Protostar This is the stage in which the star begins to form after the collapse of the interstellar cloud. It happens in small molecular clouds that can be referred to as dense cores. In the beginning the dense core has a level of balance between its own gravitational forces (self-gravity)‚ and both the magnetic pressure‚ and gas pressure. The self-gravity acts to compress the dense core‚ while the gas‚ and magnetic pressures act to inflate it. The core’s self-gravity will eventually overwhelm it

Parallax * Parallax is the apparent movement of a nearby object when it’s viewed from 2 different points. * The farther the star the smaller the angle * Distance from one side of earth orbit to other is 300km. * distance from earth to sun is 1 AU * Can only measure close stars reliably. * Parallax is very small due to distance to stars. Makes it harder to measure accurately. * Relies on no assumptions‚ only earth’s geometry around the sun. * Uses simple trigonometry

In 1999‚ John Gizis‚ a professor of physics and astronomy at the University of Delaware‚ discovered one of the most important stars in NASA’s history. Sadly this discovery wasn’t noticed until 2016. This discovery was the “Trappist-1” system. The discovery of the Trappist system helps build upon the fact of we are not alone in the universe. Trappist-1 includes a sun slightly larger than jupiter and seven orbiting planets‚ Most planets have sizes and masses comparable to the earth‚ and the size

Ufos Have you ever seen a random unidentifiable thing in the air? What about a saucer shaped aircraft? These things can be grouped as UFOs or unidentified flying objects. UFOs are thought to be carrying extraterrestrial life. UFOs are a major subject of interest because of how they look‚ famous sightings‚ and possible explanations. UFOs come in all shapes and sizes. Some that are reported even are said to have an invisible look to them. In Benjamin Radford’s article “UFO Sightings and News” a majority

The galaxy‚ called W2246-0526 is the most luminous galaxy known‚ which means that if all galaxies were the same distance from Earth it would appear the brightest. This galaxy was formed over a billion years ago after the Big Bang. A recent discovery shows that this galaxy is releasing tremendous amounts of turbulent gas‚ which has never been seen before from a galaxy of this kind. The galaxy is tearing itself apart‚ because the momentum of the particles of light deposited in the gas are pushing gas

This blue mould was in fact the natural form of penicillin which Fleming realised was an effective way of killing bacteria. Eckert and Mauchly During the Second World War the Us Navy were looking for ways of improving the accuracy of their artillery shells. Eckert‚ an engineer‚ and Mauchly‚ a physicist produced the world’s first computer. Eniac was huge. When it was turned on‚ the lights in the local

impossible. I had to read more. I am not done with the book yet though. I felt like I was reading an anime. I could picture the scene of what I was reading so clearly that it felt like my body was there. I loved the way they represented what happened to Arthur on planet earth in a gross way where the house to be demolished for a pathway was the earth in the galactic space. I loved the idea of having a fancy galaxy with a president who has two heads and three arms. I can’t imagine what it will be to have

Music has been known as a universal language that creates a profusion of knowledge and understanding between others. In this case‚ I will be using music to connect different characters in the novel I am Number Four‚ and show how they have changed and shaped themselves through the first portion of the book. Some of these characters are John‚ an alien trying to survive on Earth after his planet gets destroyed‚ Henri‚ John’s guardian and protector working on Earth towards the ultimate goal of saving

Todays lecture will focus on the teachings of the highly esteemed Aristotle. Specifically we will be exploring two major questions that are highly important when comparing the great Aristotle to the heretic Galileo. The major questions that we will delve into today are: Does the Earth move? as well as‚ Is the universe bounded‚ as Aristotle maintained‚ or is it infinite? Aristotle firmly believes that the Earth is immovable‚ he backs his claim with both science and the word of our Lord. As the lowly
