Hydrogen is the element that makes up over 90% of the atoms in our galaxy. It is the most abundant element in the universe and plays a crucial role in the formation of stars and galaxies. In addition to hydrogen, helium is the second most abundant element, but its presence is significantly less than that of hydrogen. Together, these elements are fundamental to the structure and evolution of the cosmos.
