The Bubble Nebula NGC7635

Even from the heart of Brussels, the universe's wonders shine through! This breathtaking view of the Bubble Nebula (NGC 7635) captures a cosmic spectacle sculpted by stellar winds.

Located about 8,000 light-years away in the constellation Cassiopeia, this nebula is a testament to the raw power of a massive young star. The intense radiation and stellar winds from this star have blown a giant bubble in the surrounding interstellar gas, hence its fitting name.

The vivid colors represent different elements: the bubble's edge glows blue due to oxygen, while the surrounding gas is illuminated in red by hydrogen. It's a captivating reminder of the dynamic forces at play in our universe.
