Hubble telescope captures giant star blowing bubbles into space

To mark the Hubble’s 26th anniversary in space, scientists took a picture of the Bubble Nebula, which is basically a giant star blowing bubbles. For a more scientific explanation, I turn to Science News:

(It is) a seven-light-year-wide pocket of gas being blown away by a blazing massive star about 7,100 light-years away in the constellation Cassiopeia. The star responsible for the bubble… is so hot and bright that it launches its own gas into space at more than 6 million kilometers per hour.
