C11 / NGC 7635 The Bubble Nebula - telescope processed image with LP filter. It is created by the fierce stellar wind from a massive O-type star (SAO 20575), which is 45 times more massive than our Sun.
C11 / NGC 7635 The Bubble Nebula - telescope processed image without LP filter. The star isn't in the middle; it’s off-center because the bubble expands into gas of varying densities in the interstellar medium.
C11 / NGC 7635 The Bubble Nebula - unprocessed image with LP filter. The bubble is roughly 7 light-years across, meaning it’s about 40 trillion miles wide—large enough to swallow many solar systems.
C11 / NGC 7635 The Bubble Nebula - unprocessed image without LP filter. The gas shell is expanding at an incredible rate of approximately 4 million miles per hour (roughly 1,800 kilometers per second).
