The Whirlpool Galaxy is a spiral galaxy, pretty much like our own Milky Way and neighbor Andromeda. 2 A spiral galaxy can be identified as a spinning, flat disk with spiral arms and a bulge in the center. The spinning is at hundreds of kilometers per second and this may be what causes the disk to look like a spiral. Out Milky Way galaxy is a spiral galaxy and it has a center area with a starry bar Now that the concept of a spiral galaxy is clear, let's have a look at some of its facts which would help to simplify this concept a little more. 1. In 2005, it was confirmed that our own galaxy, the Milky Way is an example of a barred spiral galaxy. 2 [/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. Within this, stars of different sizes, ages and temperatures travel around the middle of the galaxy in enormous sweeping bands called spiral arms. The shape of the Milky Way is always changing, but very slowly. Compared with other galaxies, our galaxy, the Milky Way is relatively large. It measures approximately 100,000 light years across

Interesting Facts about Spiral Galaxy CosmosU

  1. An elliptical galaxy is a type of galaxy on the Hubble sequence classification scheme. It's estimated that 60% of all galaxies in the observable universe are elliptical galaxies. There are eight main types of elliptical galaxies, and they are classified between E0, E1, E2, E3, E4, E5, E6 and E7
  2. Facts about Elliptical Galaxies elaborate a type of galaxy, which has featureless image and ellipsoidal shape. It does not have much structure. However, this galaxy has a three dimensional shape. The elliptical galaxy is very different from the flat spiral galaxies for the latter features structure and organization
  3. The galaxy is a barred spiral galaxy — together, its stars form a spiral shape with a bar-shaped center — with a twist: streamers of stars that seem to drift like jellyfish tentacles
  4. The nearest spiral galaxy to the Milky Way is Andromeda, it is 2.5 million light years from Earth. The Andromeda galaxy is the furthest object that can be seen with the naked eye. At the center of most galaxies there is a supermassive black hole which can be millions of times more massive than our sun
  5. The Milky Way is a bath spiral galaxy: This expands in an area of about 120000 light-years across. With a central bulge of about 12000 light-years thick. If you were to see the entire galaxy from a side view, you would notice that it is actually warped in shape. The Milky Way's two neighboring galaxies cause this wrapping according to scientists
  6. d away. That said, let's look at 40 interesting Milky Way galaxy facts. Fact 1. The Milky Way was born about 12.5 billion years ago and has been growing ever since. Fact 2. According to scientists, about 7 new stars are born in the galaxy every single year. Fact 3
  7. 2 Twin Galaxies. While the Milky Way might be unique in many ways, it's safe to say it's not exactly rare. We already mentioned that spiral galaxies are one of the most common types in the universe; add to that the fact that there are around 170 billion visible galaxies, and it wouldn't be a stretch to imagine that there could be a few galaxies out there very similar to our own

Chandra observations (purple) have, in fact, revealed three of the oldest supernovas ever detected in X-rays, giving more credence to its nickname of the. Fun Facts about Galaxies. The word galaxy comes from the Greek word for milky. Some scientists think that most of the mass of a galaxy is made up of a mysterious substance called dark matter. It is thought that there is a massive black hole in the center of galaxies

Spiral galaxies have a dense nucleus and multiple arms. Elliptical galaxies are round/oval in shape. These are smaller than spiral galaxies, and have less dust. The characteristic feature of elliptical galaxies is that new star formation is a rarity. Elliptical galaxies are commonly found in huge clusters of galaxies Spiral galaxies are among the most beautiful and plentiful galaxy types in the cosmos. When artists draw galaxies, spirals are what they first visualize. This is likely due to the fact that the Milky Way is a spiral; as is the neighboring Andromeda Galaxy. Their shapes are the result of long galactic evolution activities that astronomers are still working to understand Other articles where Barred spiral galaxy is discussed: galaxy: SB galaxies: spectra, and distributions of the barred spirals tend to be indistinguishable from those of normal spirals. The subclasses of SB systems exist in parallel sequence to those of the latter

