What Star Has A Temperature Of 20000 K? O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. These stars have few absorption lines, generally due to helium. These stars burn out in a few million years. B stars What star has a temperature of 2500 K? The sun has
Do Elliptical Galaxies Have O And B Stars? Ellipticals contain neither interstellar dust nor bright stars of spectral types O and B. Many, however, contain evidence of the presence of low-density gas in their nuclear regions. How are the stars distributed in an elliptical galaxy? Unlike flat spiral galaxies with organization and structure, elliptical galaxies
Does High Mass Stars Live Longer Than Low Mass Stars? The incredibly rapid fusion rates mean that high-mass stars cannot live very long. – A 25 solar mass star only spends a few million years on the main-sequence (Remember the sun spends 10 billion years on the main sequence). When the core hydrogen is exhausted
Why Can’t I See Stars At Night? What has happened to the stars? Of course they’re still there, but we can’t see them because of light pollution: the excessive and misdirected anthropogenic and artificial light that has invaded our night skies. Stars have helped shaped human culture for thousands of years. How many stars we

What Is The Lifespan Of Most Stars? A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long. What is the lifetime of a star? This is indeed correct; the most masive stars burn out in
Are Stars The Same Color But Different Temperatures? Are stars the same color but different temperatures? As a star’s temperature increases, as a result of there being more gas in the star – and hence more fuel to burn – it becomes hotter. Its colour changes from orange, through yellow, to white. The hottest stars
