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.
The Horsehead Nebula, one of the most famous dark nebulae, is located in the constellation Orion. 1  Emission nebulae are huge bright gas clouds with irregular shapes and dimensions that span many light years across. 2  Reflection nebulae are usually faint and shine with the reflected light of the stars within them. They are the remains from the former dense cloud of an emission nebula. Once stars are born inside an emissions nebula, they consume large amounts of the nebula's dust and gas, and the remains continue to shine with a faint reflected bluish light. An example is Pleiades in the Taurus constellation.
