Blue Stars are the hottest there is. Stars are classified according to a mnemonic category - O,B,A,F,G,K,M.
O being the the hottest (blue stars) and M being the coolest (Red Dwarfs).
The star around planet Earth belongs to Category G - a bright and fairly young Yellow star, although it tends to fall more towards the Orange spectrum. It is thus no longer a true Category G star and is rechristened according to the Morgan-Keenan System as Category G2V based on the luminosity.
Red stars emit about 5% of the radiation of Earth's sun (thus bringing the probability of harboring habitable planets in their solar systems down to sub zero levels). However frequent "flare ups" do occur due to the high level of magnetic activity.
Perhaps it would be easier for you to understand if I just say that Earth's Sun has a luminosity level of 0.6 to 1.5 (on the hottest of days), whereas Blue stars have levels well beyond 30,000 (that would make it at least a million times brighter than Earth's Sun). Naturally, its much larger than Earth's sun (nearly 16 times as big). These are the Hypergiants and the rarest among all the stars as they tend to burn up the hydrogen at their cores very quickly and go hypernova (thats umm what the super-supernova is called).
What else can I help you with?
What is the temperature of blue light?
Blue light itself does not have a temperature because it is a form of electromagnetic radiation, not a physical object. Temperature is a property of matter, such as a light bulb or a star, that emits blue light.
What is the surface temperature of alkaid?
Alkaid, a star in the constellation Ursa Major, has a surface temperature of around 7,500 degrees Celsius. It is a hot, blue-white star that emits a significant amount of ultraviolet radiation.
What color star is regulus?
the color of the star regulus is blue-white
How does the color indicate the temperature of a star?
The color of a star indicates its temperature based on the peak of its blackbody radiation curve. Hotter stars appear blue or white because they emit more energy in shorter wavelengths, while cooler stars appear red because they emit more energy in longer wavelengths. The relationship between a star's color and temperature is known as Wien's law.
What really is a blue star?
A blue star is a type of star that is hot, massive, and emits predominantly blue light. These stars have temperatures of around 10,000 to 40,000 degrees Celsius, causing them to appear blue in color. Blue stars are typically young and have short lifespans compared to other types of stars.
What is the range of electromagnetic radiation produced by a star?
That will depend a lot on the star's temperature. The highest frequencies can be infrared radiation, red light, blue light, ultraviolet, or even x-rays - all depending on the star's surface temperature.
What is the temperature of blue light?
Blue light itself does not have a temperature because it is a form of electromagnetic radiation, not a physical object. Temperature is a property of matter, such as a light bulb or a star, that emits blue light.
What form of radiation is released from the star?
Infrared radiation.
Light from a star is a form of?
Electromagnetic radiation.
Why is sky blue what does radiation have to do with it?
Why is sky blue
Is the blue or red star hot?
The blue star is the hottest star.
How would the color of a star affect how life on a planet in its system might perceive colors?
I would assume that beings in such a system would not have developed the ability to see frequencies of the electromagnetic spectrum that are not naturally available to them. For example, beings in a system whose star is pure yellow probably would not have developed the ability to see blue, since you need blue light in order to see blue, and yellow light doesn't have any (white light - blue light = yellow light). Another answer: I think that they would be able to see colors like we can, albeit in different hues because we have a yellow star, and yet we can see red, blue, etc. I think that if they lived in a system with a blue star, then their white point would appear a little more blue in comparison to ours. The same theory applies to other color/radiation level star systems.
What is the definition of a blue star?
A star that has a blue color!
What star has a higher surface temperature blue star or a red star?
Blue.
Where and what is the hidden object on cute animal quiz?
It is the blue star on level 5, but click it fast, it will disappear in time.
Why is the sun red and not blue like gas?
The Sun is not red. Its radiation is most intense in the yellow-green part of the spectrum, which is why it is called a "yellow dwarf" star.
What can be said about a red star and a blue star?
A red star is cool whereas a blue star is hot.
