Our milky way galaxy is around 12.8 billion years old, whereas the universe's origin age is around 13.7 billion years. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. It has Over 200 Billion Stars: As galaxies go, the Milky Way is a middleweight. Along with the other types of galaxy, the Spiral galaxy was first defined by Edwin Hubble in 1936. The arms of the pinwheel are made up of stars and lots of gas and dust. Milky Way is a part of a cluster of galaxies called the Local Group, which comprises about 40 galaxies. Fast fact #1: The Milky Way Can Be Described With a Thin and Thick Disk and a Halo. According to many leading space research websites, out of over three quarters of galaxies discovered, 80% of them are spiral galaxies. Scientists attribute The Milky Way's current spiral arm structure to it consuming a dwarf galaxy over 2 billion years ago. Our Galaxy, the Milky Way is believed to be a spiral galaxy and not an Elliptical. Although the Andromeda is extremely far, it can be seen with the naked eye. A spiral galaxy is a kind of galaxy that looks like a flat, slowly rotating disk with a bulge in the centre, and spiral patterns extending outward from the bulge. When it's not clear what group the galaxy should go in, astronomers usually call the galaxy irregular. 2. A spiral galaxy has a spiral like structure and will have well-defined arms extending outwards.
