Terms
This is universally true and simple
Law
The red planet
Mars
Name the colors of stars from hottest to coolest
Blue, white, yellow, orange, red
Define galaxy
A collection of stars, gas and dust held together by gravity.
Is not evidence for the big bang:
Cosmic background radiation, Red light shift, magnetic fields, composition of stars
Magnetic fields
This is used to measure the distance to nearby stars
Parallax
This planet has more greenhouse gases than Earth and rotates the opposite direction on its axis compared to the other planets.
Venus
Which stars have the shortest lifespan?
Blue stars
This galaxy type has older stars and little gas or dust
Elliptical
Is not a shape of galaxy:
Spiral, Elliptical, Asymmetrical
Assymetrical
This is a cloud of dust and gas that could form new stars
Nebula
This planet rotates on its side
Uranus
What characteristic of stars determines how the star will end?
Mass of the star
These galaxies have many younger stars and large amounts of gas and dust
Irregular galaxies
Is not able to be observed by astronomers: Visible light, X-rays, composition of stars, distance of stars, Oort cloud, asteroid belt, magnetic fields of planets?
The Oort cloud
These types of planets have hard, rocky surfaces
Terrestrial planets
This planet is 8th from the sun
Neptune
What is the relationship between luminosity and surface temperature in stars?
As surface temperature increases, luminosity also increases.
Our galaxy is a spiral galaxy. What is our galaxy named, and where are we in the spiral?
We are on an arm of the spiral. Our galaxy is the Milky Way.
This device splits visible light into individual wavelengths and can be used to identify the chemical composition of stars
Spectrometer/spectrograph/spectrophotometer
This planet has the least mass of all the planets which has caused it to lose all its atmosphere.
Mercury
Why can a star have a higher apparent magnitude that a star that is more luminous than itself?
If a star is much closer to Earth than the more luminous star, it can appear to be brighter than it is because of the distance.
Can galaxies be part of constellations?
Yes, we can see the andromeda galaxy without a telescope. It is so far away that it looks like a single star, and is part of a famous constellation!
