How many arms are there in the milky way spiral galaxy?
five
How does the Andromeda galaxy compare with the milky way galaxy?
They are both spiral galaxies, except the Milky Way is a barred spiral and the Andromeda is a typical spiral galaxy. The Andromeda has at least twice as many stars as the Milky Way, and it has more mass. The galaxies are going to merge in 4 billion years, and now they are about 2 million light years apart.
How many barred spiral galaxies there?
It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.
How many percent the spiral galaxy?
how maby percent is the spiral galaxy? {75%}
What are the four galaxies?
The 4 types of galaxies are spiral, barred spiral,elliptical and irregular. 1. Spiral galaxy is easiest to identify due to its spiral structure and has its dust and gas scattered out evenly. Two good examples are the Milky Way Galaxy and Andromeda Galaxy. 2. Barred Spiral looks somewhat like a spiral galaxy, but in the first stages. Rather than having the same look as the spiral galaxy, the gas and dust in a barred galaxy are compressed near the center, with unevenness of the gas and dust, even though it still forms somewhat of a spiral. 3. Elliptical Galaxies are one of the largest galaxies with billions of solar systems clustered to appear as one star. With dust and gas scattered throughout, these galaxies appear to be a round shape and tend to hardly contain interstellar matter. 4. Irregular galaxy is also easy to identify because it is poorly structured and are even sometimes called dwarf irregular galaxies.
The Milky Way galaxy is shaped like?
The Milky Way was long thought to be a "spiral" galaxy much like the Andromeda Galaxy . But recent observations indicate that the Milky Way is probably a "barred spiral" galaxy. Viewing the Milky Way from within as we do, it is somewhat difficult to get a clear picture.
What are four general shapes of galaxies?
Galaxies have different shapes because of what happens throughout their lives. Any galaxy, at one point or another, will encounter another or many galaxies. When encounters occur, gravity takes over. The larger of the two galaxies will consume the smaller one, this is called galactic cannibalism. The act of absorbing another galaxy will change the size of the galaxy it's shape and even the speed of its rotation. Our own galaxy, The Milky Way, is as large it is (100000-150000 Light years across.) because of galactic cannibalism. The Milky Way is as we speak consuming two other small galaxy. And in about 2 billion years, our nearest nieghbor, the Andromeda Galaxy, will collide with our galaxy. Both the Milky Way and Adromeda galaxy are spiral galaxies, but after they collide the resulting new galaxy will an elliptical galaxy, which looks like a bright white sphere.
The milky is an example of what?
Assuming that you are referring to the Milky Way, it is an example of a galaxy - and it happens to be the galaxy that we live in. Galaxies come in many shapes and sizes, but the Milky way is believed to a be a barred-spiral galaxy and has a supermassive black hole at it's core. It is also the only galaxy that is known to harbour life!!!
How many types of spiral galaxies are there?
Yes. There are two types of spiral galaxies: "S" (normal spiral) and the less common "SB" (barred spiral, with an elongated center).
How many years will we get a message from the COSMOS 1161898 galaxy?
Since COSMOS 1161898 is a barred spiral galaxy 5300 million light years from us, it will take 5300 million years for the message to reach its intended designation (and an additional 5300 million years for any reply from an alien civilization).
How many years will we get a message from the PGC 165514 galaxy?
Since PGC 165514 is a barred spiral galaxy 700 million light years from us, it will take 700 million years for the message to reach its intended designation (and an additional 700 million years for any reply from an alien civilization).
What is the shape of a Spiral Galaxy?
Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.See related link for a pictorial representation.
