Visibility IV / V
The hydrogen rose Rosette flies midnight into the winter southern sky stage. This huge emission nebula can be found in the unicorn constellation. The distance of the fog is about 5,000 light-years. In the middle of it is an open array of hot stars that have blown a bubble into the surrounding hydrogen vapor. The cloud itself is 130 light-years in diameter. It contains a wealth of interesting structures and star-bearing regions.
