Question

sun is burning but their is no oxygen in space how it is possible

Answer 1

due to the presence of hydrogen

Answer 2

Since fire needs oxygen, and there is almost no oxygen in space, then how can the sun burn constantly? Well, the sun isn’t “burning” in the same sense that a fire burns on earth. The sun produces energy the same way that a hydrogen bomb produces energy.

In this process, hydrogen is changed into helium, but some hydrogen is instead converted into energy. So the sun continues to “burn” and produce light and heat without oxygen.
