Milky Way Galaxies Diagram of the nearby local group of galaxies including the milky way, the magellanic clouds, andromeda, dwarf galaxies, globular cluster and stellar streams. the list aims to reflect current knowledge: not all galaxies within the 3.8 mpc radius have been discovered. Supernova type ia: extends calibration to faraway galaxies, linking the local and cosmological scales. by using these nearby galaxies, astronomers can refine the hubble constant (h₀) with great precision.
Milky Way Galaxies But let’s zoom back and take a look at the galaxies that are closer to us. below you will find a list of nearby galaxies ordered by distance starting from the ones closer to our own galaxy, the milky way. What is a galaxy? the short answer: a galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. we live on a planet called earth that is part of our solar system. but where is our solar system? it’s a small part of the milky way galaxy. But a peek over the celestial fence beyond the milky way’s tenuous halo yields a rich view of the nearby universe and galaxy evolution in progress. the approximately 85 gravitationally. This is a list of known galaxies within 3.8 megaparsecs (12.4 million light years) of the solar system, in ascending order of heliocentric distance, or the distance to the sun.

This is a list of known galaxies within 3.8 megaparsecs (12.4 million light years) of the solar system, in ascending order of heliocentric distance, or the distance to the sun. Type ia supernovae and entire spiral galaxies are brighter than cepheid variables, so they extend our capability to measure distances out to billions of parsecs. In the late 1990's, there were two independent teams of astronomers trying to find and record type ia supernovae in distant galaxies as part of a larger study trying to understand the fundamental nature of the cosmos. Without distances, the night sky is a flat tapestry; with distances, it becomes a three dimensional, evolving cosmos. astronomers assemble answers using a carefully interlocked framework known as the cosmic distance ladder. The best standard candle for determining the distance to the nearby galaxies is the cepheid variable star. these are bright and reasonably common, with strong identifying signatures, so their observation in other galaxies is not too difficult.
