The spiral galaxies were the first type of galaxies to be observed by human, and that was our neighboring galaxy, the Andromeda In general, spiral galaxies contain roughly 10 9 to 10 11 solar masses and have luminosity between 10 8 and 2×10 10 solar luminosity The diameter of the spiral galaxies can vary from 5 kilo parsecs to 250 kiloThe spiral galaxy, NGC 4622 (also called Backward galaxy), lies approx 111 million light years away from Earth in the constellation CentaurusNGC 4622 is an example of a galaxy with leading spiral arms In spiral galaxies, spiral arms were thought to trail;Spiral galaxies—of which the Milky Way system is a characteristic example—tend to be flattened, roughly circular systems with their constituent stars strongly concentrated along spiral arms These arms are thought to be produced by traveling density waves, which compress and expand the galactic material

Galaxy 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 Hubble's scheme, which is based on the optical appearance of galaxy images on photographic plates, galaxies are divided into three general classes ellipticals, spirals, and irregularsGalaxies are collections of stars, dust, and gas bound together by gravity This lesson will cover the structures and types of galaxies, including spiral, elliptical, and irregular galaxiesSpiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequenceMost spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulgeThese are often surrounded by a much fainter halo of stars, many of which reside in

Which characteristics describe a spiral galaxy?Spiral Galaxies Spiral galaxies like NGC 3310 (right) have two distinct regions The disk of the galaxy contains the spiral arms The disk is a region of star formation and has a great deal of gas and dust It is dominated by young, blue Population I stars The central bulge is devoid of gas and dustA spiral galaxy is simply I I0 = e−r/rd (701) where I0 is the galaxy's central surface brightness in units of ergs cm−2 s−1 arcsec−2 and r d is the scale length of the exponential However, not all spiral galaxies have a bulge, and in some galaxies (such as M31), a decomposition into a de Vaucouleur bulge plus an exponential disk

Spiral galaxies have diameters ranging from ,000 light years to over 100,000 light years Its masses are estimated to range from 10 billion to 10 trillion times the mass of the Sun The Milky Way, where the solar system is located, is a large and massive spiral galaxyMost spiral galaxies contain a central bulge surrounded by a flat, rotating disk of stars The bulge in the center is made up of older, dimmer stars, and is thought to contain a supermassive blackOut Milky Way galaxy is a spiral galaxy and it has a center area with a starry bar Lenticular Galaxies These galaxies are called "lenticular" because they look more like lenses They have a thinner, rotating disk of stars and also have a middle bulge, but no spiral arms They share characteristics with elliptical galaxies in that they

Seyfert Galaxies About Characteristics What Makes Them Special

A spiral galaxy is simply I I0 = e−r/rd (701) where I0 is the galaxy's central surface brightness in units of ergs cm−2 s−1 arcsec−2 and r d is the scale length of the exponential However, not all spiral galaxies have a bulge, and in some galaxies (such as M31), a decomposition into a de Vaucouleur bulge plus an exponential diskA spiral galaxy is a type of galaxy on the Hubble sequence classification scheme There are six main types of spiral galaxies, and they are Sa, Sb, Sc, SBa, S and S A spiral galaxy has a spiral like structure and will have welldefined arms extending outwards All spiral galaxies have a supermassive black hole in the very center of theirSpiral galaxys are divided into three main types depending on how tightly wound their spiral arms are Sa, Sb and Sc Sa galaxies have very tightly wound arms around a larger central nucleus Sc galaxies have very loosely wound arms around a smaller nucleus Sb's are between, having moderately wound arms around an average sized nucleus Spiral galaxies have a lot of gas, dust and newly forming stars

Spiral galaxies are classified into several different types, depending on the characteristics of certain parts of their galaxy Specifically, this lesson will go over Hubble's classificationExplain your reasoning Elliptical are made up of the cooler main sequence and/caption As its name implies, a barred spiral galaxy is a spiral galaxy with a bar through the center Hubble introduced the 'tuning fork' scheme for describing the shapes of galaxies

Science And Reason Spiral Galaxies Are Taking Over

Spiral galaxies—of which the Milky Way system is a characteristic example—tend to be flattened, roughly circular systems with their constituent stars strongly concentrated along spiral arms These arms are thought to be produced by traveling density waves, which compress and expand the galactic materialSpiral galaxies are classified into several different types, depending on the characteristics of certain parts of their galaxy Specifically, this lesson will go over Hubble's classificationTypes of Galaxies There are four distinct types of galaxies in the universe, elliptical, spiral, barred spiral, and irregular Although these are the four main types, there are various types of galaxies and the way in which they are classified is by their shape A galaxy is a cluster of stars, gas, and dust that are kept together by the force of gravity

General characteristics The light profile of spiral galaxies is less concentrated than that of elliptical galaxies Towards the center of the spiral galaxy the stars are redder and older, while in the arms they are blue and hot, because there is a high rate of star formation, very hot at the beginning of their lifeA spiral galaxy has a flat, spinning disk with a central bulge surrounded by spiral arms That spinning motion, at speeds of hundreds of kilometers a second, may cause matter in the disk to takeA barred spiral galaxy is a spiral galaxy with a central barshaped structure composed of stars Bars are found in about half of all spiral galaxies Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well The Milky Way Galaxy, where the Solar System is located, is classified as a barred spiral galaxy
