What is the size of a spiral galaxy?

16,300 to 163,000 light years Introduction. Most of the bright galaxies near to the Milky Way are spiral galaxies. Spirals have the smallest range of masses and sizes. They can be between 10,000,000,000 and 400,000,000,000 times the mass of our Sun, and their diameters range from 16,300 to 163,000 light years.

How does the size of an impact crater compare to the size of the object that creates it?

When a photon is absorbed by an electron, it is completely destroyed. The electron instantly jumps to a new level of energy. The photon ceases to be.

One may also ask is milky way a spiral galaxy?

The Milky Way is a huge collection of stars, dust and gas. It's called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy. What is a barred spiral galaxy quizlet? A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Dark Matter. Dark matter is a kind of matter that cannot be seen with telescopes but accounts for most of the matter in the universe.

What are the two types of spiral galaxies?

Spiral galaxies appear as flat, blue-white disks of stars, gas and dust with yellowish bulges in their centers. These galaxies are divided into two groups: normal spirals and barred spirals. Regarding this, what is the nucleus of a galaxy made of? The galactic nucleus makes up a tiny component of the Galaxy; it extends roughly 400 light-years from the Milky Way's center. The nucleus is an extreme region containing a supermassive black hole (Sagittarius A*) and extremely high stellar densities (around 10 million stars).


Can an elliptical galaxy evolve into a spiral?

The comet was discovered just two months before it made its closest approach to Earth. The comet was visible to the naked eye for three months after being spotted through binoculars.

The highest and driest part of the planet is Antarctica. It's not as warm and has less surface melt. Ice mass loss can be caused by warm, deep ocean water contacting the ice sheet base. Since the beginning of the year, the sea ice extents have shown record-high and record-low levels.

You can also ask how do stars move in a spiral galaxy?

This strange behavior may be due to perturbation caused by the central bar and spiral arms of our Galaxy, forcing stars to leave their normal circular course and take an outward path. Due to gravity, the spiral arms move through the disk in the form of density waves. What object is in the nucleus of our galaxy? black hole The nucleus At the very centre of the Galaxy lies a remarkable object-a massive black hole surrounded by an accretion disk of high-temperature gas.
