Diagram Milky Way - the milky way is the galaxy that contains our solar system the name describes the galaxy s appearance from earth a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye the term milky way is a translation of the latin via lactea from the greek galax 237 as k 253 klos milky circle milky way galaxy milky way galaxy sometimes simply called the galaxy large spiral system of about several hundred billion stars one of which is the sun it takes its name from the milky way the irregular luminous band of stars and gas clouds that stretches across the sky as seen from earth the hertzsprung russell diagram abbreviated as h r diagram hr diagram or hrd is a scatter plot of stars showing the relationship between the stars absolute magnitudes or luminosities versus their stellar classifications or effective temperatures more simply it plots.
each star on a graph plotting the star s brightness against its temperature color our milkyway galaxy this image of our galaxy the milky way was taken with nasa s cosmic background explorer s cobe diffuse infrared background experiment dirbe the european space agency released a new map of nearly 1 7 billion stars from the gaia spacecraft giving the best ever view of the milky way and neighboring galaxies in color the milky way galaxy might be twice as wide as astronomers thought a new study measured stars at the very edges of our galaxy and they are a lot farther away than predicted the hr diagram for a specific case figure 3 hr diagram for globular cluster m5 in figure 3 above we see an hr plot of the stars in globular cluster m5 i shamelessly confess that i took this diagram from that page the x axis plots b v which is the color index and b v means b minus v where b and v are the.
relative brightness of the b and v colors in the system of magnitudes the hertzsprung russell diagram is a graph of many stars it shows the relation between stars luminosity that is how bright they are and their temperature how hot they are these diagrams are not pictures or maps of the locations of the stars rather hertzsprung russell diagrams plot each star on a graph measuring the star s brightness versus its temperature a look up at the night sky reveals a treasury of wonders even to the naked eye the moon stars pla s the milky way and even a few star clusters and nebulae illuminate the heavens little biologists will use this respiratory system diagram to identify the most important parts of the human respiratory system and their functions
