Galaxies are enormous systems in outer space, including our own called the Milky Way. In this lesson, learn the definition of a galaxy, find out about the three different types of galaxies, and. A galaxy is a huge collection of gas, dust, and stars held together by gravity. Most galaxies contain at least a trillion stars. There are trillions of galaxies in the universe. Galaxies are grouped according to shape type. The three galaxy types are elliptical, spiral and irregular.

Enjoy these fun galaxy facts for kids. Learn how about all the different types of galaxies in the universe, the Milky Way Galaxy that Earth sits in, the Local Group of galaxies we are part off, how many galaxies there are in the observable universe and much more. Galaxies were born only a few hundred million years after the Universe was created. At that time, about 13 billion years ago, the galaxies were small and much closer together. The Different Types Of Galaxies. In our universe are four identified types of galaxies. These galaxies are composed of stars, gas and dust held together with gravitational forces. Each galaxy type is named for its shape, making it easy to identify which type of galaxy you are looking at. You may already be familiar with the galaxies: spiral. Galaxy Facts A galaxy is a massive, gravitationally bound system that consists of stars, stellar objects (such as brown dwarfs and neutron stars), nebulae, an interstellar medium of gas and dust, black holes, and an unknown component of dark matter. The material however changes to create all different types of strange stuff that makes up galaxies, stars and planets that all look different to one another. Even right now new Stars are being formed by all this material and gas smashing together. Classroom GROUP THE GALAXIES using Galaxy Trading Cards National Aeronautics and Space Administration Classroom Activity In this activity, students are introduced to. types of galaxies for kids Galaxies are huge groups of stars orbiting a central point. Almost always, that point is a supermassive black hole. Its pull keeps stars clustered together. Spiral galaxies are the most common type in the universe. Our Milky Way is a spiral, as is the rather closeby Andromeda Galaxy. Spirals are large rotating disks of stars and nebulae, surrounded by a shell of dark matter. identify types of features found in galaxies by classifying the photographs into groups, using a classification scheme of their choice. discuss what the classification groups they devised might tell them about galaxies. Galaxies Galore: Spiral galaxies This is an interactive matching activity where students drag color images of spiral and barred spiral galaxies to black and white pictures of identified spiral categories. classified just like ordinary spiral galaxies SBa, SBb, SBc barred Our own milky way is probably an SBb type galaxy, similar to Andromeda, but with a central bar The Antennae galaxies, two separate galaxies in the process of merging. Galaxies colliding with each other is a very common event in our Universe. In fact our very own Milky Way is a product of smaller dwarf galaxies merging to form a larger one. Elliptical Galaxies are generally the largest in the universe but spiral galaxies are often teeming with bright new stars those dusty arms that make up the spiral. There are many galaxies besides ours, though. There are so many, we cant even count them all yet! The Hubble Space Telescope looked at a small patch of space for 12 days and found 10, 000 galaxies, of all sizes, shapes, and colors. The word galaxy brings to mind images of the Milky Way or perhaps the Andromeda galaxy, with their spiral arms and central bulges. These spiral galaxies are what people commonly imagine all galaxies look like. Yet, there are many types of galaxies in the universe and they're not all spirals. To be sure, we live in a spiral galaxy, but there are also elliptical (rounded without spiral arms. Galaxies Types and Classifications The identification of other galaxies, or independent stellar systems, goes back to 1924, when Edwin Hubble found Cepheid variables in. Different types of galaxies include spiral galaxies such as our own Milky Way, rich in dust and gas with stars still forming in their arms; elliptical galaxies devoid of gas, lenticular galaxies and irregular galaxies such our neighbours the Magellanic Clouds and the Sagittarius dwarf galaxy. Types of Galaxies There are four main types of galaxies depending on their shape: Spiral The spiral galaxy has a number of long arms that are spiraling around the center. In the center of the spiral galaxy are older stars while the arms are generally made of new stars. Galaxies are categorised according to their apparent shape. These shapes are typically divided into elliptical, spiral or irregular. Galaxies are classified into three main types: spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies, such as the Milky Way, consist of a flat disk with a bulging center.

The main feature of spiral galaxies is, as their name suggests, their spiral shape. At their center is a very bright circle with tons of old stars. The shapes of galaxies are influenced by their neighbors, and, often, galaxies collide. The Milky Way is itself on a collision course with our nearest neighbor, the Andromeda galaxy. Even though it is the same age as the Milky Way, Hubble observations reveal that the stars in Andromeda's halo are much younger than those in the Milky Way. Astronomy Activity Galaxies Mobile. In this astronomy activity you will create a mobile of the major types of galaxies. Galaxies are groupings of stars. Almost all stars are in located in galaxies. You just clipped your first slide!

There are many different types and shapes of galaxies which we will take about in a minute. The sizes of galaxies range from a few thousand light years across, which would be a small dwarf galaxy, to the biggest of about 300 thousand light years across. Galaxy definition is milky way galaxy used with the. How to use galaxy in a sentence. The fluctuations then produced variations in the dense soup of fundamental particles that seeded the formation of the galaxies. 2: one of the very large groups of stars, gas. Galaxies are a massive collection of stars and dark matter, ranging from a few million stars (dwarf galaxies) to hundreds of billions of stars (giant galaxies). Most galaxies are disk shaped and are tens of thousands of light years in diameter. Astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular. The Facts While a solar system consists of all of the objects that orbit a particular star, a galaxy is a larger unit of astronomical assemblage. Types of Galaxies Common Core Reading and Writing Activities is a common core activity designed to teach students about the the types of galaxies.

Hubble noted that some galaxies, like the M31 Andromeda Galaxy, appeared as disks and had arms of stars and dust which. This artist's concept illustrates the two types of spiral galaxies that populate our universe: those with plump middles, or central bulges, and those without them. New observations from NASA's Spitzer Space Telescope provide strong evidence that the slender, bulgeless galaxies can, like their chubbier counterparts, harbor supermassive black holes. The first attempts at systematic catalogues of galaxies were made in the 1960s, with the Catalogue of Galaxies and Clusters of Galaxies listing 29, 418 galaxies and galaxy clusters, and with the Morphological Catalogue of Galaxies, a putatively complete list of galaxies with photographic magnitude above 15, listing 30, 642. galaxies involved in the interaction, their masses and types, how close they are, and how they approach each other. The Antennae galaxies are an example of two spirals Galaxy Types of galaxies: Almost all current systems of galaxy classification are outgrowths of the initial scheme proposed by the American astronomer Edwin Hubble in 1926. In Hubbles scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes: ellipticals, spirals, and irregulars. Types and Classification of Galaxies. There are three main types of galaxies: Elliptical, Spiral, and Irregular. Two of these three types are further divided and classified into a system that is now known the tuning fork diagram. When Hubble first created this diagram, he believed that this was an evolutionary sequence as well as a classification. What are the different shapes of other galaxies? These are some facts you should be familiar with when answering the questions you will find in. Key points: Basic types of galaxy spiral, barred, elliptical, irregular; types vs. distance (how young galaxies differ from those around us) Spiral galaxies are the most intriguing visually, But in fact galaxies come in many shapes and sizes. Spiral galaxies are the most familiar in popular cultureafter all, our own Milky Way is a spiral. A spiral galaxy has a bright bulge in the center with spiral arms that radiate outward in a plane, giving the whole galaxy a shape somewhat like a flattened pinwheel.
