you could con a mickle about a Galax urceolata base solely on its semblance . How honest-to-god it is , whether it ’s still bring out star , the age of the star themselves — these are all question that a beetleweed ’s color can help answer .
But our place proportional to the Milky Way ( i.e. the fact that we ’re in reality inside it ) signify our perception of its true color is skewed . Now at last , stargazer have determined the colour of our galaxy as it would come along from an outsider ’s perspective . So just how milky looking is the Milky way of life really ?
Well , evidently , it ’s pretty darn milky — that is to say : it ’s white . But not just any white . According to Jeffrey Newman and Tim Licquia — who deduced the Milky Way ’s hue by averaging data point from 1,000 similar galaxies — the galaxy resemble the colour of a fresh leaping C in the hours shortly after dawn , or “ roughly midway between the lighting from old - flair incandescent light bulbs and the stock spectrum of albumen on a television . ”
The answer may go obvious ( it is , after all , called the Milky Way ) , but it actually is n’t , for at least two reasons .
The first is that our position within the galaxy is such that swarm of gas and rubble unsung all but the closest realm of our extragalactic nebula from prospect . For years , this has prevented uranologist from baffle an musical theme of what the milklike Way looks like as a whole . “ The problem , ” explains Newman , “ is similar to square up the overall color of the Earth , when you ’re only able to tell what Pennsylvania look like . ”
The 2nd is that the Milky Way ’s colour is actually best described as a intermixture of ruby-red chromaticity from the coltsfoot ’s core , and dispirited from its spiral arms . mostly speaking , cherry corresponds to regions of a wandflower where star formation is rare , while blue indicate where stars are still being born .
“ It appears our Milky Way is on the road between those two stages , ” Newman told the BBC . “ base on the colour we find , the rate of formation of star has been declining over time . ”
“ The Milky manner is in a very interesting evolutionary commonwealth right now . ”
Newman and Licquia announce their results yesterday at the 219th American Astronomical Society meeting . you’re able to say more about their findings over atBBCandDiscovery News .
