Galaxy
A huge collection of gas, dust, and billions of stars and their solar systems is held together by gravity.
what is a galaxy?
Orbits the Earth to collect data, transmit and receive signals
What is satellite
The gravitationally bound system of the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.
What is the Solar System?
Objects that orbit the sun between the inner and outer planets
What are asteroids?
What scientists use to describe their observations on how galaxies are expanding. Also, the most widely accepted, scientific theory to explain how the universe formed
What is the big bang theory?
What are the 3 main types of galaxies
What is spiral, elliptical, and irregular?
Placed into space, so that data collected is free from the distortions of Earth
What is space observatory.
Jupiter, Saturn, Uranus, or Neptune
What are gas, giants?
A small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of light.
What is a meteor?
How do you interpret the HR Diagram?
What is by its luminosity and temperature?
What galaxy do we live in?
What is the Milky Way Galaxy?
Can be used in any weather, day or night to collect data from distant objects in space from Earth.
What is radio telescope.
Mercury, Venus, Earth, and Mars
What are terrestrial planets
A meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground
what is a meteorite?
When did the universe begin in an explosion?
What is 13.7 billion years ago?
A type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless image.
What is an elliptical galaxy?
Launched into space to visit places that would be too dangerous for human astronauts
What is space probe?
What is the closest star to earth and its properties?
What is the yellow average star sized SUN?
A small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
What is meteoroid?
the displacement of spectral lines toward longer wavelengths in radiation from distant galaxies and celestial objects.
What is redshift?
In what kind of galaxy is the Milky Way?
What is a Spiral Galaxy?
Which telescope uses lenses and which uses mirrors to focus light and magnify images?
What are refactor telescopes and reflecting telescopes.
What does our Solar system consist of?
What is the Sun, the 8 planets, comets, asteroids, meteors, meteoroids, meteorites, and moons.
Cosmic snowballs of frozen gases, rock and dust that orbit the Sun. When their orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.
What is a comet?
the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.
What is blue shift?
