Lobster Claw Nebula and the Bubble Nebula

The Lobster Claw Nebula (SH2-157), and the Bubble Nebula (NGC 7635). The Bubble Nebula is 7,100 light years from Earth, and the Lobster Claw Nebula is 11,000 light years away. You can find this pair in the constellation Cassiopeia. A 4 million-year-old star forms the Bubble Nebula and is 45 times more massive than our sun. The temperature is so extreme that gas is emitted from the star at 4 million miles an hour, also known as stellar wind. This event causes the "bubble" as seen in the bottom left.
