How do the blue star differ from the red star?
Blue stars are hotter, larger, and more luminous than red stars. They have shorter lifespans due to their high energy output. Red stars are cooler, smaller, and less luminous, and they have longer lifespans.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
One star is reddish and another is bluish Do you know anything about the relative temperatures of the two stars?
The reddish star is likely cooler than the bluish star. Red stars have lower surface temperatures compared to blue stars, with blue stars being hotter and more luminous. The color of a star is indicative of its temperature, with cooler stars appearing reddish and hotter stars appearing bluish.
Do blue stars and red giant stars have similar brightness values?
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
Why is it difficult to find out how common the most luminous stars are The least luminous stars?
from my text book: "The most luminous stars are so rare you find few in your survey region. There are no O stars at all within 62 PC of Earth. Lower-main-sequence M stars, called red dwarfs, and white dwarfs are so faint they are hard to locate even when they are only a few parsecs from earth."

What is the Collective noun for an irregular luminous band of stars?
An irregular luminous band of stars is called a galaxyof stars.
Are the stars and moon luminous?
Stars are luminous, shine by themseves. Moon isn't, it can only reflect light.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Which is cooler the blue stars or the red stars?
Red stars are cooler than blue stars
What color are very heavy stars?
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.
Are stars luminescent?
Strictly speaking, no; stars are incandescent (light resulting from heat) as opposed to luminscent (light resulting from non-thermal based effects). One might, however, safely describe stars as "luminous" in a metaporical sense.
Stars are brilliant balls of gases that are?
luminous
Are stars luminous or non luminous?
All things, except black holes, are luminous. That includes stars. You might think that some other things are not luminous but that's because you can't see the kinds of light that they emit.
Are all nebulae luminous?
Technically, no nebulae are luminous. The ones that appear as such have stars either within or near them, and the nebulae merely reflect the light emitted by these stars.
A name for a luminous object?
sun, stars, CD,
What are the stars?
A star is a massive, luminous ball of plasma.
