whether a star is moving toward or away from the Earth.
What is Doppler effect?
300
This is known from a star's spectrum.
Chemical composition.
400
These have the shortest wavelength and highest frequency.
What are gamma rays?
400
These orbit above the Earth's atmosphere and have a clearer vision of space. The first one was put into orbit in 1990 and called this.
What is the Hubble Space Telescope?
400
These are the 4 main parts of the sun.
What are core, photosphere, chromosphere and corona?
400
The effects of solar flares.
What are auroras?
400
The number of sunspots increases and decreases in a cycle of _______________ years
What is 11?
500
Waves with the lowest frequency and longest wavelength.
What are radio waves?
500
A network of several radio telescopes wired together.
What is an Interferometer?
500
Huge cloud-like structures consisting of chromospheric gases.
What are prominences?
500
Produced when visible light is passed through relatively cool gas under low pressure. Radiation from most stars produces this.
What is the absorption spectrum?
500
The halo of color around an object because not all colors can be in focus at the same time. It weakens the image of the stars.
What is chromatic abberation?
