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.
At the center of the nebula lies the Crab Pulsar, a neutron star 28â30 kilometres (17â19 mi) across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves.n 1928, Edwin Hubble proposed associating the cloud to the star of 1054, an idea which remained controversial until the nature of supernovae was understood, and it was Nicholas Mayall who indicated that the star of 1054 was undoubtedly the supernova whose explosion produced the Crab Nebula.
