The space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.
As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer of German origin, William Herschel.
Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova. …. I don’t know about you but I can't wait to see this
