2MASS Tuesday
http://www.dearastronomer.com/
This week is crazy busy for me, but having worked with the 2MASS data, this APOD image hits close to home and I had to write up a quick post. Even after eight years, researchers are still doing great work and making new discoveries with the data. I’d love a chance to work with the 2MASS data again or possibly improve on my previous work.

This plot shows nearly 50,000 galaxies in the nearby universe detected by the Two Micron All Sky Survey (2MASS) in infrared light. Bluer dots represent the nearer galaxies in the 2MASS survey, while redder dots indicating the more distant survey galaxies that lie at a redshift near 0.1. Named structures are annotated around the edges. 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.
