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.
What does a spiral galaxy look like and how does its structure differ from other types of galaxies?
A spiral galaxy looks like a flat, rotating disk with spiral arms extending outwards from a central bulge. Its structure differs from other types of galaxies, like elliptical or irregular galaxies, because it has a defined disk shape with spiral arms, while other galaxies may have more irregular or rounded shapes.
A galaxy with a bulge at its center and spiral arms?
This type of galaxy is categorized as a spiral galaxy. The bulge at the center contains older stars, while the spiral arms consist of younger stars and gas and dust regions where new star formation occurs. The Milky Way is an example of a galaxy with a bulge and spiral arms.
What are the spiral arms the site of?
Spiral arms are parts of galaxies - both the galaxies and their spiral arms are huge, by our everyday standards. Spiral arms basically contain most of what the galaxies contain - including stars, dust, gas.
What galaxy arms extend from a core full of black holes?
The Milky Way galaxy has several spiral arms that extend from a central core. While the core itself contains a supermassive black hole, known as Sagittarius A*, the arms do not specifically extend from the black hole but rather spiral out from the central bulge of the galaxy.
What are the unique characteristics of a spherical galaxy?
Spherical galaxies are characterized by their round shape and lack of distinct spiral arms. They contain mostly older stars and have a dense central bulge. These galaxies are often found in clusters and have a more uniform distribution of stars compared to spiral galaxies.
WHere are global clusters found?
In spiral arms of spiral galaxies
What is a galaxy that doesn't have a regular shape called?
A galaxy that lacks a regular shape is called an irregular galaxy. Irregular galaxies do not have distinct spiral arms or a central bulge like spiral or elliptical galaxies. They often have a chaotic appearance with no clear structure.
Where can the Fibonacci spiral be found in the real world?
Arms of spiral galaxies.
What is the name of the limbs in spiral galaxies?
Arms
Which types of galaxies have a clearly defined disk component?
Spiral galaxies have a clearly defined disk component characterized by spiral arms, while lenticular galaxies have a disk without prominent spiral arms. Irregular galaxies may also have a disk component, but it is usually less organized than in spiral galaxies.
You are looking through your telescope at the night sky and you see a pinwheel shaped object what do you think it is?
It is likely a spiral galaxy. Spiral galaxies are characterized by their pinwheel shape and are composed of a central bulge surrounded by spiral arms containing stars, gas, and dust. Examples of spiral galaxies include the Milky Way and the Andromeda Galaxy.
