Question

all types of galaxies far and close with clear pictures

Answer 1

Answer: There are four main categories of galaxies : Spiral Galaxy (ii) Barred Spiral Galaxy (iii) Elliptical Galaxy (iv) Irregular Galaxy Spiral Galaxy : Spiral galaxies are characterized by a distinct flattened spiral disk with a bright center called the nucleus. Our own Milky Way is a spiral galaxy : Spiral galaxies are represented by the letter s and are divided into four subgroups. These are so, sa, Sb and Sciso galaxies have a no spiral arms. Sa have spiral arms that are wound tightly around the nucleus while the arms of sc galaxies wound much more loosely. bright nucleus but have galaxies are CS

Barred Spiral Galaxy :- A barved spiral galaxy is very similar to a spiral with one important difference. The arms spiral out from a Straight bar of stars instead Of from the center. About one third of all spiral galaxies are barved. Spiral in shape. Barved spiral galaxies are represented by the letters SB and are arranges into three subgroups according to the openness Of the arms. 2 . Elliptical Galaxy: Elliptical galaxies vary in shape from completely round to extremely elongated ovals. Unlike spiral galaxies, they have no bright nucleus at their center Elliptical galaxies are represented by the letter E and are divided into seven subgroups according to their shape. These subgroups labeled Eo to E7. Eo galaxies nearly circular in Sare CS Scanned with Comicane

are extremely elongated or Shape while E7 galaxies Stretched out. Irregular Galaxy: A fourth type of galaxy. is known as the irregular galaxy. These galaxies have no discernible Shabe or structure. Irregular galaxies are divided into two classes, lm and lo. I'm class galaxies are the most common and show just a hint of structure · Sometimes the faint remnants of spiral galaxies are completly chaotic in Form . The large and small Magellanic clouds are examples of Im class irregular galaxies. αγης can be seen. 10 class M CS Scanned with CamScannel

There are four main categories of galaxies:

(i) Spiral Galaxy

(ii) Barred Spiral Galaxy

(iii) Elliptical Galaxy

(iv) Irregular Galaxy
