What else can I help you with?
Collisions between galaxies is thought to?
Have no real effect on the merging "colliding" galaxies
Active galaxies are thought to be powered by?
Active Galaxies are thought to be powered by rotation
Which of the galaxies is shaped like a sphere or an egg?
you would of thought
What is tough to be at the very center of all galaxies?
Perhaps you mean "thought to be"? - It is believed that all, or most, galaxies have a supermassive black hole at their center.
How many galaxies are irregular?
Irregular galaxies are thought to represent about 25% of all the galaxies. That puts the total at around 25 billion - depending on the source for the total amount (100 -> 300 billion)
What is at the center of Seyfert galaxies?
Nothing special - Just like most large galaxies, they are thought to have a super massive black hole at the centre of the galaxy.
What are the two cloud Magellan galaxies that orbit the milky way?
They are simply known as LMC and SMC. As far as what they are made of, They are simply galaxies. hope this helped. thought it probobly didn't
Why are far distant galaxies not visibly younger and less well formed than nearer ones?
They actually are. Galaxies that are only millions of light years won't show much difference - that's too short compared to the age of galaxies. But there is definitely a trend in galaxies at distances of billions of light-years. Their metallicity is lower (i.e. they have had fewer supernovas to pollute the interstellar gas), and there is a greater percentage of disc galaxies (elliptical galaxies are thought to form by the collision of disc galaxies).
How does the galaxies move in the universe?
The general tendency is for galaxies to move away from one another - the further apart they are, the faster they move away from one another. In other words, the Universe is expanding. Galaxies also have some "random" proper movement, which can be thought of as superimposed on this general expansion.
Quasars are thought to be the center of distant?
Quasars are thought to be the centers of distant galaxies where supermassive black holes are actively accreting matter. The intense energy emitted by this process makes quasars some of the brightest objects in the universe. Studying quasars can provide valuable insights into galaxy formation and evolution.
What did many believe about galaxies prior to the 1920?
They thought that the milky way galaxy included every other object in space.
What caused the galaxies and planets to form?
Galaxies and planets are thought to have formed from the gravitational collapse of vast clouds of gas and dust in space. Within these clouds, gravity caused the material to clump together, eventually leading to the formation of galaxies composed of billions of stars and planets within these galaxies.
