They're hotter than the background (about 5 degrees Kelvin) , they must radiate.
The energy is released mainly through radiation, such as visible light.
This involves "nuclear fusion" reactions.
The fusion of Hydrogen into Helium causes heat and radiation to occur.
Long wavelength radiation given out by stars is typically in the form of infrared radiation. This type of radiation has longer wavelengths than visible light and is emitted by stars as a product of their high temperatures. It is important for studying the properties and evolution of stars.
Yes, stars produce electromagnetic waves as a result of nuclear fusion reactions in their cores. The energy released during these reactions causes the stars to emit electromagnetic radiation across various wavelengths, including visible light, ultraviolet light, and X-rays.
Stars can emit various forms of radiation, including ultraviolet, X-rays, and gamma rays. Sun-like stars emit primarily visible light and some ultraviolet radiation. More massive stars can also emit X-rays and gamma rays.
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Not on the Earth.
The gravitational pressure and heat created by gravity causes nuclear fusion to occur in the core of the star. This energy flows through the star to its exterior, where it is radiated into space.
xray radiation and ultraviolet radiation
Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.
The radiation in a nuclear blast comes from the release of energy during the explosion. This energy can create various types of radiation, such as gamma rays, beta particles, and neutrons. The radioactive materials involved in the blast can also contribute to the radiation released.
