Bubble Nebula

Bubble Nebula Astronomy Aviation & Space Exploration STEM Visual Arts

The Bubble Nebula - NGC 7635 - is known as a “space bubble.”  What created this space bubble?

To answer that question, let’s check-in with NASA:

What created this huge space bubble?  A massive star that is not only bright and blue, but also emitting a fast stellar wind of ionized gas.

The Bubble Nebula is actually the smallest of three bubbles surrounding massive star BD+602522, and part of gigantic bubble network S162 created with the help of other massive stars.

As fast moving gas expands off BD+602522, it pushes surrounding sparse gas into a shell. The energetic starlight then ionizes the shell, causing it to glow.

The above picture taken with the Hubble Space Telescope and released last week [that is, during early January of 2000] shows many details of the Bubble Nebula never seen before and many still not understood.

The nebula, also known as NGC 7635, is about six light-years across and visible with a small telescope towards the constellation of Cassiopeia.
