It's the radiation from distant bodies throughout the univers that scientists study. It consists of electric and magnetic disturbances traveling through space.
Electromagnetic Radiation
These craters on the Moon formed when objects from space crashed into the lunar surface.
Impact craters
He formulated the heliocentric model of the solar system.
Nicolas Copernicus
It's the layer of the Sun's atmosphere that is approximately 2500 km thick and has an average temperature of 15,000 K.
Chromosphere
Evidence of the Big Bang, its a shift in spectral lines that are shifted toward longer wavelengths indicating stars are moving away from the observer.
Red Shift
All types of electromagnetic radiation, arranged according to wavelength and frequency.
Electromagnetic spectrum
The state at which the Moon's orbital and rotational periods are equal.
Synchronous rotation
Kepler's first law demonstrates that each planet has an elliptical orbit of unique size and shape with this celestial body at one focus.
The Sun
It determines the wavelength of energy each layer of the Sun emits.
Temperature
Its the formulaic method of representing the epansion of the universe.
The Hubble Constant
It's the distance between peaks on a wave.
Wavelength
The length of time it takes for the Moon to go through a complete cycle of phases.
Lunar month
Galileo's discover of this planet's moons prved that not all celestial bodies orbit Earth.
Jupiter
It drives solar activity such as fountains and loops of glowing gas.
Magnetic field
They are known as the terrestrial planets
Mercury, Venus, Earth, Mars
The type of telescope that uses lenses to focus visible light.
Refracting telescope
At only about 12%, this is the term used to describe the incoming sunlight that the Moon's surface reflects.
Albedo
His first law of planetary motion states that each planet orbits the Sun in the shape of an ellipse rather than a circle.
Johanas Kepler
This is an arc of gas that is ejected from the chromosphere.
Prominence
Along with Hubble's discovery of the expansion of the universe, this type of radiation that interferes with radio waves, this leftover radiation from the Big Bang supports the occurrence of the event.
Cosmic Background Radiation
The technique that uses the images from several telesopes to produce a single image.
Interferometry
It's the order of the Moon's phases beginning with New Moon
Waxing crescent, first quarter moon, waxing gibbous, full moon, waning gibbous, 3rd quarter moon and waning crescent
Newton determined that each planet orbits a point between it and the Sun called this.
Center mass
In the inner portion of the Sun, extending to about 86% of its radius, this is the method of energy transfer.
Radiation
They are the layers of the atmosphere, in order, beginning with the layer closest to the Earth's surface.
Troposphere, stratosphere, mesosphere, thermosphere, exosphere
