WebIn 1924 Edwin Hubble detected Cepheids in the Andromeda nebula, M31 and the Triangulum nebula M33. Using these he determined that their distances were 900,000 and 850,000 light years respectively. He thus established conclusively that these "spiral nebulae" were in fact other galaxies and not part of our Milky Way. WebMay 25, 1999: The Hubble Space Telescope Key Project Team today announced that it has completed efforts to measure precise distances to far- flung galaxies, an essential ingredient needed to determine the age, size and fate of the universe. Right: A NASA Hubble Space Telescope (HST) view of the magnificent spiral galaxy NGC 4603, the …

WebHow is the energy that powers radio galaxies, quasars, and other active galactic nuclei thought to be produced? By gravity, which converts the potential energy of matter falling toward a central black hole into kinetic energy, which is then converted to thermal energy by collisions among the particles of matter. WebHubble estimated that the true occurrence rate of novae in M31 must be about 30 per year, a figure that was later confirmed by the American astronomer Halton C. Arp in a … gpw architects
