The M95 galaxy, the Sunflower Galaxy (also known as NGC 5055), is located in the constellation Canes Venatici. It is a spiral galaxy 29 million light years away. The galaxy is active (weakly), which means it is producing stars in the red regions. Those regions are hydrogen emissions (hydrogen-alpha).

Thor’s Helmet (NGC 2359 or SH2-208) is an emission nebula in Canis Major located 12 thousand light years away. At the center of the round bubble is a Wolf-Rayet star, that is thought to be at the early stages of a supernova. This is similar to what is happening in the Bubble Nebula. The Wolf-Rayet type star is what is making this nebula shine.
