Life Cycle of the Sun
The sun is currently and is in what stage?
Main sequence
This type of star explosion is responsible for dispersing elements into space.
supernova
This type of evidence, observed in light spectra, supports the Big Bang theory.
Redshift
This type of light emitted by stars can be analyzed to determine their composition.
spectral analysis
The process that powers the sun, occurring in its core, involves the fusion of hydrogen atoms.
nuclear fusion
Stars are born from a
nebula
The cosmic microwave background radiation is a remnant of this event in the universe's history. (Birth of the universe)
The Big Bang
The motion of galaxies can be observed through this phenomenon, which shows their speed and direction.
Doppler effect
Describe the temperature of a planet based on the distance from the sun.
The closer it is to the sun the hotter it is, the farther away from the sun the colder it is.
The lifecycle of a star ultimately leads to then formation of this type of remnant (remain).
neutron star or black hole
This term describes the movement of distant galaxies away from Earth, indicating an expanding universe.
Hubble's Law
This type of diagram illustrates the relationship between a star's brightness and temperature.
HR Diagram
A the end of its stage the sun will become a what
white dwarf
most stars are composed of
hydrogen and helium
The composition of matter in the universe is primarily made up of these two elements.
hydrogen and helium
This phenomenon occurs when light from distant galaxies is shifted towards the red end of the spectrum. (Moves away from us)
Red shift
This element is primarily produced in the sun's core through nuclear fusion.
Helium
If stars appear red or red shifted it means
they are moving away from us
This theory explains the origin of the universe and the formation of matter and energy.
Big Bang theory
This phenomenon occurs when light from distant galaxies is shifted towards the blue end of the spectrum. (Moves toward us)
Blue shift
