The Core of M87 (at the center of Virgo)

The Core of M87 (at the center of Virgo). Radio Jets. Giant Radio Lobes. If the jets last long enough, they can blast out of the galaxy for millions of light years: the largest single coherent structures in the universe. Seyfert Galaxies. Some galaxies have unusually bright nuclei….

Cepheids are the key link

Cepheids are the key link

Cepheids are the key link. One primary justification for the Hubble Space Telescope was to . resolve Cepheids in galaxies far enough away to measure the Hubble flow properly, and thus obtain the age of the Universe. Along with other methods, this gives about 14 billion years .
