Spiral Galaxies The most common type of galaxy is called a spiral galaxy.. Not surprisingly, spiral galaxies look like spirals, with long arms winding toward a bright bulge at the center.

General Astronomy/Print version The Milky Way appears about equally bright in a band around the sky. The Milky Way is a spiral galaxy which formed about 14 billion years ago, and looks like a large pinwheel rotating in space. Dust, gas and stars fan out from the center of the Milky Way in long spiraling arms. Our galaxy is made of clouds of dust and gas called nebula, stars, comets, meteors, asteroids, and planets. Our own Sun and Solar System also are a part of the Milky Way Galaxy; our Solar System is about 26,000 light-years from the center of the Galaxy. The Sun travels around the center of the Milky Way, taking about 250 million years to complete an orbit. All objects in the Milky Way rotate around the Galaxy's center.

What is the Closest Galaxy to the Milky Way? It has a roughly elliptical shape and is thought to contain as many stars as the Sagittarius Dwarf Elliptical Galaxy, the previous contender for closest galaxy to our location in the Milky Way. In addition to the dwarf galaxy itself, a long filament of stars is visible trailing behind it.

- In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a bulge, a disk containing spiral arms, and a halo.. Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.

Andromeda Galaxy The Andromeda is a spiral galaxy, like the Milky Way, with widespread projections of stars entwined around a distinct center. One difference is that the Andromeda galaxy is larger than the Milky Way and emits more light. The galaxy is centered on a shining protuberance.

Milky Way The Milky Way is the galaxy that contains our Solar System. The descriptive milky is derived from the appearance from Earth of the galaxy – a band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος. From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first ...

Spiral Galaxies Spiral galaxies are further classified by how tightly their spiral arms are wound. A galaxy with very tightly wound arms, such the left galaxy in the list above, would be called type a. galaxy A type b galaxy has more loosely wound arms.

What Galaxy Does the Milky Way Belong To? Quick Answer. The Milky Way is itself a galaxy. It does not belong to a galaxy, but to a galaxy cluster known as the Local Group. The Local Group is composed of over 30 galaxies including the Milky Way, the Andromeda Galaxy, the Triangulum Galaxy and several dwarf and irregular galaxies. Continue Reading.

Types of Galaxies Spiral galaxies are the most common type in the universe. Our Milky Way is a spiral, as is the rather close-by Andromeda Galaxy. Spirals are large rotating disks of stars and nebulae, surrounded by a shell of dark matter.

Why Is Our Galaxy Called The Milky Way? First, let’s back up a bit and talk a bit about what the Milky Way actually is. Astronomers believe it is a barred spiral galaxy — a galaxy with a spiral shape that has a line of stars across its middle, as you can see in the picture above.If you were to fly across the galaxy at the speed of light, it would take you an astounding 100,000 years.irst, let’s back up a bit and talk a bit about what the Milky Way actually is.

Milky Way At the low end of the estimate range, the mass of the Milky Way is 5.8×10 solar masses (M☉), somewhat less than that of the Andromeda Galaxy. Measurements using the Very Long Baseline Array in 2009 found velocities as large as 254 km/s for stars at the outer edge of the Milky Way.

Milky Way The Milky Way is a barred spiral galaxy with a diameter between 100,000 light-years and 180,000 light-years. The Milky Way is estimated to contain 100–400 billion stars. There are probably at least 100 billion planets in the Milky Way.

Light As A Cosmic Time Machine by Andrew Fraknoi The nearest large galaxy to the Milky Way is the Andromeda Galaxy. Sometimes astronomers call it M31, by its number in the famous Messier catalog of fuzzy celestial objects. The Andromeda (pronounced An drah' mid a) Galaxy lies about 2 1/2 million light years from Earth.

Types and Classification of Galaxies 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.

Milky Way From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe.

Milky Way The Milky Way is a barred spiral galaxy that has a diameter usually considered to be about 100,000–120,000 light-years but may be 150,000–180,000 light-years. The Milky Way is estimated to contain 100–400 billion stars. There are likely at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 27,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm.

What galaxy does the milky way belong to? The Milky Way is our galaxy. It is close to the Local Super Cluster of galaxies, Virgo 1. The Super Cluster is a giant area of many galaxies, that head toward each other, but… do not necessarily collide with each other.

Barred spiral galaxy A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars.Bars are found in approximately two-thirds 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.Our own galaxy, the Milky Way, is classified as a barred spiral galaxy.ars are thought to be temporary phenomena in the lives of spiral galaxies; the bar structures decay over time, transforming galaxies from barred spirals to more regular spiral patterns. Past a certain size the accumulated mass of the bar compromises the stability of the overall bar structure.

What is the Closest Galaxy to the Milky Way? The Andromeda Galaxy (M31) is the closest spiral galaxy to us, and though it’s gravitationally bound to the Milky Way, it’s not the closest galaxy by far – being 2 million light years away. Andromeda is currently approaching our galaxy at a speed of about 110 kilometers per second.

Andromeda galaxy Parallax. The Andromeda Galaxy, also known as M31, or NGC 224 is a large barred spiral galaxy (type Sb), the nearest of such to the Milky Way, and situated within the same galactic cluster called the Local Group. It appears to be within the constellation Andromeda, hence its name.

Solar System The Milky Way is a barred spiral galaxy and is part of the Local Group of galaxies. Ours is merely is one of billions of galaxies in the observable universe. Our sun is 25,000 light years from the center of the Milky Way. The oldest star in the galaxy is 13.2 billion years old. The stellar disk of the Milky Way Galaxy is approximately 100,000 light years in diameter and is about 1,000 light years thick. It is estimated to contain up to 400 billion stars.

Galaxies 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.
