Constellation: Cassiopeia Type of object: Emitting nebulae Distance: 10,000 light-years Magnitude: 10.0 Discovered in : 1787 Fun Facts ! The Bubble Nebula is a shell of gas, about 7 light-years in diameter. To the left of the bubble's center is a large, bright star. It is thousands of times brighter than our sun and 45 times more massive. The stellar winds and radiation emitted by this star expel gas and other dense material, creating the shape of the bubble. The star still has 10 to 20 million years to live, before probably exploding into a supernova.
