Australia's latitude is south and its longitude is east. This is because Australia is located below the equator in the southern hemisphere and to the east of the Prime Meridia â¦ n in the eastern hemisphere.
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
Our Sun was born within a dense nebula 4.6 billion years ago. Gas and dust contracted into a giant cloud, then floated in one of the spiral arms of the Milky Way. As our Sun aged, it grew larger, brighter, and hotter â eventually causing nuclear fusion in the protons at the centers of its atoms.
