V. The Cat’s Eye Nebula One of the most famous nebulae is the Cat’s Eye Nebula (NGC-6543); it was discovered by William Herschel in 1786. NGC-6543 is located in the northern constellation of Draco; it appears as a blooming center with surrounding and expanding rings. The NGC-6543 has a historical importance because it was the first nebula to be studied spectroscopically by the astronomer William Huggins in 1864; this study revealed the distinctions between PNe and the other gaseous nebulae.…

Discussion – Tayla Dorrington Introduction There are 2 major theories about the universe and how it began. These are the steady state and The Big Bang theory. Both theories have an explanation on how our Universe is, how it began and how it works. Both theories have stuff in common but also have many differences that could completely change the way we look at the Universe. The Big Bang Theory has much more evidence supporting it, while the Steady State Theory has been proven wrong. Big Bang…

For devices on Nano scale classical physics usually cannot explain transmission of electron through the insulating barrier with higher potential energy than kinetic energy of the tunnelling electrons and in this case the Heisenberg’s uncertainty principle takes place. Barrier penetration can be explained from Heisenberg’s uncertainty principle: If we were to say a particle cannot enter a barrier, we would actually say this particle is not there, i.e. its position uncertainty is Δx = 0 in the…

too late. As you know, the galactic post office takes 1,000,000 years to deliver to distant galaxies. And since you all are getting further away, I am sorry if the letter does not reach you in time. The universe is changing. In fact, galaxies are moving apart at an ever increasing rate. The gravitational attraction between two galaxies at that distance is too small to have a significant effect, so the galaxies more or less follow the general flow of the expansion. I hope the best from all of…

The Solar System By Krishiv There is always something that you are pondering about. From the periodic table to the circulatory system. But did you know that the majority of people wonder about the Solar System? It is the final frontier, or the one thing that is not fully discovered. There are many unique masses in the Solar System. They range from planets like the earth to rocks such as asteroids, comets, and meteors. But one thing is for certain… every mass has to orbit the sun.…

many questions an average person would ask such as, How was the universe formed, how old is the universe, and will the universe expand forever? The universe is a huge wide open space that holds everything from the smallest particle to the biggest galaxy. Isn't that crazy? For the question many that many were asking, scientifically, about 13.7 billion years ago, a powerful explosion happened called…

H-R Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the…

To me, astronomy is the study of the universe and everything in it. This includes the planets, moons, stars, comets, etc. The major difference found between Muggle astronomy and Wizarding astronomy is that the Muggle world has "laws" that explain what they see in the universe. The study of these laws of the universe in the Muggle world is called "physics". Although these laws do explain a vast majority of what the Muggles see on Earth and in the universe, it may not hold true in the Wizarding…

as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth large size and active galactic nucleus] or supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomer. Messier 81 was first discovered by Johann Elert Bode in 1774.Consequently, the galaxy is sometimes referred…

The messier galaxy is galaxy that is seventeen million light years away. This galaxy can be seen in the constellation Hydra. This galaxy is a spiral pinwheel galaxy and is also one of the brightest galaxies in the sky. The galaxy messier 83 was founded in February 23 in 1752 by Nicolas Louis de Lacaille. Lacaille found the Messier 83 galaxy off of the Cape of Good Hope. In March of 1781 Charles Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on…
