Yes. Stars prouduce light as a product of nuclear fusion.

How is the age of the galaxy determined?
The age of a galaxy is determined by studying the oldest stars within it using methods like measuring the radioactive decay of elements, analyzing the chemical composition of stars, and calculating the expansion rate of the universe. By combining these techniques, astronomers can estimate the age of galaxies in the universe.
How old is te sun thought to be?
The Sun is estimated to be about 4.6 billion years old. Scientists determine its age by studying the life cycle of stars, radioactive dating of meteorites, and the formation of the Solar System.
How do you know if a meteor is radioactive?
Meteors are typically not radioactive as they are composed of various elements and minerals found in space. However, if a meteorite were to contain radioactive materials, it would need to be tested using specialized equipment to detect radiation levels.
Where argon came from?
Argon was primarily formed in the Earth's mantle through radioactive decay of potassium. It is also produced in stars through nuclear fusion processes. Argon is one of the noble gases and is the third most abundant gas in Earth's atmosphere.
Is space junk radioactive?
Not all space junk is radioactive. Space debris can consist of defunct satellites, spent rocket stages, or fragments from previous space missions, which may or may not contain radioactive material depending on their original purpose. However, precautions are taken when handling or encountering space junk to ensure safety.
What process provides the heat?
Three processes produce heat. Contraction, in both stars and planets; radioactive decay, in planets, and nuclear fusion, in stars.
What planets and celestial bodies seem to be radioactive?
Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things. Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.
Where in ntature does nuclear reaction occur?
In the interior of stars, where matter is at an extreme temperature and pressure. Also, wherever there are radioactive isotopes - for example, on Earth - these will gradually decay.
Are radioactive elements made in a laboratory?
What an interesting question. The answer is however complex.It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way.(Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements)However, making a radioactive element or isotope from scratch requires the application of an enormous amount of energy. The place where all elements heavier than the element Iron (Fe - Atomic number 26) are made is in stellar explosions, the death of stars 8 or more times more massive than our Sun, called "supernovas".It is in supernova explosions that the radioactive elements are made.
What do you spell radioactive?
"Radioactive."
Is the element sodium radioactive or non-radioactive?
non radioactive element
How are nitrogen oxygen and argon formed?
Nitrogen, oxygen, and argon are formed through various processes in the universe. Nitrogen mostly originates from the fusion of carbon and helium in stars, while oxygen is primarily formed during the later stages of stellar evolution through nucleosynthesis processes. Argon is mainly produced through the radioactive decay of potassium-40 in rocks on Earth.
When radioactive isotopes break down into other elements the process is called?
radioactive decay
What emits rays?
Many objects in the universe emit rays, such as stars emitting light rays, radioactive elements emitting gamma rays, and X-ray machines emitting X-rays. Rays can also be emitted from phenomena like solar flares, cosmic rays, and radioactive decay.
Is dueterium radioactive?
No, deuterium is not radioactive.
Is graphite radioactive?
No, graphite is not radioactive.
Is water radioactive?
No, water is not radioactive.
