Cassiopeia-A

siblings

sharpest blade and serpent’s tooth
a honest lie and deceitful truth
noxian heros, sworn to serve,
from their goal they cannot swerve

warrior light and enchantress dark
a war, a child, a forbidden spark
knowledge gained cannot be lost
no victory comes without cost

gutter children, army-sworn
fight to raise a brother alone
forget the softness of his love
chase only the glory from above

sister sweet and brother brave
storybook heroes from birth to grave
betrayed for a higher cause
demacia demands victory without pause

adopted brothers, bound by fate
learn the cost of love too late
one in balance the other in shade
but family ties do not so easily fade

by blood bound, by oaths sworn
these siblings shall never walk alone
not in life and not in death
bound by bone, blood and breath

Hello,

There is power to a name, an underlying presence to being defined by a word that ironically enough is given to us at birth, a name we have no choice in stating unless one has rather progressive or forward thinking parents. But the matter remains: what, exactly, lies in a name?

Of course there are angelic and biblical names, these of which have been passed down in humans and I have seen in a vast amount of variations, more of the archangels than my particular name however. It was once common for name to denote status, therefore a stronger name like that of a prophet or an archangel had a higher chance of being given to a baby as opposed to one of a cherub or seraph. I have yet to meet another named Castiel, though I have met a handful of “Cassandra”s, “Cassie”s, and one “Cassiopeia” that I had come to see as close to my own as humans could ever get.

Of course, many have also been names passed down from family members to children. Sam and Dean’s names are prime examples of that. That has also been a trend that I have noticed over the course of many years. There was a time I did not understand suffixes that corresponded to such names. It is even partly amusing to think there could very well once day be a “Samuel Winchester Jr.” that, up until a few years ago, I would have seen as somehow inferior. Humans are not juniors in status to others. It took a fair amount of convincing before I finally understood the concept more as an idea of honor as opposed to physical appearance.

There are names meant to represent an entity or idea, a symbolism so deeply rooted in the mixture of letters of a name that it transcends literature readings. Faith, Justice, the woman named Chastity in which I had met at a brothel with Dean once. These names now carry physical beings within the world in the representations of humans that are called as such, and yet they are taken as entirely different constructs when the name becomes a word once more. Of course, when one adds the layer of multiple languages after that the possibilities and results only infinitely augments as well.

It is an interesting exercise, to think about the origins of a person’s name and how it came to pass. Some histories carry more length than others, but all carry unique stories that apply to solely that one individual, even if there is more than one person of the same name. One day, I suppose, I could meet another with a name like myself. I would very much like to hear what they would have to say.

Yours,

Castiel

Tattered Remnants of a Star

10,000 light-years away in the constellation of Cassiopeia, a massive star went supernova, collapsing under the weight of its own gravity and blowing its outer layers into space, causing its own explosive demise. Shattered fragments are all that remain of the star—a huge swirls of debris and stellar ejecta called Cassiopeia A. It contains gases of 10 million degrees Celsius, created when the supernova flung out materials that smashed into surrounding dust and gas at speeds of 16 million km/hour. Cas A is actually the strongest radio source in the sky beyond our solar system, and the images above show the remnants in both optical and X-ray wavelengths, capturing the complex, intricate structure of the debris, fascinating in its utter destruction. The false colours indicate chemical compositions: bright green filaments are rich in oxygen, red and purple are sulphur, and blue are hydrogen and nitrogen. The light of Cas A first reached Earth just 340 years ago, so it’s one of the youngest and freshest such remnants we know of in the Milky Way. Studying it will help us understand the evolution of the universe. But it still holds some mysteries—take a closer look at the last image, and note the small turquoise dot right in the centre. Astronomers believe this is a neutron star—an ultra-dense star created during the supernova. Years of observation have shown unexpected rapid cooling of the star, which is thought to be caused by superfluids in its dense core. Superfluids are extremely bizarre but super cool, and you can read more about them from NASA.

Superfluid in Neutron Star’s Core

One of the most famous astronomical objects in the night sky is the Cassiopeia A supernova remnant. This image of Cassiopeia A was taken with NASA’s Chandra X-ray Observatory and shows three different energy bands of X-ray light. The white dot in the center of the image is Cassiopeia A’s neutron star. A neutron star is fast spinning, ultradense stellar remnant that’s left over after a massive star explodes. In fact, it’s the densest known object that is directly observable. Because it’s compressed by its immense gravitational field, a single teaspoon of neutron star material would weigh about 10 million tons. The pressure inside the core is high enough that most of the electrons there are forced into a degenerate state; they penetrate the atomic nuclei and fuse with protons, producing neutrons and a tremendous amount of energy, which is mainly radiated in the form of neutrinos. The rapid cooling in Cas A’s neutron star – through neutrino emission, suggests that the neutrons in its core are in a rare form of matter known as a superfluid. Superfluids are very strange, they are friction-free, can flow upward, escape airtight containers, and also behave as if they are a single particle.

Super Nova Cassiopiea A

Cassiopeia A is a supernova remnant in the constellation Cassiopeia and the brightest extrasolar radio source in the sky at frequencies above 1 GHz. The supernova occurred approximately 11,000 light-years (3.4 kpc) away in the Milky Way. The expanding cloud of material left over from the supernova now appears approximately 10 light-years (3 pc) across from Earth’s perspective (within the Milky Way Galaxy). Despite its radio brilliance, however, it is extremely faint optically, and is only visible on long-exposure photographs.

It is believed that first light from the stellar explosion reached Earth approximately 300 years ago but there are no historical records of any sightings of the progenitor supernova, probably due to interstellar dust absorbing optical wavelength radiation before it reached Earth (although it is possible that it was recorded as a sixth magnitude star 3 Cassiopeiae by John Flamsteed on August 16, 1680). Possible explanations lean toward the idea that the source star was unusually massive and had previously ejected much of its outer layers. These outer layers would have cloaked the star and reabsorbed much of the light released as the inner star collapsed.

Kappa Cassiopeiae - A Runaway Variable Supergaint Star

Approximately 4000 away from earth in the constellation Cassiopeia there is a Variable Blue Supergaint Star known as Kappa Cassiopeiae. This Star is 37 times the mass of our sun and is traveling at such a high speed that it is creating a “bow shock” with surrounding matter in space. As the star moves through the Milkway at 2,461,000 miles per hour, it compresses interstellar gas and dust to form the red arch in the image above. Stars that are moving at these speeds (relative to surrounding space) are classified as Runaway stars and provide a unique opportunity for Astronomers to study the properties of stars.
