There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

This is a rotation around a dwarf galaxy with a total mass of 10^9 solar masses (about 1000 times smaller than our Milky Way) at redshift 7 when the universe was only 800 million years old. The galaxy is viewed at 25,000 light years away.
The brightness of the gas indicates its density, and blue and red correspond to warm and cool gas temperatures, respectively. The stars are colored by their ages with older and newer stars shown in yellow and blue/white.
