There are three different main shapes of galaxies that exist in our universe. The one you are probably most familiar with are spiral galaxies, like our Milky Way, which have two or more arms spiraling around a center core. Then there are the elliptical galaxies which have egg-like ...

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...
The force of gravity is enough to distort the shapes of galaxies as they encounter one another. But galaxies themselves are mostly (relatively) empty space. Stars are just tiny little dots compared to the enormous volumes of space within a galaxy. When you think of these beasts colliding, don...
Why are galaxies different shapes? What can be used to model the expanding universe? What is the name of our Universe? How did the Oort cloud get its shape? Where is the expanding universe located? What geometric shape does a moon crater resemble? What is the w-shaped constellation? What...
A Nebula is named after the Greek word for “cloud”. Nebulae (plural) come in many shapes and sizes and have a way of captivating those that observe and photograph these deep sky objects in space. Most nebulae are enormous in size. Some are even hundreds of light-years in diameter. Neb...
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 ...
star cluster shot out from M87's enormous black hole, which is 1,000 times more massive than the Milky Way's. But never fear: It's very unlikely that its trajectory will bring it close to us, and it'll probably end up just hanging out in a group of galaxies outside the Virgo ...
Over the last roughly 2 decades, the enormous amount of energy released from Active Galactic Nuclei (AGN) and their coupling with the host galaxies (AGN feedback) have become key areas of study. For reviews of AGN feedback, see (e.g., [1,2,3,4,5,6,7]). There are three phenomena...
The combination of the two disturbances (i.e. the two “virtual particles”) remains a particle with the energy, momentum and mass of the incoming electron. Now there are many other types of disturbances that fields can exhibit that are not particles. Another example, and scientifically on...
