What happens during a galaxy merger?

What happens during a galaxy merger?

When galaxies merge, the gasses interact with each other. As they begin to approach one another, the galaxies begin to stretch and deform, creating tails or arms. The combination of the two galaxies then forms what appears to be an elliptical galaxy as the arms begin to disappear.

When two galaxies collide what new galaxy classification is formed?

elliptical galaxy
For example, two spiral galaxies can merge and form an elliptical galaxy. Sometimes even more than two galaxies can collide with each other.

When two galaxies of equal size are involved in a collision it is called a N )?

merger
When two galaxies of equal size are involved in a collision, we call such an interaction a merger (the term applied in the business world to two equal companies that join forces).

When two galaxies collide the stars inside them are not likely to be affected because the stars are so large compared to their diameters?

When two galaxies collide, the stars inside them are not likely to be much affected, because the SPACE BETWEEN stars is so large compared to their diameters. However, the ORBITS of stars and gas can be changed, altering the appearance of the galaxies.

What is it called when galaxies merge together?

Galaxy mergers can occur when two (or more) galaxies collide. They are the most violent type of galaxy interaction. Galaxy mergers are important because the merger rate is a fundamental measurement of galaxy evolution. The merger rate also provides astronomers with clues about how galaxies bulked up over time.

What happens when two galaxies collide quizlet?

when two spiral galaxies collide they form a elliptical galaxy. a spiral galaxy alone is neat and orderly, when two orderly galaxies collide they form a messy tangled galaxy which is an elliptical galaxy.

What happens when two spiral galaxies merge?

A: When two spiral galaxies collide, gravity is the main force that comes into play. As the galaxies approach each other, gravitational forces start to pull the stars, gas, and dust of the spiral arms out of their original orbits. During the merger, the stars become scattered and their orbits become random.

When galaxies merge do stars collide?

Although stars don’t collide when two galaxies merge, the much larger gas clouds do. The clouds in the two galaxies slam into each other violently. Shock waves from the collision run through the clouds and trigger the collapse of dark nebulae to form stars.

What holds galaxies together?

Most galaxies are not alone in the vast expanse of space, but are connected to one or more other galaxies by gravity. The same force that holds you onto the Earth can keep many individual galaxies bound together.

What happens to the planets in a galaxy when the galaxy collides with another galaxy?

Over large periods of time, the two galaxies will gravitationally interact, attracted to each other. As they merge, the stars and planets of one get mixed with the stars and planets of the other, resulting in a larger galaxy with a different structure to either of the originals.

What usually happens when two spiral galaxies collide?

What causes galaxies to merge?

Galaxy mergers can occur when two (or more) galaxies collide. They are the most violent type of galaxy interaction. The gravitational interactions between galaxies and the friction between the gas and dust have major effects on the galaxies involved.

How do you classify galaxies that have merged?

Galaxy mergers can be classified into distinct groups due to the properties of the merging galaxies, such as their number, their comparative size and their gas richness. Mergers can be categorized by the number of galaxies engaged in the process: Two interacting galaxies merge. Three or more galaxies merge.

What are some of the largest galaxy mergers ever observed?

One of the largest galaxy mergers ever observed consisted of four elliptical galaxies in the cluster CL0958+4702. It may form one of the largest galaxies in the Universe. Galaxy mergers can be classified into distinct groups due to the properties of the merging galaxies, such as their number, their comparative size and their gas richness.

What happens when two or more galaxies collide?

Galaxy mergers can occur when two (or more) galaxies collide. They are the most violent type of galaxy interaction.

Are two galaxies merging in the constellation Hercules?

Hubble Views Two Galaxies Merging. This image, taken with the Wide Field Planetary Camera 2 on board the NASA/ESA Hubble Space Telescope, shows the galaxy NGC 6052, located around 230 million light-years away in the constellation of Hercules. It would be reasonable to think of this as a single abnormal galaxy,…
