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.
What is the biggest star we know? Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy. In 1995, it was suggested that the Pistol Star was so massive it was throwing off the mass that actually created the Pistol Nebula. Observations from the Hubble Space Telescope in 1997 confirmed the relationship between the star and the nebula. Astronomers are currently unsure how a star this massive could have formed or how it will act in the future. The Pistol Star appears as the bright white dot in the center of the image shown above. The Hubble Space Telescope's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) was needed to take the picture, because the star is hidden at the galactic center, behind a great deal of obscuring dust.
