    appears to be empty, it is actually filled with matter known as the interstellar medium, approximately ninety-nine percent of the interstellar medium consists of gas and the remaining one percent is dust. Clouds of interstellar medium are called nebula, derived from the Latin word for cloud (What is the Interstellar Medium?, n.d.). Nebulas are formed when gravitational attraction clumps together parts of the interstellar medium (Villanueva, 2010). There are several types of nebula, which are differentiated

    details. All things have a life cycle of creation, life, and dying, including the stars. A star's birth starts with a interstellar cloud. A interstellar cloud, or a interstellar medium, is a cloud made of hydrogen gas and dust. Also, the interstellar cloud is a filled space between the other stars, that has a rattling low density (Interstellar Medium). A star forms from a interstellar cloud by combining with other atoms. With the temperature being, nothing to just above zero degrees, the atoms of the

    The Birth of a Star

    A star is a self-radiant divine body consisting of a mass of gas held together by its own gravity. The birth of a star begins inside a molecular cloud. Stars form inside these somewhat dense concentrations of interstellar gas and dust. The process of star formation has long been a mystery because of viewing limitations. Large amounts of small solid particles blocked our view of the stars which are beyond the molecular cloud. Infrared technology now provides some insight on how a star is formed

    Cosmic rays are to scientists much like photons are to astronomers. Just as astronomers use light (or photons) to view our galaxy and beyond, scientists use cosmic rays to infer useful properties about our galaxy. In fact, cosmic rays offer one of the few ways in which scientists can actually sample real matter outside of our solar system. By identifying the various nuclei that are dispersed throughout our Galaxy, scientists hope to unravel the mechanisms that actually produce these nuclei -- from

    dust and gas floating in space. The word nebula is Latin and means cloud. Originally the word nebula referred to any extended astronomical object, not including comets, planets, or satellites. But over time the word nebula became reduced to mean interstellar cloud of dust and gas. Calling it that does not do a nebula justice. Most nebulae are commonly made up of hydrogen and helium gasses, dust, and plasma. Nebulae are the building blocks of our universe; they contain all the things stars need to

    disproven. Philosopher Robert Millikan observed that instead of an intrinsic field, Hess was studying a mutability of photons and electrons. He concluded that these “cosmic rays,” which he named these fluxes, were not telluric, but instead came from interstellar space. Millikan explained these happenings as Compton Scatterings, gamma ray scatterings named after Arthur Compton. Highest energy cosmic rays have been studied for about a century now... ... middle of paper ... .... With advancements in our

    Question 1: List and briefly describe each of the six steps involved in the formation of the solar system. Response: Step 1: Gravitational Collapse An interstellar cloud of gas that is known as the solar nebula collapsed under its own gravity. The collapse may have been caused by a cataclysmic event. After that, gravity allowed the collapse to continue. This lead to the heating, spinning and flattening of the solar nebula. The Sun formed in the center of the collapsing solar nebula where the

    Do stars have the ability to explode? How and why does this happen? Stars do have the ability to explode. When stars explode it is called a supernova. They are the most energetic events that occur in our universe (Chaisson and McMillan, 548) . Supernovas occur when the fusion inside the stars core slows down and under the force of gravity the core to starts to shrink, thus causing the star to become much hotter and denser. When the fusion process ends it leaves mainly iron inside of the core (Dove)

    Purpose: to become familiar with the image analysis program and to develop an understanding to the size and age of planetary nebulae Procedure The first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses

    as well as several other interesting phenomena such as Bok globules, and the hourglass nebula. It is these regions of the nebula that make it a continuous area of interest and study for astronomers. Messier 8, nicknamed the Lagoon Nebula is an interstellar cloud located in Sagittarius, discovered by John Flamsteed in 1680. It is one of the few nebulae that can be seen by the naked eye. It was given its nickname by Agnes
