is the milky way an elliptical galaxy

What features of the Milky Way helped you determine this answer? The galaxy has so much mass that it is gravitationally lensing more distant galaxies, which appear as arcs around the galaxy. Second, the Milky Way is a barred spiral galaxy; unlike typical spiral galaxies, barred spiral galaxies have flat discs in their centers. The Galaxy the milky Way is a Barred spiral galaxy but soon to be an elliptical galaxy when Andromeda collides with the Milky Way. The considered satellite for Milky Way is letter D: Copernican Dwarf Elliptical or Sagittarius Copernican Dwarf Elliptical. Most of these small galaxies may not be related to other ellipticals.

Our experts can answer your tough homework and study questions. Irregular Galaxy. Minor galactic mergers involve two galaxies of very different masses, and are not limited to giant ellipticals. What are some physical characteristics of... What do spiral and elliptical galaxies have in... What are the different types of galaxies? They are spherical or ovoid masses of stars, starved of star-making gases. SBa. Every massive elliptical galaxy contains a supermassive black hole at its center. [23], Galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile, Learn how and when to remove this template message, The Distribution of Intensity in Elliptical Galaxies of the Virgo Cluster. General Characteristics of Elliptical Galaxies . These are similar to their smaller brethren, but more diffuse, with large haloes that may as much belong to the galaxy cluster within which they reside than the centrally-located giant galaxy. What features of the Milky Way helped you determine this answer? The Andromeda Galaxy is approaching the Milky Way at nearly a quarter million miles per hour. Services, Galaxy Formation: Spiral, Elliptical & Irregular Galaxies, Working Scholars® Bringing Tuition-Free College to the Community. [15] This range is much broader for this galaxy type than for any other. The "Milky Way" is the name given to the galaxy in which we reside. Cranking up the power will reveal M86’s starlike core. Most elliptical galaxies are composed of older, low-mass stars, with a sparse interstellar medium and minimal star formation activity, and they tend to be surrounded by large numbers of globular clusters. What is a spiral galaxy? Elliptical galaxies host less (or no) star birth than spiral galaxies like the Milky Way. III. Furthermore, there is very little interstellar matter (neither gas nor dust), which results in low rates of star formation, few open star clusters, and few young stars; rather elliptical galaxies are dominated by old stellar populations, giving them red colors. They have the most variation in size of any type of galaxy, as they can be very large, or extremely small, with some of them being less than 10% of the size of our galaxy, the Milky Way.They can often be mistaken for stars due to their compact appearance. Do all galaxies follow the law of gravity? It is a fairly typical barred spiral with four major arms in its disk, at least one spur, and a newly discovered outer arm. Such major galactic mergers are thought to have been more common at early times. Observations of 46 elliptical galaxies, 20 classical bulges, and 22 pseudobulges show that each contain a black hole at the center. The Milky Way galaxy is best described as A an elliptical B a spiral C an irregular D a globular 2. Galaxies were also formed as a result of this explosion. What is the Milky Way? All rights reserved. Gazing skyward from our vantage point on and around Earth, there are clear signs that the Milky Way is a spiral galaxy. The elliptical galaxy is one of the most intriguing parts of our universe. and low level star-formation. The Milky Way has more than 200 billion stars. The Milky Way is not an elliptical galaxy, but a spiral galaxy. II, More isotropic oblate rotators in elliptical galaxies. The Milky Way galaxy, depending upon an unknown tangential component, is on a four- to five-billion-year collision course with the Andromeda Galaxy. Spiral Galaxy . Modern galaxy classification schemes lean toward M86 as a lenticular (lens-shaped) galaxy, rather than a strict elliptical. Elliptical (E) galaxies are, together with lenticular galaxies (S0) with their large-scale disks, and ES galaxies[2][3][4] with their intermediate scale disks, a subset of the "early-type" galaxy population. At the large end of the elliptical spectrum, there is further division, beyond Hubble's classification. The galaxy's spiral … Elliptical galaxies are characterized by several properties that make them distinct from other classes of galaxy. Is The Milky Way A Spiral Galaxy Or An Elliptical 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. Elliptical galaxies are shaped like ellipses (stretched circles). The largest galaxy ever discovered in our Universe is the supergiant elliptical galaxy designated as IC 1101. The first clue can be obtained by simply gazing at the stars embossed onto the dark, night sky. The Milky Way is itself on a collision course with our nearest neighbor, the Andromeda galaxy. The spiral galaxies are the most common type of galaxies observable in the universe (around 75%), and our own galaxy, the Milky Way, is also a spiral galaxy. Galaxy with no particular shape. Round galaxy. Question: 4. 5. ", https://en.wikipedia.org/w/index.php?title=Elliptical_galaxy&oldid=998391084, Articles lacking in-text citations from March 2015, Articles with unsourced statements from September 2018, Articles lacking reliable references from September 2018, Articles with unsourced statements from March 2015, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 January 2021, at 04:49. Dwarf spheroidal galaxies appear to be a distinct class: their properties are more similar to those of irregulars and late spiral-type galaxies. All other trademarks and copyrights are the property of their respective owners. Simulations and observations show that when two galaxies of similar mass collide, they form an elliptical galaxy without any spiral structure. Elliptical galaxies are preferentially found in galaxy clusters and in compact groups of galaxies. [citation needed], The traditional portrait[citation needed] of elliptical galaxies paints them as galaxies where star formation finished after an initial burst at high-redshift, leaving them to shine with only their aging stars.
