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.
Massive stars form in the same way as low mass stars--they just form more quickly because there is more mass to speed-up the process. Whereas the Sun took about 50 million years to contract from a cold gas cloud to a main sequence star, a star with 15 solar masses collapses to the main sequence in 60,000 years.
