Finally, we have interactions. In this type of encounter, the galaxies exchange gas and dust, but don’t actually collide.Many astronomers believe that the trail of gas and dust that stretches from our Milky Way Galaxy to one nearby is the result of an interaction when the gravitational force...
Some galaxies, such as the dwarf Galaxy called Segue 2, do not have a Supermassive Black Hole but rather orbit a central gravitational point. The word galaxy comes from the French word Galaxie, which additionally comes from the Latin galaxias meaning "Milky Way". In ancient times, there ...

What galaxies have a blue shift? What is the closest spiral galaxy to Earth? What type of star is Alpha Centauri? Which galaxies have the greatest redshift? What is at the center of every planetary nebula? What do spiral and elliptical galaxies have in common?
Surrounding the galaxy for thousand and thousand of light years is space.At great distances,however,billions of other galaxies are scattered.These galaxies are of many shapes and sizes.The Milky Way Galaxy is shaped like a spiral(螺旋型)disk.Other galaxies have been found to be shaped like ...
This is the Multiverse favoured by the science fiction community in which there are similar galaxies but are different for little reasons. Level 4 - Holographic Multiverse In a Holographic Multiverse, another universe would be a perfect mirrored image of our universe down to the smallest of items...
What happens when galaxies collide? What causes asteroids to leave the asteroid belt? How do asteroids move in space? How are asteroids formed in space? Do asteroids collide in the asteroid belt? What will happen when Andromeda and the Milky Way collide?
Giuseppe Donatiello is an Italian amateur astronomer, astrophotographer, and author who is known for his discovery of six nearby dwarf galaxies and several planetary nebulas. Why does the moon have phases? The phases of the moon are a consequence of its motion around Earth in relation to the ...
calculate their natural brightness.This told us how distant they were-and many turned out to be very, very far away.So we can be sure that the spiral nebulae really are very distant galaxies, which is what some eighteenth-century astronomers guessed, but didn't have the instruments to prove...
While it's relatively straightforward to identify the shapes of planets, moons and galaxies, it's more complex to measure the shape of the universe. In fact, this question has a very counterintuitive answer, because when we think of the shape of something, we might imagine an object seen fr...
