How Is It Possible To Tell What Stars Are Made Of When They Are So Very Far Away? The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy. Today, this process uses instruments with a grating that spreads out the light from an object by wavelength. This
How Stars Are Formed Step By Step? STAGE 1: AN INTERSTELLAR CLOUD. STAGE 2: A COLLAPSING CLOUD FRAGMENT. STAGE 3: FRAGMENTATION CEASES. STAGE 4: A PROTOSTAR. STAGE 5: PROTOSTELLAR EVOLUTION. STAGE 6: A NEWBORN STAR. STAGE 7: THE MAIN SEQUENCE AT LAST. How are stars made step by step? Star Formation Shapes the Appearance of
How Heavy Elements Form In Massive Stars? After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and
How Does Distance Affect The Time Light From A Star Takes To Reach Earth? The apparent brightness of a star is proportional to 1 divided by its distance squared. That is, if you took a star and moved it twice as far away, it would appear 1/4 as bright; if you moved it four times
Where Can I See The Gemini Constellation? Gemini is fairly easy to spot in the sky, even for amateur stargazers. It is located northeast of the constellation Orion and between the Taurus and Cancer constellations. Best viewing is during February. By April and May, the constellation can be seen soon after sunset in the west.
What Will Decide The Amount Of Time A Star Spends In The Main Sequence Phase? The length of time a star spends in the main sequence phase depends on its mass. “Constructing a plot, called the HR diagram, of the stars in the cluster, scientists can determine the mass of the stars that are just
Which Element Stops Fusion In A High Mass Star? Higher mass stars will switch from helium to carbon burning and extend their lifetimes. Even higher mass stars will burn neon after carbon is used up. However, once iron is reached, fusion is halted since iron is so tightly bound that no energy can be extracted
Where Would You Expect To See The North Star If You Were Standing At The North Pole Quizlet? Where would you have to look to see your zenith? If you were standing at the Earth’s north pole, the north celestial pole would lie at the zenith, the imaginary point directly over your head. The star
Where Do Stars Get Their Light? Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives
Which Color Star Is The Coldest? You can tell a lot about a star by its color. You can tell the temperature of the star. Red stars are the coolest. Yellow stars are hotter than red stars. Which color star is hottest? The hottest stars tend to appear blue or blue-white, whereas the coolest stars
