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.
Perhaps the most famous image from the Hubble Space Telescope (HST) is that of the Crab Nebula. A nebula is a mixture of hot gas, dust and simple elements like hydrogen and helium. The Crab Nebula is approximately 6,500 light-years from Earth in the constellation Taurus. The nebula itself is an astonishing 10 light-years in diameter. To put that into perspective, if the Sun were the size of a basketball, the Crab Nebula would be the size of planet Earth.
