Supernova
Violent explosion of a star. The star is destroyed, with a remnant forming a neutron star (pulsar) or black hole (collapsar) depending on the residual mass. There are generally two forms of supernova. One results at the end of the life of a star with at least about eight solar masses, which in a series of progressively shorter-lived and less efficient thermonuclear reactions generates ever heavier chemical elements in layers about the core. Effectively this is a star that lives fast and dies young. When each step in the process chokes up the core with nuclear "ash", contractions follow under gravity, driving up temperatures until they are sufficient to synthesise the next heavy element from this waste product. When the core fills with iron, the end point is reached; it takes more energy to fuse iron into anything heavier than the fusion reaction produces. At this point the star collapses, driving temperatures into perhaps twelve figures Kelvin and triggering an explosion that blows most of the star to smithereens. A second type occurs in close orbiting binary systems where one star A, being more massive, evolves more quickly to the red giant phase and develops a thin outer envelope and a core rich in carbon. Its companion B skims off the outer layer, grows in mass and itself evolves to the red giant stage. At this point the carbon-rich star A begins reclaiming the hydrogen; when the gas accreting onto it drives its mass over 1.4 solar masses a huge nuclear reaction ensues and A blows itself apart. Supernova explosions can briefly outshine the combined output of all the stars in at least a modest galaxy. They are also responsible for seeding the Universe with the heavy chemical elements of which the Earth and our very bodies are made.

Every web purchase should be this easy! Love it!
Great quality, although a high price for a mug! Printed really nicely and came out really well. $30 worth the laugh.
High quality finish

gave it to my mom, she was proud. (shes dead)
My maiden name was Puddy and I just loved this mug that defined what Puddy means! I bought one for my brother as well as one for me… And this is the first time in all of our 70 + years that we have heard Puddy defined! We both are super grateful!
The color of the block highlighting the subject word was labeled "Flamingo Pink", but on the mug, it's actually closer to lilac and the woman I bought this mug for loves the color pink. I do like the apparent permanence of the design on the mug, I'm just disappointed with the inaccuracy of the color.
One day when I was walking down the street a man gave me this mug and said that it will be the best thing that ever happened to me, when I got home I filled the mug with the most delicious coffee and I became a penis. this is the best mug in the world thank you kind stranger for giving me this.
