What is the role of the Hubble space telescope
What is to take images of space outside of earth's atmosphere
What is the main role of constellations
What is help navigate the land and sea
What is the difference between a stars apparent magnitude, and its absolute magnitude
What is apparent is how bright it appears from earth while absolute is how bright the star actually is
What is a lightyear?
What is a measure of distance. The distance light can travel in a year
About how long does it take for light to travel from the sun to the earth?
What is approximately 8 minutes
What is the nearest star to earth? Besides the sun
What is Proxima Centauri
How do stars move?
They orbit around the galaxy they are in. Likely held in by gravity.
Which stars tend to be hotter, and which tend to be cooler
What is large stars tend to burn hotter and quicker, smaller burn cooler and for longer
Supergiant
A star with a diameter more than 100 times the sun
Largest type of galaxies
What are elliptical galaxies
The dream team that is never up to a bad scheme who wear jeans that look super lean while eating a can of beans from a bowl they recently cleaned(They are good at baseball)
Cubs who are Chicago
Red Shift
The tendency of light waves to stretch as they travel through space, making them appear more red.
How do stars 1/10 the sun die?
What is they slowly burn out.
Science that explains how the universe began and how it has changed over time
What is cosmology
When two stars appear close an actually revolve around one another
What are binary stars
What is a cepheid variable?
What is a star whose brightness changes as it expands and contracts
Parallax
Changes in position of a distant object as one’s viewing position changes
What did the big bang correctly predict that relates to red shift?
What is that the universe is constantly expanding and stretching
Explain how we know black holes exist
What is, we can not see them, but we can see their effects on space around them
Why did people assume the universe was older when they found out that light does not travel instantly?
What is, it had to take time for the light from far away to make it to the earth
Explain what dark matter is
What is a hypothetical material that has mass, but is not currently observable. Helps explain the lack of mass seen in the galaxy
How do stars about the size of the sun die?
What is they start burning helium instead, Expand and become a red giant. collapse and become a white dwarf, cools and becomes a black dwarf
Summarize the time slowed by gravity theory
What is gravity can affect how time passes. Intense amounts of gravity can slow down time
What is the issue with the light created in transit theory?
What is objects further than 7,000 lightyears away can not come from real events
How do stars 8 times larger than the sun die?
What is they get so hot they explode into a supernova, this can usually leave behind a white dwarf, that white dwarf will become a neutron star, or a black hole based on its mass
