What does the red shift tell scientists?
The redshift tells scientists how fast a star or galaxy is moving away from us.
Are red stars old or new?
The color of a star does not directly determine its age. Red stars are large and a little less hot then the Sun. Scientists can use the color of a star to determine its heat and then using that and its mass determine how old it is.
What color star is hotter a red star of a blue star?
The red star is the coolest and the blue star is the hottest
Is red giant a star or a type of star?
Red giant is a type of star.
Is a blue star smaller than a red star?
It depends on what kind of red star you are referring to. There are red dwarfs and red giants. A blue star is larger than a red dwarf but smaller than a red giant.

How do scientists determine the element present in a star?
By the star's spectrum.
How do scientists use computers to measure distance from stars?
From what I remember in two geology classes, scientists measure the distance between a star and Earth by comparing "red shift," a shifting of certain bands of light toward the "red" end of the spectrum. The further the shifting, the greater the distance.
Do scientist consider a hypothesis to be a fact?
yes scientists consider hypothesis to be a fact
What planet do scientists NOT consider a major planet?
the only planet that scientists do not consider a planet is Pluto, (but they also found new planets in the asteroid belt.)Pluto

Is a blue star smaller than a red star?
