What Is Believed To Be The Origin Of Giant Elliptical Galaxies? Giant elliptical galaxies are generally thought to be the result of galaxy mergers. Ordinary elliptical galaxies may also form in this manner, or may have formed from the gravitational collapse of an interstellar gas cloud. What are 3 facts about elliptical galaxies? The largest
How Do You Describe An Irregular Galaxy? Irregular galaxies have no particular shape. They are among the smallest galaxies and are full of gas and dust. Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. … They are two small galaxies which orbit
What Are The Spiral Arms Of The Milky Way? The Milky way is a giant spiral galaxy, which has a central bulge surrounded by coiling arms containing stars, gas and dust. Our home galaxy has four known spiral arms — two major arms named Scutum-Centaurus and Perseus, and two minor arms squished between them named
Do Irregular Galaxies Have A Halo? Do irregular galaxies have a halo? They have a bulge and halo, like spiral galaxies, but don’t have the flat disk of stars. The stars in ellipticals tend to be older. Irregular galaxies have no identifiable shape or structure to them. They are often chaotic in appearance, without a
Do Galaxies Spin Clockwise? Do galaxies spin clockwise? About half of all spiral galaxies appear to be rotating clockwise and the other half counterclockwise. The direction a galaxy rotates depends on your perspective. As an analogy, consider a spinning bicycle wheel. When you look at a spinning wheel from one side, it looks like it’s
Do Elliptical Galaxies Form Stars? Do elliptical galaxies form stars? Very little star formation is thought to occur in elliptical galaxies, because of their lack of gas compared to spiral or irregular galaxies. Why do elliptical galaxies not form stars? Whilst spiral galaxies have rich reservoirs of the dust and gas that fuel star formation,
