What are the two types of irregular galaxies?

GN-z11 is the youngest and most distant galaxy scientists have observed. This video zooms to its location, some 32 billion light-years away. GN-z11 is 13.4 billion years old and formed 400 million years after the Big Bang. Its irregular shape is typical for galaxies of that time period.

Will we ever travel to another galaxy?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Hubble recognized these two types of irregular galaxies, Irr I and Irr II.

Is spiral a galaxy?

Spiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars. Most of the galaxies that scientists have discovered so far are spiral galaxies, as opposed to the other two main categories of galaxy shapes — elliptical and irregular.

Why is the galaxy spiral shape?

Astronomers believe that galaxies have spiral arms because galaxies rotate – or spin around a central axis – and because of something called “density waves.” A spiral galaxy’s rotation, or spin, bends the waves into spirals. Stars pass through the wave as they orbit the galaxy center.
