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.
A nebula is a cloud of gas or dust in space that may reflect light emanating from nearby stars. 'Nebulae' is just the plural form of 'nebula.' A nebula is the location of where something called the interstellar medium (ISM) is densest.n emission nebula is a glowing cloud of ionized gas that is excited by ultraviolet radiation absorbed from hot nearby stars. Such a star must be hotter than 25,000 K to emit enough UV radiation to ionize the gas. When a gas is ionized, it's excited and produces an emission spectrum with a distinct pink color.
