Hundreds of thousands of volunteers have helped to overturn almost a century of galaxy classification, in a new study using data from the longstanding Galaxy Zoo project. The new investigation ...

Hubble also devised a classification system for galaxies, grouping them according to their content, distance, shape, size and brightness.

Edwin Hubble joined the Mount Wilson Observatory team in California in 1919, just two years after the observatory’s Hooker Telescope, which was the largest telescope in the world at that time ...

NGC 3430's distinct shape may even have inspired astronomer Edwin Hubble to use it to define his classification of galaxies.

The same Cepheid stars, subjected to the same analytical techniques, enabled Edwin Hubble to appreciate the enormous distances to the spiral nebulae. Hubble used Cepheids in 1924 to show that the ...

Recent observations of vast numbers of galaxies may pose problems for the galaxy classification scheme proposed by Edwin Hubble. The tidy system of classifying galaxies on a linear sequence ...

How Edwin Hubble won the Great Debate A century ago, a brash astronomer leaked a discovery that opened our view to the cosmic distance scale and the nature of galaxies.

Edwin Hubble’s work on galaxies is legendary. In 1923 the astronomer, working at Mount Wilson Observatory in California, proved that M31, the “spiral nebula” in Andromeda, was another galaxy ...
