the inner layers are very cool, the outer layers are somewhat cool
:9 true
In a star, energy is primarily transferred through radiation in the outer layers and through convection in the inner layers. In the core, where nuclear fusion occurs, energy is generated and eventually travels outward through the layers by radiation, heating up the outer layers.
The true name for the North-Star is Polaris.
True. At the center of the star is a hub, or a switch.
Where did you get that idea from?!
Yes you can. I have tried it. Just simply add layers over. I hope I helped. From Bollywood Star
When the outer layers of a star cool, it typically becomes a red giant or a supergiant, depending on its initial mass. As the star expands and its temperature decreases, it emits light primarily in the red spectrum. Eventually, it may shed its outer layers, leaving behind a hot core that can become a white dwarf, neutron star, or even a black hole, depending on the star's mass. The cooling process marks the later stages of stellar evolution, ultimately leading to the star's death.
The star will blow out its outer layers in a huge explosion called a supernova.
True.
A true aneurysm is an expansion of all the the layers of an arterial wall as compared to a pseudoaneurysm which is a dilation of an artery with actual disruption of one or more layers of its walls, rather than with expansion of all wall layers. Also called false aneurysm.
It is called a nova.
The inside of a star consists of different layers, including a core where nuclear fusion reactions occur. As you move outward from the core, you encounter layers of hydrogen and helium undergoing fusion, followed by layers of gases in different states due to temperature and pressure variations. The outermost layer is the star's atmosphere, where gases are less dense and extend into space.
