Hydrogen and Helium. Mainly Hydrogen which it uses to release energy.
How does the Sun generate light
The Sun generates light and heat energy through a process called nuclear fusion.
What causes the seasons of Earth.

How do solar eclipses occur and what are they?
They happen when the Earth Moon and Sun are perfectly aligned so that the Moon completely blocks the Suns light from reaching Earth.

A partial solar eclipse occurs when the Moon does not completely cover the Sun. A total eclipse is when the moon completely covers the Sun.
What are the phases of the Moon.
Who invented the first telescope?
Galileo
What is the difference between a refracting and a reflecting telescope
Refractor telescopes utilize specialized lenses that make them a favorite for deep space objects like galaxies and nebulae. In contrast, reflector telescopes are more popular with larger and brighter objects like the Moon and planets because they use mirrors that provide more sensitivity to all wavelengths.
What are the uses of telescopes in Astrophysics
A telescope is a tool that astronomers use to see faraway objects. It helps focus the light reflected from the planets and stars, into ours eyes.
What are the advantages and disadvantages of refracting and reflecting telescopes.
Refracting telescopes use a lens to capture light and are more expensive. They dont need cleaning.
Reflecting telescopes need regular cleaning. They are generally cheaper. No need to worry about a fragile lens at the edges.
