1. Describe the Milky Way. What does it contain?
The Milky Way is a barred spiral galaxy, which looks like a pinwheel. At times, people can look up to the sky and see the faint band of light, the glow of stars in the galaxy’s disk, which gave the Milky Way its name. The galaxy is of an average size, 100,000 light-years across and 1,000 light-years deep. It contains about 500 billion stars and many planets. The center of the galaxy contains a supermassive black hole, which is the cause of our galaxies spiral space. Within the galaxy, there are four main spiral arms, known as Perseus, Cygnus, Centaurus, and Sagittarius; each arm expands into smaller branches of arms. The Milky Way is contained within the Sagittarious arm in the Orion arm branch. There are also a bunch of ancient stars, globular clusters, that orbit the halo of our galaxy. Along with the billions of stars and planets, the Milky Way also contains many solar systems and smaller black holes, although scientists do not have much proof of such existences, scientists can reasonably explain their hidden presence.

How are galaxies organized and distributed within the universe?
Galaxies are organized and distributed within the universe into groups and clumps. Clumps of galaxies are called clusters, while large clumps of clusters are called superclusters. Dark matter, an undetectable energy, is what causes these clusters to form, which in turn creates galaxies. Instead of being randomly scattered throughout the universe, galaxies are organized into groups, due to the force of dark
