|
|
A group of stars
What is a star cluster?
|
False.
We can only see two of the three dimensions
True or False?
We can see all three of the three dimensions of a elliptical galaxy. |
Hydrogen and helium
What are the two most abundant elements that makes a star?
|
Main sequence star, Red Giant Stars, White Dwarfs, Neutron Stars, Black Holes, Brown Dwarfs, and Variable Stars
Name all the types of stars.
|
Nuclear fusion is the process in
which light atoms combine to form heavier atoms, giving off excess energy in the process
What does nuclear fusion do?
|
|
Three or more stars bound by gravity that or bit each other
What is a star system?
|
Look like oval shaped disks and appears as a circular bright light
What does elliptical galaxies look like?
|
The Big Bang
Where did hydrogen come from to form the stars?
|
False
FalseTrue or False
High mass stars live longer than low mass stars. |
The temperature of the core
There are a number of different ways for nuclear fusion to occur in stars. What in the core makes the combinations of ways of nuclear fusion?
|
|
Objects in orbit around a star
What is a planetary system?
|
Bulge, disk, and halo
What are the main components of a spiral galaxy?
|
The extremely cold temperatures in space causing the elements to become more dense and making them bind together
What makes the elements clump together in the universe?
|
Main sequence star
What type of star is our sun?
|
They are created once nuclear fusion has occurred at the core of the star
How are main sequence stars created?
|
|
Clusters of multiple galaxies
What is galaxy groups?
|
They have no regular symmetrical structure
What doesn't irregular galaxies have?
|
Nebula, protostar, nuclear fusion, main sequence, red giant, and white dwarf
What are the stages of a sun like star?
|
A small very dense star, formed when it exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula
What is a White Dwarf?
|
When a star like our sun, or one larger, runs out of its
hydrogen fuel
When is a Red Giant Star created?
