NASA/IPAC Extragalactic Database of Galaxy Distances

Ian HeadshotI seek our universe’s exact age, size, shape, and makeup. Big questions, yes, but doable thanks to big data now in on our biggest measurements. Distances to galaxies beyond the Milky Way (as shown above) that are redshift-independent and published since 1980 are tabulated by the NASA / IPAC Extragalactic Database of Galaxy Distances, which I co-lead in collaboration with Dr. Barry Madore.
