Travel to 8000 light years under the sea. We would almost be tempted to catch the cosmic bubbles escaping from the depths of space to hear them pop in this environment where silence prevails. The NGC7635 bubble reaches more than 35,000 degrees, we step back and let ourselves simply be entertained by the ballet of bubbles and stars offered by Cassiopeia.
