What would happen if the Andromeda Galaxy a spiral about the same size as the Milky Way galaxy collided with the Milky Way?

What would happen if the Andromeda Galaxy (a spiral about the same size as the Milky Way Galaxy) collided with the Milky Way? The two galaxies would pass through each other, the stars sailing past each other unharmed, and the interstellar gas and dust clouds would collide to produce a burst of star formation.

What would happen if the black hole in the middle of the Milky Way disappeared?

The orbits of many stars in the galaxy – which is only about 200 light-years across – are quite strongly influenced by the black hole. Removing it would certainly disrupt a number of orbits.

What happens if the Milky Way collides with another galaxy?

The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical. The pair will end up forming a binary at the heart of the new, larger galaxy.

What happens when stars collide?

Stars rarely collide, but when they do, the result depends on factors like mass and speed. When two stars merge slowly, they can create a new, brighter star called a blue straggler. Stars that collide with a black hole are ultimately consumed.

What happens to the orbital energy of stars in a galaxy?

The orbital energy of the stars is lost in the form of gravity waves, allowing them to come close to each other. Our Milky Way Galaxy is a giant spiral galaxy. For this figure, label the various, basic parts of the galaxy and indicate the total diameter of the galaxy.

What happened to the Milky Way in 4 billion years?

Second row, left: In 3.75 billion years Andromeda fills the field of view. Second row, right: In 3.85 billion years the sky is ablaze with new star formation. Third row, left: In 3.9 billion years, star formation continues. Third row, right: In 4 billion years Andromeda is tidally stretched and the Milky Way becomes warped.

What happens to a planetary nebula when its mass increases?

More massive stars burn fuel faster than low-mass stars and thus have shorter lives. A planetary nebula glows because light from the central star causes emission lines. It will collapse. the star is getting redder, the star is getting larger

How to find the distance to the center of the Milky Way?

Order the steps for finding the distance to the center of the Milky Way from variable stars in globular clusters. 1. Find the period of the variable stars 2. Use the period luminosity relation to find luminosity of the stars 3. Use the luminosity and brightness to find distance 4.