Galaxy Facts. Galaxy Facts. 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. Interesting Galaxy Facts IC 342 is an 8th magnitude face-on intermediate spiral galaxy that's located in the faint northern constellation of Camelopardalis. Since positioned only 10 degrees from the galactic equator it's obscured heavily by Milky Way dust. As a result, this galaxy wasn't even discovered until famed British amateur astronomer William Frederick Denning found it in 1895 The Milky Way is a barred spiral galaxy that has curved arms that spin out from its center. Astronomers discovered it was barred (meaning the center is bar-shaped) rather than an ordinary spiral galaxy (meaning the center is a spherical bulge) in the 1990s. It is 100,000-120,000 light-years in diameter.

  4. An irregular galaxy is a galaxy that does not have a distinct regular shape, like a spiral or an elliptical galaxy.. Irregular galaxies do not fall into any of the regular types of the Hubble sequence.They do not have a bulge in the centre, nor any trace of spiral structure. They are quite common: they may make up a quarter of all galaxies

A 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 take. Irregular galaxies have no particular shape. They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright. The Large and Small Magellanic Clouds are examples of irregular galaxies Key Facts & Summary. There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features. The most common type of galaxy found throughout the universe is the. Elliptical galaxies are also named because of their shapes. Elliptical galaxies range from circular (remember, a circle is an ellipse!) to long, narrow, and cigar-shaped. Elliptical galaxies are denoted by the letter E. They are also given a number from 0 to 7. An E0 galaxy looks like a circle. An E7 galaxy is very long and thin

Galaxies Facts & Information A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. Galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular. Browse below our range of galaxy information include the types, names and locations As this article points out, supercomputer simulations have shown that the spiral arms of galaxies are not transient, random formations, but are self-perpetuating, persistent, and surprisingly long lived. The spiral structure is not just a chance happening. Spiral galaxies are probably the most common kind of galaxy in the universe (our own Milky Way galaxy is a spiral galaxy) An elliptical galaxy is a galaxy having an ellipsoidal shape, and a smooth, nearly featureless brightness profile. They are one of the three main types of galaxy originally described by Edwin Hubble in 1936. The others are spiral and lenticular galaxies..

Messier 58 (M58, NGC 4579) is one of the four barred spiral galaxies in Messier's catalog (the others are M91, M95,and M109), although it is sometimes classified as intermediate between normal and barred spirals (e.g., in R. Brent Tully's Nearby Galaxies Catalog).It is one of the brightest galaxies in the Virgo cluster Spiral galaxies look like giant pinwheels. The arms of the pinwheel are made up of stars and lots of gas and dust. Gas and dust are some of the main ingredients needed to form new stars. Young stars burn much hotter than older stars, so spiral galaxies are often some of the brightest in the universe. About 20% of all galaxies are spirals

The Sombrero is a spiral galaxy, and its unusual hat-like shape is suggested by our perspective on its position in space, viewed edge-on from Earth. This creates the illusion of a hat's brim. What is an elliptical galaxy? Elliptical galaxies are shaped like ellipses (stretched circles). They are divided into eight types: E0-E7 depending on how elliptical they are. E0 ellipticals are nearly circular, while E7s are very stretched out. Elliptical galaxies are made up of mostly old stars, and do not have much gas and dust The Milky Way galaxy is the spiral galaxy we call home, as do roughly 100 billion other stars. It looks very much like other spiral galaxies when viewed from above. There are spiral arms and a bright central part.

An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.. Collectively they are thought to make up about a quarter of all galaxies Spiral galaxies contain both old and young stars, as well as interstellar matter, and have typical masses in the range of 10 9 to 10 12 M Sun. Our own Galaxy is a large spiral. Ellipticals are spheroidal or slightly elongated systems that consist almost entirely of old stars, with very little interstellar matter An elliptical galaxy, full of dark lanes of gas, likely formed in the merger of two other galaxies. Elliptical galaxies host less (or no) star birth than spiral galaxies like the Milky Way
