What do you mean by the term fusion reaction?

This is a nuclear reaction in which the two nuclei join to form larger (with nearly combined mass) nuclei. In this reaction lots of energy is released.
Sun and stars discharge energy in this fashion.
Describe in brief the concept of nuclear reaction?
Roche limit: The position about a massive body where the tidal forces due to the gravity of the primary equivalent or exceed the surface gravity of a specified satellite. Within the Roche limit, such a satellite will be interrupted by tides.
Drake equation (F. Drake; 1961): The method of estimating the number of intelligent, scientific species (that is, able to communicate with other species) in subsistence in our space. N
