|Blue Agave Supernova|

Pastel on Sennelier LaCarte
When naming this painting, I didn't even consciously realize tomorrow was going to be "space" day. But, as always, my subconscious knew. This is another larger painting for me - two to four times the 'usual' size. Therefore, it needed to be a big name. While I'd like to say a star was born, the truth is that a Super Nova is the end - or is it the beginning of something else. This star went Supernova - a blue agave star.
Excerpts from "What is a Supernova?"
What Causes a Supernova?
A supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.
The first type of supernova happens in binary star systems. Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.
The second type of supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.
Why Do Scientists Study Supernovas?
A supernova burns for only a short period of time, but it can tell scientists a lot about the universe.
One kind of supernova has shown scientists that we live in an expanding universe, one that is growing at an ever increasing rate.
Scientists also have determined that supernovas play a key role in distributing elements throughout the universe. When the star explodes, it shoots elements and debris into space. Many of the elements we find here on Earth are made in the core of stars. These elements travel on to form new stars, planets and everything else in the universe.
