Interesting Facts About Galaxy: The Largest Creation Of Universe

Universe is an extraordinary place, full of mystery and wonder. To think, our understanding of the Universe would not even register on a scale is crazy to imagine.
While many scientists, astronomers, physicists, mathematicians, and more work to broaden and increase our grasp of the Universe, we start small and try to work our way out.
One of the liveliest and most interesting debates amongst the astrophysicists relates to the formation of galaxies. At the heart of the widely accepted theory of the galaxy formation is a dark, invisible matter that’s much more plenty in the Universe than the ordinary matter.
It’s believed that in the colder, denser regions of the early Universe dark matter and gas started to clump together, increasing in size gradually, forming the galaxies seeds known as protogalaxies.
In these protogalactic clouds, star-forming areas began to emerge, developing massive high mass stars.
These stars didn’t exist for long and gave birth to more stars from their supernova explosions. Due to gravitational effects, these protogalaxies finally collided and merged forming massive galaxies which populate the universe today.
A galaxy refers to an extensive collection of dust, gas, and stars held together by gravity. Many galaxies contain more than a trillion stars. There are hundreds of billions of galaxies in the universe. Galaxies are classified depending on their shape. The three types of galaxy are spiral, elliptical and irregular.
Examples of the galaxies range from dwarfs that consists of more than 10 million stars to the giants with a hundred trillion stars or even more. Each star orbits through their galaxy.
That is why galaxies are the biggest creations within the Universe and some of the beautiful objects in nature. As astronomers and scientists search the skies for the answers, they continue to stumble upon more galaxies that help to advance their scientific data and research.
These massive objects; home to black holes, nebulae, solar systems, planets, stars, moons, asteroids, comets, and much more are entirely different and each worth studying. Today, we will provide is a unique collection of ten most interesting and fun facts about galaxies.
1. Milky Way Galaxy is part of the “Local Group” of the galaxies in which the galaxies move relative to one another. The Andromeda Galaxy is the biggest galaxy of the Local Group, followed by Milky Way and the Triangulum Galaxy; there are about 30 other small galaxies in the group.
2. Galaxies usually collide with each other. Often, the stars within each galaxy will move past one another because of the large space between them. Any dust and gas clouds will interact, forming new stars. Gravity can also pull the galaxies into new shapes whereby two spiral galaxies might join to form a new elliptical, others produce rings, bars, or tails.
3. Starburst is a name for the galaxies which form several new stars at a quick rate, often after much molecular cloud is developed as the two galaxies merge.
4. Spiral galaxies are thought to be younger than the elliptical galaxies. As the spiral galaxies burn through the slow formation of their dust and gas star, spiral shape disappears and gradually evolve into elliptical galaxies.
5. In 2013, the Swedish and South African scientists found out that dung beetles usually navigate using the Milky Way for orientation. They’re the first creatures proven to use our galaxy for navigation.
6. Scientists have named a galaxy, “Death Star Galaxy” since it’s shooting an energetic blast from its supermassive black hole at its companion galaxy and thereby damaging it.
7. There is an unidentified object in a nearby galaxy m82 which started sending out some radio waves. The emission does not look like anything seen before and those signals were sent back when the ancestors of humanity were still swinging in the trees (ten million light years away).
8. 18th-century philosopher Immanuel Kant was one of the first individuals to theorize that the Milky Way wasn’t the only galaxy in the universe. Kant came up with the term island universe to describe a galaxy.
