What do we call a large family of millions of stars?
Red giants. By the way, what if it was a white star.
What are some physical characteristics of quasars?
They're elliptical shaped and the typically have a red center because of all the red giants that form in this type of galaxy.
Are blue giants and red dwarfs alike?
Blue giants and red dwarfs are both types of stars, but they are quite different. Blue giants are massive and hot stars that shine brightly, while red dwarfs are smaller, cooler stars that emit a fainter light. Blue giants are more short-lived and evolve faster compared to red dwarfs, which have much longer lifespans.
How do red giants form?
A star might begin to die after its main sequence. It'll balloon to a very big size. They're called red giants because the star is big and red. A red giant can die, though. Red giants die when their surface sheds into a cloud called a planetary nebula. Its core becomes a white dwarf. Our sun will go through this path.
What are Large stars that are bright but not hot are called?
They are red giants.
What do all stars eventually turn into?
All stars eventually turn into Red Giants or Super Giants
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.
Which are hotter white dwarfs or red giants?
red giants
Are there different types of red giants?
Yes, there are. The classic red giants that come from sun- like stars, and red supergiants come from blue giants.
Are red giants or blue giants bigger?
Generally red giants are bigger, but really it has more to do with how hot they burn. Blue giants burn hotter and have more mass.
How big are Red Giants?
Red Giants are 20 to 100 times bigger than the Sun.
Which of these stars produces the most light?
Well light wise the highest category would be blue giants, red giants, and super red giants.
Who stated the universe is expanding?
The Doppler effect is well known, and Fizeau observed the red-shift of the light from distant stars. So the effect was called Doppler-Fizeau. There are a class of astronomic objects called the Cepheid Variables in which it is observed that the rate of variation in the brightness of the star related to its absolute brightness, and therefore its mass. Thus these stars can be used as a measure of distance, as the period of their variability does not change with distance, but their apparent brightness and their red-shift does. Hubble made a number of observations of Cepheids in the Andromeda galaxy. The article on Cepheid Variables in wikipedia.org is well worth reading, as it illustrates scientific discovery and enquiry. He went on to reason that the Cepheids could be used as a standard measure of astronomical distance. And this formed the basis of the Expanding Universe. These observations are one of the foundations of cosmology.

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.
New York Giants red jerseys?
Yes, Giants alternate jerseys or pracitce QB jerseys are red.
Where are white dwarfs supeegiants and red giants?
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
