What is a major difference between elliptical galaxies and spiral galaxies?
Eliptical galaxies have older stars than spirals and elipticals are oval-shaped.
What is the difference between the Milky Way and an Irregular Galaxy?
The Milky Way is a spiral galaxy with a defined shape and structure, while irregular galaxies lack a symmetrical shape or structure. Irregular galaxies may have no distinct pattern, such as arms or a central bulge, unlike the Milky Way. Irregular galaxies also tend to have higher rates of star formation compared to spiral galaxies like the Milky Way.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Are lenticular galaxies lens-shaped?
Yes, lenticular galaxies are lens-shaped. They will not have spiral arms.
How are galaxies classified based on their characteristics?
Galaxies are classified based on their shape, size, and structure. The main types of galaxies are spiral, elliptical, and irregular. Spiral galaxies have arms that spiral out from a central core, while elliptical galaxies are more rounded in shape. Irregular galaxies do not have a distinct shape. Additionally, galaxies can be classified based on their activity, such as active or passive galaxies.
What are the different names of galaxies in the universe?
Galaxies in the universe have different names based on their shape and structure. Some common types of galaxies include spiral galaxies, elliptical galaxies, and irregular galaxies. Each type has its own unique characteristics and features.
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.
What is the most common type of galaxy in the universe is?
All galaxies appear to be unique; they are all equally uncommon. Except ours; the Milky Way is the only galaxy to have US in it. Edit : Galaxies are classified into various types. The most uncommon type is known as "Irregular".
How are galaxies classified based on their characteristics and properties?
Galaxies are classified based on their shape, size, and brightness. The main types of galaxies are spiral, elliptical, and irregular. Spiral galaxies have arms that spiral out from a central nucleus, while elliptical galaxies are more rounded in shape. Irregular galaxies do not have a distinct shape. Galaxies can also be classified based on their size and brightness, with larger and brighter galaxies being categorized differently than smaller and dimmer ones.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
What is the difference between star burst galaxies and a regular galaxies?
a dinamiter of 800,00
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.
