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.
Other types of nebulae include emission nebulae, which are clouds of ionized gas emitting light of various colors; dark nebulae, which are clouds of gas so dense that background light is blocked; and protoplanetary nebulae, which occur when a star starts to shed its outer layers before becoming a planetary nebula.aturn Nebula NGC 7009: Located in the constellation Aquarius, the Saturn Nebula, or NGC 7009, has a bright central star surrounded by a football shaped array of gas and dust. Stingray Nebula (Hen-1357): The youngest known planetary nebula, Hen-1357 is as large as 130 solar systems.
