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.
The Urban Dictionary Mug
This mug made me horny.
looks perfect!!! we loved it
I ordered 4 of your mugs -- and have received 3; hopefully, the 4th is on its way! So far, I've received "fame," "620," and "$" ... only needing "hulo." ...It might be a matter of me being patient, that the 4th mug is on its way. However, the 3 received SO far are all EXCEPTIONAL, in every way!!! Mark Moilanen
I love this mug with a burning passion in my heart, I have purchased 7 of these mugs and intend to continue. This mug has changed my life for the better
it's the best mug of the world !!!!!
wow! this mug is so thoughtful to giving to my wife!
The description tells nothing but facts. 5 stars instant
Your description is right on, except in 1989 I named my daughter Kallen Mikel (www.kallenmikel.com/original-art). I thought I made up the name, but apparently, it originated as a boy's name in Greek and Hebrew. I first found this out in 2001 when I was traveling to Finland. In the 'tube food' section in a big Finnish supermarket there it was, a royal blue tube of salmon paste with a blonde-haired boy named Kallen! So now I have discovered that there are many Kallen's of both sexes. I want to buy her a cup, but it has 'him' on it. Is there any way you can make that a unisex description for both sexes? Just askin'. Being a Barbara (Barbs) myself ... a 'cake eater' from Edina, MN I had to ask ... haha ;-)
Thank you for the mug. It arrived fast and exceeded my expectations.
I loved my mug and it came in a timely fashion.
