How are multiple galaxies are organized?

Answer 1

Galaxies come in a number of forms and are very distant being that our own galaxy is 100,000 light years across, meaning traveling at the speed of light it takes one hundred thousand years to traverse [travel across], and then between our galaxy and others there are hundreds of thousands of light years. Generally, like stars, we use light wavelengths to determine the makeup, distance and speed of galaxies, whereas for the way they look we use varying wavelengths of energy, gamma rays, x-rays, infrared, ultraviolet and so on to get varying appearances of the distant objects and hopefully get a good idea of what they look like.

Answer 2

The four groups of galaxies are put into groups by the way they look, Spiral galaxies like our vary own milky way have tentacle like arms that make a spiral, there are also barred spiral galaxies that have only two arms in which give it a bar like appearance like the sculptor galaxy. We also have the elliptical and irregular galaxies. Elliptical galaxies have an ellipsoid or.. egg shaped look to them, Irregular galaxies don't have a particular look to them .. its and odd galaxy for sure one that always looks different from other galaxy. So i would say there classes depend on how they look.. there characteristics.

Answer 3

Galaxies are organized into clusters and superclusters. Clusters contain many galaxies that are bound together by gravity, while superclusters are even larger structures made up of multiple galaxy clusters. These structures are interconnected by filaments of gas and dark matter, creating a vast cosmic web-like structure in the universe.

Answer 4

Scientists group galaxies based on there shape. There are three categories spiral, elliptical, and irregular.

Answer 5

Multiple galaxies are organized into groups and clusters, containing anything from a few to thousands of galaxies. Larger groups are called superclusters.

Answer 6

It started by Big Bang theory.😚
