Messier 44 ( M4 or NGC 2632)
This object is best viewed with big binoculars or rich field telescopes. It’s diameter is about 1.5 degrees, so a minimum field of view of three to four degrees will allow it to stand out nicely from it’s surroundings. Personally I think an 11 or 12 [...]

The Hubble Tuning Fork
In the early 1900s, Edwin Hubble looked at galaxies like the ones you saw in the last few pages. Hubble classified the galaxies using a “tuning fork” system. The elliptical galaxies made up the fork’s handle, and spiral galaxies and barred spiral galaxies make the fork’s prongs. So his [...]

Irregular Galaxy
Most galaxies fit one of the three previously described types, but about 3% of the galaxies we observe are very different.
These so-called “irregular galaxies” do not have a lot of common features. Many of them are the results of galaxy collisions or near misses. One type of irregular galaxy is called [...]

Elliptical Galaxy (Above:- Messier 32 / NGC 221)
Elliptical galaxies are also named because of their shapes. Elliptical galaxies range from circular (remember, a circle is an ellipse!) to long, narrow, and cigar-shaped.
Elliptical galaxies are denoted by the letter E. They are also given a number from 0 to 7. An E0 galaxy [...]

Barred Spiral Galaxy
Some spiral galaxies have a bright line, or bar, running through them. These are called “barred spiral galaxies.”
The image above shows a barred spiral galaxy. Galaxies without a bar are simply called “spiral galaxies.”
The arms of a spiral galaxy have lots of gas and dust, and they are often areas [...]

Spiral Galaxies
The most common type of galaxy is called a “spiral galaxy.” Not surprisingly, spiral galaxies look like spirals, with long arms winding toward a bright bulge at the center. But be careful – if you looked at a spiral galaxy from the side, you could mistake its shape for a circle, [...]

Are all galaxies shaped like the Milky Way?
No – Galaxies can also be shaped like Barred Spirals and Ellipses, other galaxies have no definite shape.
Spiral Galaxy
An example of a Spiral Galaxy, the Pinwheel Galaxy, also known as Messier 101 (M101) or NGC 5457).
Barred Spiral
A barred spiral galaxy is a spiral galaxy with a central [...]
