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.
Nebulae form in three ways: 1. Through gravitational collapse, 2. Through supernova explosion of a massive star, and 3. Through shedding off the outer layers of a less massive star. Through gravitational collapse: Diffuse nebulae are formed from the explosions of older stars, and the leftover hydrogen and helium from the Big Bang.
