The Rosette Nebula skull is a massive star-forming area in the constellation Monoceros, the Unicorn. The nebula is a huge cloud of gas and dust that resides near a big molecular cloud and is intimately linked to the open cluster NGC 2244, whose stars were created in the last five million years from the nebula’s materials.
Rosette Nebula is 5,219 light-years away from Earth and 65 light-years in radius. It is formed like a rose or a flower, which is why it gets its name “Rosset.” This rose’s petals are a star nursery, where new stars are born.
The most interesting fact is that this nebula has been called the “Skull” because it gives the shape of a human skull in some orientations. As a reason, there are a lot of people attempting to see and capture the skull shape.
To see the Rosette Nebula visually, orient your telescope to the right part of the constellation Monoceros and left of Orion the hunter. It is best to view it under a dark, moonless sky.
