SOLAR SYSTEM

Detailed explanation-1: -Both the Milky Way and the Andromeda galaxies belong to a subtype known as barred spirals, which make up two-thirds of the group. Barred spirals sport ribbons of stars, gas, and dust that cut across their centers.

Detailed explanation-2: -Why is the Milky Way a spiral? This is due to its rotation, or rather, the rotation of matter inside the galactic disk around the center.

Detailed explanation-3: -Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.

Detailed explanation-4: -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.
