M97 – The Owl Nebula
M97 is also known as the Owl Nebula, located about 2,000 light years away just under the bottom of the big dipper. Only about 8,000 years old, the nebula was formed when a star twice the size of the Sun (in the centre of the nebula) reached it’s last phase of life and began ejecting large quantities of Oxygen (green) and Hydrogen (red) gas.
