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.
CO and H. Since the regions are dense, they are opaque to visible light and are known as dark nebula. Since they don't shine by optical light, we must use IR and radio telescopes to investigate them. Star formation begins when the denser parts of the cloud core collapse under their own weight/gravity. These cores typically have masses around 10 4 solar masses in the form of gas and dust.
