The Universe Nearby

This helps to get things in perspective.

The Universe Nearby
Credit & Copyright: 2MASS, T. H. Jarrett, J. Carpenter, & R. Hurt Explanation: What does the universe nearby look like? This plot shows over one and a half million of the brightest stars and galaxies in the nearby universe detected by the Two Micron All Sky Survey (2MASS) in infrared light. The resulting image is an incredible tapestry of stars and galaxies that provides limits on how the universe formed and evolved. Across the center are stars that lie in the plane of our own Milky Way Galaxy. Away from the Galactic plane, vast majority of the dots are galaxies, color coded to indicate distance, with blue dots representing the nearest galaxies in the 2Mass survey, and red dots indicating the most distant survey galaxies that lie at a redshift near 0.1. Named structures are annotated. Many galaxies are gravitationally bound together to form clusters, which themselves are loosely bound into superclusters, which in turn are sometimes seen to align over even larger scale structures.

Thanks for the interesting stuff you post.

The voids and filaments in the large scale structure of the Universe has been depicted many times before, however this map can be compared with the galaxy chains that appears on all sky maps such as those in the Cambridge Sky Atlas. The hypergalactic plane, for instance, is clearly visible in that map.
