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
Product was as advertised and arrived pretty quickly too! The person loved their gift!
The "Pink Flamingo" colour with white text on a pink background is the best selection for this fine phrase mug. May I suggest you also correct the misspelling of "delightfully" in the default option for a timeless gift.
As always, a great gift.
It looks great. I couldn't have been happier
It’s a mug I would never find in a souvenir shop. I’m a legend in my own home.
I am very please with the mug. Thank you!

Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome
I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
the urge to buy it and write cum on it
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.
It’s a great way to store my pencils.
I used this instead of condoms It didn’t work and now my nephew is my son
Ordering was very easy and the delivery to a different address then the billing address was done effortlessly with complete correct order. Was delivered before estimated date which was very exciting. Good job well done by all.
Funny stuff! I wish the mugs cost a bit less, I'd buy more. There's an almost unlimited supply of clever slang.
awesome. came just as ordered.
