Astronomy (from Greek: ἀστρονομία) is a natural science that studies celestial objects and phenomena.It applies mathematics, physics, and chemistry in an effort to explain the origin of those objects and phenomena and their evolution.Objects of interest include planets, moons, stars, nebulae, galaxies, and comets; the phenomena also includes supernova explosions, gamma ray bursts.

This ranges from the simple things you may be familiar with, like an electron absorbing a photon (or what you call "why sunlight feels warm"), to the rare decays of bound states of unstable.
