Fermi Bubbles

One of the great things about the scientific study of the universe is that many times we do not know what we are discovering. There are plenty of things that we can observe without understanding, and we certainly cannot predict their future importance in understanding the universe we live in. Fermi bubbles are one of those fantastic things that we find in our universe that inspire curiosity and further study. Since their discovery in 2010, by a team from the Harvard-Smithsonian Center for Astrophysics, there has been a strong desire to understand their origin.

The first question that many may have is, “What is a Fermi Bubble?”. Fermi Bubbles are a pair of balloon shaped structures in the middle of the Milky Way that are made up of energetic gamma rays, which are the most powerful rays in the universe. They were first observed using the Fermi Gamma-Ray Space Telescope, …

The Great Void

How real is Laura Mersini-Houghton a physics professor from University of North Carolina theory about the Great Void?

Speaking of distance in the form of light years is often times hard for the average person to wrap their minds around. A light year, however, is a measure of distance, and it represents how far light can travel in one year. The velocity of light is approximately 300,000 kilometers each second! That is a staggering number, but that being said, in one year, light can travel about 10 trillion kilometers. Kilometers are an adequate measure of what goes on here on earth, but they fast become near useless when we are confronted with explaining the vastness of the galaxy. For this reason, light year becomes a useful measure when the numbers become just too big to write. For example, the distance to the next big galaxy, Andromeda, is 21 quintillion kilometers. …

The Milky Way´s hot cover

The Milky Way is a system of gravitationally bounded stars, white dwarfs, neutrons stars, black holes, interstellar gas, dust and dark matter in our solar system.

From Earth Milky Way appears as a band of light 30 degrees wide arching across the sky because it’s disk-shaped structure.

In 1610, Galileo was the first one who discovered that the band of light has individual stars. Until 1920, astronomers thought that all the stars in the universe are contained in the Milky Way, but after a lot of debates, astronomer Edwin Hubble showed that the Milky Way is just one of the many Galaxies from the 200 billion galaxies in the Universe.

The Milky Way is a galaxy in shape of a spiral with the central bar-shaped that is a diameter between 100.000 to 180.000 light years ( 1 light year is about 6 trillion miles)

The disc is shaped as a …
