a vast amount of galaxies of various shapes and sizes. A galaxy is defined as a system of millions or billions of stars with gas and dust held together by gravitational attraction. There are several types of galaxy types: elliptical, spiral and irregular. Spiral galaxies are galaxies which usually have a large mass in the middle with arms branching off of it containing stars and star systems (Swinburne University of Technology, n.d.). All of the objects orbiting the centre of the galaxy must…
Researches have located a truly colossal black hole at the heart of the recently discovered galaxy known as SAGE0536AGN. The oddly enormous supermassive black hole is approximately thirty times larger than it should be and astronomers cannot seem to figure out why. Researchers from U.K.’s Keele University and the University of Central Lancashire have recently discovered a new black hole that defies all logic. The galaxy, which houses this supermassive black hole, was discovered using NASA’s…
Stellar Dawning Coalescence The early Universe was filled with roaming clouds of gas, namely hydrogen, and dust. In many cases, the ingredients for stars laid dormant for millions, perhaps billions of years until an event disturbed them ("Star birth", 2013). As Isaac Newton states in his first law of motion, “An object will stay at rest or travel at a constant velocity until acted on by a force,” and the same remains true even at the massive scales of the Universe. These clouds of gas and dust…
I would like to gain knowledge regarding galaxies, black holes, and exoplanets. A galaxy is a system that contains millions of stars, gas and dust held together by gravitational attraction. A black hole is a place in space where the gravitational force is immense, making the escape of matter and radiation impossible. An exoplanet is a planet that orbits a star, other than the sun, beyond our solar system. By choosing these targets, I wish to learn about how the first galaxies were formed, why…
Have you ever wondered how stars are formed, how massive they are, or even how they perish. 1. Well most massive stars are the shortest lived.2. A star's life expectancy depends on its size. 3.Most star’s take millions of years to perish. We should be learning about stars because stars are something that most humans don't know about, most don't know how they form, how they perish, or even how massive they are. Most massive stars are the shortest lived. A star's life expectancy depends on its…
As a young girl, my neighborhood friend and I would stargaze consistently throughout the summer. We would lay on her trampoline, look at the stars, and have detailed conversations about space. While we were lying down in the palpable darkness, we would identify as many constellations as possible. Although, the main night that stands out to me, was when her father brought his telescope outside to give us a close viewing of Jupiter. That moment still affects me today since I have continued to…
A Stars lifecycle can span from millions to trillions of years depending on the size of the star. Starting from a cloud of gas and dust then transforming into something that we on earth see every day as our own Sun then finally collapsing upon itself and eventually dying. Stars have been a major part of the development of life on Earth and will continue to dictate how we live our lives. Without these enormous balls of gas and energy life as we know it would cease to exist. This is regrettably…
discovered that many patterns emerged linking the mass of a star to its lifespan. From the noted trends and correlations they formed what is now known as the Hertzsprung Russell Diagram or commonly referred to as the HR Diagram. The HR Diagram is used as an important tool in the study of astrophysics. Specifically it is a graphical tool that Hertzsprung and Russell formed for astronomers to use to measure the different characteristics of a star, i.e. luminosity, spectral type, colour,…
Quod phoenix est ut incenderent existo.’-The phoenix must burn to emerge. In accordance to this statement everything in this cosmos at one point of time must be reborn to emerge stronger than ever. There is a specific period in life when humans at a certain time become retrospective. Rebirth or The Renaissance during the Quattrocento period in Italy epitomized this phenomenon. Classical antiquity and the interest and learning that accompanied it was reborn after the Middle Ages in a period…
A Pentacle is very similar to a pentagram. A pentagram is a five-pointed star, each point representing one of the five elements, earth, air, fire, water, and akasha also known as spirit. A pentacle is a pentagram encased in another shape; most commonly a circle but it can any shape, a pentagon, a triangle, or another star. The word its self is broken down into two pieces, “penta” meaning five sided, and “cle” referencing the circle. It is a symbol cloaked in history and dripping with meaning.…
