What else can I help you with?
Are blue stars younger than red stars?
Not necessarily. Blue stars are short-lived compared to other stars, so they can never be very old, but a red dwarf star can be any age.
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.
Are red stars the oldest stars?
Red stars are not necessarily the oldest stars. Red stars are low-temperature stars that can be both old and young. The age of a star is determined by various factors, including its mass and chemical composition, rather than just its color.
What are small red stars called?
Small red stars are called red dwarves. They are the least luminescent and coldest stars.
Are red giant stars the largest?
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
Average sized stars will spend their old age as?
Red giant stars.
What are Featureless galaxies containing old red main-sequence stars and red giants called?
If they have red stars including giants in, they can't be all that featureless.
Are blue stars younger than red stars?
Not necessarily. Blue stars are short-lived compared to other stars, so they can never be very old, but a red dwarf star can be any age.

What are featureless galaxies that contain old red main-sequence stars and red giants called?
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
Are red stars the oldest stars?
Red stars are not necessarily the oldest stars. Red stars are low-temperature stars that can be both old and young. The age of a star is determined by various factors, including its mass and chemical composition, rather than just its color.
Is a red star smaller than a regular star?
It depends, as there are two general classes of red star. Red dwarfs are low-mass stars and smallest of all main sequence stars. Red giants and supergiants are old dying stars that are many times larger than other stars.
Nickname American flag?
Old Glory, Star-Spangled Banner, Stars and Stripes
Why do stars turn red when they get old?
because the less mass=less density so it expands and then it turns red.
Are red giants stars the youngest?
No. Unless a star is a red giant (in which case it is old and dying) a red color does not indicate anything about its age.
What are the largest stars?
Blue I think... the hotter and bigger they are they will generally become blue or purple. When it gets old though and basically self destructs it can be red. The largest stars are red stars which are coming to the end of their life cycle
Which is cooler the blue stars or the red stars?
Red stars are cooler than blue stars
