What else can I help you with?
What are the stars located on the left side of the hr diagram like?
They are very hot stars.
Are most stars in the sky hot or cool?
All stars are very hot. Even the comparatively "cool" ones have temperatures of thousands of degrees.
Why are the youngest star are the blue stars?
Only very massive stars are blue. This is because they must burn hotter to resist the crush of gravity due to their large masses. They burn very hot, but also very fast so they have much shorter lifespans than less massive stars do. Therefore, blue stars are young because they become red supergiants and then go supernova fairly rapidly in star lifespan terms. They just do not last very long in the blue giant stage, so those stars, like Rigel in Orion, are young stars. If they were not, they would be red supergiants or neutron stars or black holes by now.
Do hot stars or cold stars live longer?
There is no such thing as a cold star, as even the lowest-temperature stars are very hot. That said, cooler stars last longer as they burn their fuel more slowly.
Very hot stars are a blue-white color?
Yes, very hot stars emit more blue light due to their high temperature. This blue-white color is a characteristic of stars with surface temperatures upwards of 10,000 Kelvin.
What group of stars is very hot but not very bright?
White Dwarf Stars.
How hot are young stars?
It depends on the person like Justin Bieber-VERY but like yeah it all depends on the person lol.
What is a fact about stars?
They are very hot.
How can you tell blue stars are young?
The colour of a star tells you a lot about its temperature and mass. A red dwarf for instance has a low mass and is not very hot whilst blue stars tend to be very hot and quite large. In order for a star to be very hot it must be burning through its supply of fuel more quickly than a cooler star. The faster they burn through their fuel the faster they die and as a result the largest blue stars have a maximum lifetime of only a few million years. Compared with the age of our sun (a few billion years) blue stars are very young.
Are stars very bright if you see one up close?
Yes,Stars are very bright and they are also very hot
Stars are made up very?
hot gases
What are the stars located on the left side of the hr diagram like?
They are very hot stars.
What can you deduce from stars that are hot but not very bright?
That they are distant or small
Are most stars in the sky hot or cool?
All stars are very hot. Even the comparatively "cool" ones have temperatures of thousands of degrees.
How hot can the core of Halley's comet get?
It depends on the color - like how stars work so it would be very very hot!
