NGC 7635 BUBBLE NEBULA

The Bubble Nebula, NGC 7635, is 7 light-years across – about one-and-a-half times the distance from our sun to its nearest stellar neighbor, Alpha Centauri – and resides 7,100 light-years from Earth in the constellation Cassiopeia. Sharpless 157, also known as the Lobster Claw Nebula (lower left), is a bright emission nebula in the constellation Cassiopeia. It lies just south of the Bubble Nebula.
