The Hubble image reveals a huge ultra-violet atmosphere with a mysterious hot spot on the stellar surface. Most supergiants end their lives catastrophically as a supernova . This happens when the fuel in the core runs out, and so cannot withstand the pressure of the stellar material above.
Gravity makes it collapse in on itself - causing the explosion.
What remains is frequently a neutron star , or often a Black Hole . The H.S.T. continues to break down the limits of our knowledge about the Universe.
