Dwarf Galaxies in the Coma Cluster
Thousands of dwarf galaxies were discovered in the Coma Galaxy Cluster using infrared images from the Spitzer Space Telescope. Visible light images from the Sloan Sky Survey are combined with the infrared data to create this composite. The cluster spans about 20 million light-years, holding over a thousand visible galaxies and many more unseen dwarfs.

In tropical astrology, 31 MAY 2007 falls under Gemini (♊). The sign's window runs from 05-21 through 06-20. Gemini is named for the twin stars Castor and Pollux, both bright enough to spot without a telescope. The Sun was crossing this region of the sky on 31 MAY 2007.
