Hubble used the light curves of the Cepheid variables to measure their distances from Earth and found that they were much farther away than the known limits of the Milky Way. Therefore, these spiral nebulae were indeed other galaxies outside our own. There are still many mysteries surrounding ...
Shapely was involved in a great debate about the nature of spiral nebulae (faint patches of light visible in the night sky). He believed that they were "island universes," or galaxies outside the Milky Way. Another astronomer, Heber Curtis, believed that spiral nebulae were part of the Milk...
I think I become more susceptible to the wow factor of some targets with experience. I have seen M42 hundreds of times though an eyepiece. When seeing is exceptionally good the stars become tighter and nebulae seem less defuse. Last night was one of those nights when I looked at the trapez...
What is the difference between nebulae and planetary nebulae? What are galaxies made of? What does a spiral galaxy look like? How big is the Oort cloud compared to Earth? What does the redshift of galaxies indicate? Are all Oort cloud objects comets? How many galaxies are in the observable...
a C11. Now I own the Edge versions of 8 inch, 11 inch, and 14 inch scopes. I am used to seeing dust lanes in galaxies, thousands of individual stars in globular clusters, good color and separation from double stars, and even some vivid color from some nebulae, especially with my C14...
