Setting: Space (Milky Way and Beyond) Themes: Solar System, Astrology, Galaxies. Genre (assignment tags): ETEC Class 6, Middle School Science, Middle School Non-fiction. Summary: A part of a long running science series aimed at Middle Grade readers by Seymour Simon, Galaxies examines the Milky Way and beyond.4/5. a venn diagram to compare galaxies, based on observed properties. the process skills used in this activity are comparing and contrasting, and categorizing and listing. this activity can be used to teach students about galaxies, or as an assessment, following a study of galaxy types. Find the Right Circle ( continued on page).

The type-cD galaxy (also cD-type galaxy, cD galaxy) is a galaxy morphology classification, a subtype of type-D giant elliptical galaxy. Characterized by a large halo of stars, they can be found near the centres of some rich galaxy clusters. They are also known as supergiant ellipticals or central dominant galaxies. Perhaps the most conspicuous activity in galaxies occurs in their nuclei, where evidence suggests that in many cases supermassive objects—probably black holes —lurk.

However, this lesson will focus on galaxies in general, rather than one specific galaxy. The following activities and games will help your students learn more about galaxies. Comparing Galaxy Types. Search the world's most comprehensive index of full-text books. My library.

It reports on theoretical research and observational data on active galactic nuclei: The enigma of the nuclei of galaxies with their central "monster" driving the vast range of activity observed in quasars, radio galaxies, Seyferts, starburst galaxies and even our own Galaxy are explored in this volume.

Topics covered include: the impact of recent measurements in the infrared and radio region on our knowledge of thenucleus of our Galaxy; the spectra and classification of active galactic nuclei, the properties of their host galaxies, their cosmological distribution and evolution, the role of stars and thehydrodynamics of the interstellar medium in the nuclei; the description of the inner parsec of a standard active galactic.

Books. The Galaxy's Edge Universe is established by the nine book series of the same name, and follows the Galaxy's spiral into chaos at the hands of Galactic Republic officials and an enigmatic, would-be emperor with a dark power from beyond the Edge, intent on saving a corrupt galaxy-spanning civilization from itself.

Unveiling Galaxies is informative, well-written, and well-researched, and provides a superb read of the process of discovery in science.' Ronald J. Buta - University of Alabama 'In this beautifully clear, reflective, and almost non-mathematical book, Jean-René Roy explains how we came to understand that galaxies are the building blocks of the Author: Jean-René Roy.

The stars, clusters, and nebulae in the disk rotate around the center of the galaxy. In our Galaxy, it takes million years for our sun to make a full revolution around the center. In addition to the disk, spiral galaxies also have a “bulge”, which is a large, squashed sphere surrounding the galaxy’s center.

Buchanan High School Teacher Web Site. Jan 11,  · An artist's concept of the central region of an active galaxy. Active galaxies are galaxies that have a small core of emission embedded at the center of an otherwise typical galaxy. This core is typically highly variable and very bright compared to the rest of the galaxy.

Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much dark matter as all the stars and gas put together. And it’s all held together by gravity. Like more than two-thirds of the known galaxies, the Milky Way has a spiral shape.

At the center of the spiral, a lot of energy and, occasionally. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few hundred million (10 8) stars to giants with one hundred trillion (10 14) stars, each orbiting its galaxy's center of mass.
