The 2MASS Redshift Survey


“The 2MASS Redshift Survey (details here) took 10 years to complete, and it has now yielded the finest 3D map of the universe ever made, cataloguing more than 43,000 galaxies within 380 million light-years from Earth. The new map was presented last week at the 218th meeting of the American Astronomical Society. You can view the map in a much bigger format here and, as one user suggests, you may want to “right click and save as desktop background.”

NASA Images


“NASA Images was created through a partnership between NASA and the Internet Archive, a non-profit digital library based in San Francisco, to bring public access to NASA’s image, video, and audio collections in a single, searchable resource.

The site contains everything from classic photos to educational programming and HD video, and is growing all the time as we continue to gain both new and archived media from all of NASA’s centers.

Through the development of we hope to promote education and facilitate scholarship in the math and sciences at all levels, and to build general interest and excitement around space exploration, aeronautics, and astronomy.
