For leg 3 of Celebration of Early Astronomy 8, we are moving from the Seagull Nebula down below to the Jellyfish Nebula, and passing through the NGC 2244 cluster as well as the Rosette Nebula along the way.

- POI:NGC 2244 Cluster Start
- NGC 2244, also known as Caldwell 50 is a young cluster in the Rosette Nebula. HD 46223 and HD 46150 are the two brightest members of the cluster. While the former is not in the game, the latter, HD 46150 curiously is in-game but 1,383.34 Ly away from the cluster (as measured as distance from HD 258691).

- POI: Rosette Nebula
- The Rosette Nebula, also known as Caldwell 49 is an ionized hydrogen star forming nebula (known as an H II region) in the Monoceros region of the sky as seen from Earth. NGC 2244 is also related to this nebula, having been formed rom the nebula’s matter. There are over 2,500 yound stars in the star forming region of this nebula. Rosette Nebula is also the official astronomical object of the U.S. State of Oklahoma as designated by their legislature in 2019.
In real life the nebula look similar to a human skull and is often also called the Skull Nebula. (Image: https://en.wikipedia.org/wiki/Rosette_Nebula#/media/File:SHO_Final_with_copyright.jpg)
This particular system also is home to the asteroid base New Beginning for your use for any station based needs. - SIMBAD Link

- Map Reference: HD 45829
- HD 45829 is a red supergiant that was studied in a 1989 paper of red supergiants that were either far from the galactic plane or moving at unusually fast velocities. HD 45829 being studied as one of the latter. It showed blueshifted Hydrogen-alpha emission wings indicating that it was likely outflowing mass rapidly.

- POI: Jellyfish Nebula
- Jellyfish Nebula, also known as IC 443 is a supernova remnant in the Gemini constellation of the night sky as seen from Earth. It appears in the sky near Eta Geminorum, officially known as Propus, which can also be found in the bubble in-game.
Jellyfish Nebula is the remnant of a supernova that occurred 30,000 to 35,000 years ago that likely created the neutron star CXOU J061705.3+222127 which is believed to be the collapsed core of the original star.
Jellyfish Nebula is heavily studied for how supernovae remnants interact with pre-existing molecular clouds as part of the complex making up this nebula is another remnant shell from a supernova estimated to be from around 100,000 years ago known as G189.6+3.3.
Unlike some other supernova remnants like Crab Nebula though (which we will see on a later leg), Jellyfish Nebula is not dominated by the pulsar’s wind. - SIMBAD Link for CXOU J061705.3+222127
