Hubble’s LawBelow is a table of galaxies, their distances, and their velocities.GalaxyDistance(Mpc)H-Alpha(angstroms)Velocity(Mm/s)Age(billion yrs)NGC 135724.7266082.1911.29NGC 183230.996606.72.0215.34NGC 277517.896591.21.4612.25NGC 29036.966574.90.4515.47NGC 336811.896603.60.8813.51NGC 351640.006612.92.5315.81NGC 36279.576578.80.7213.29The table is not yet complete. You will collect the missing data and graph Hubble’s law tomeasure the age of the universe.1.Visit theHubble’s Law lab pageand use the clickable spectra to measure the observedlocation of the H-alpha emission line for each of the galaxies included in the table above.Enter your measured values in the table. (For help on using the clickable spectra, watchthe videoMeasuring the Speed of a Galaxy.)2.Use the blank graph below to chart the velocity of each galaxy versus its distance.3.How does the shape of your graph compare with the results that Hubble found?
