Fermi Bubbles
There are two mysterious bubbles of gamma rays in our galaxy.They have a huge amount of energy in case they pass close to our world and explode they can cause the destruction of the earth. Fermi Bubbles looks beautiful in our space but they are really danger.
In 2010, astronomers announced the discovery of two vast- and very mysterious-bubbles of gamma-ray. these structures are enormous balloons of energetic gamma rays emanating from the center of our galaxy they are Two towering bubbles that stretch tens of thousands of light above and below our galaxy. The new portain,described in a paper that has been accepted for on analysis like two 30,000 light year tall incandescent bulbs screwed into the center of the galaxy, the source of these bubbles are mysterious as ever.

This is the first result in a survey of 20 faraway quasars whose light passes through gas inside or just outside the Fermi Bubbles like a needle piercing a ballong.An analysis of the full spectrum of the light sample will yield the amount of mass being edjected.The astronomers compare the outflow mass with the velocities at various locations in the bubbles to determinate the amount of energy needed to drive the outburst and possibly the origing of the explosive event.One possible cause for the outflow is a start-making frenzy near the galactic center that produces supernovas which blow out gas The bubble lookS like a giant number “8” at the center of our galaxy.From the beginning astronomers assumed these huge outflow features were cause by some major disruption from our galaxy score.They also identified high-energy jets.The Fermi Bubbles would span more than half of visible

The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
Cosmic rays are high energy charged particles, originating in outer space, that travel at nearly the speed of light and strike the Earth from all directions. The term "cosmic rays" usually refers to galactic cosmic rays, which originate in sources outside the solar system, distributed throughout our Milky Way galaxy. However, this term has also come to include other classes of energetic particles in space, including nuclei and electrons accelerated in association with energetic events on the Sun (called solar energetic particles), and particles accelerated in interplanetary space.

In 1950, a man, Enrico Fermi, during a lunch break conversation he causally asked his co-workers an interesting question, “where is everybody”. (Howell, 2014) By which he meant, since there are over a million planets which are proficient enough to support life and possibly some sort of intelligent species, so how come no one has visited earth? This became known as The Fermi Paradox, which came from his surname and two Greek words, para meaning contrary and Doxa meaning opinion, about a 100 years ago. (Webb 2002) A paradox arises when you set undisputable evidence and then a certain conclusion contradicts the idea. For example, Fermi realized that extra-terrestrials have had a large amount of time to appear
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.

Over a 1950 summer lunch at the Los Alamos National Laboratory, the great physicist Enrico Fermi asked his colleagues an unexpected question – “Don’t you ever wonder where everybody is?” Laughter went around the table as everyone immediately knew that he was talking about extraterrestrial intelligence [1]. If life arises fairly commonly, as Fermi believed, it follows that there should be advanced civilizations with the desire to visit and colonize Earth close enough to do so. However, there is no incontrovertible evidence of aliens on Earth, either now or in the past. This is called the Fermi Paradox. The lack of observational evidence for extraterrestrial intelligence is known as the ‘Great Silence.’[13]

A star begins as nothing more than a very light distribution of interstellar gases and dust particles over a distance of a few dozen lightyears. Although there is extremely low pressure existing between stars, this distribution of gas exists instead of a true vacuum. If the density of gas becomes larger than .1 particles per cubic centimeter, the interstellar gas grows unstable. Any small deviation in density, and because it is impossible to have a perfectly even distribution in these clouds this is something that will naturally occur, and the area begins to contract. This happens because between about .1 and 1 particles per cubic centimeter, pressure gains an inverse relationship with density. This causes internal pressure to decrease with increasing density, which because of the higher external pressure, causes the density to continue to increase. This causes the gas in the interstellar medium to spontaneously collect into denser clouds. The denser clouds will contain molecular hydrogen (H2) and interstellar dust particles including carbon compounds, silicates, and small impure ice crystals. Also, within these clouds, there are 2 types of zones. There are H I zones, which contain neutral hydrogen and often have a temperature around 100 Kelvin (K), and there are H II zones, which contain ionized hydrogen and have a temperature around 10,000 K. The ionized hydrogen absorbs ultraviolet light from it’s environment and retransmits it as visible and infrared light. These clouds, visible to the human eye, have been named nebulae. The density in these nebulae is usually about 10 atoms per cubic centimeter. In brighter nebulae, there exists densities of up to several thousand atoms per cubic centimete...

By 1936, astronomers had realized that the hazy balls they sometimes saw in their telescopes, which looked like stars obscured by gas, were actually galaxies (Hibbison).
Space experts are still not totally beyond any doubt how different universes have or are framed, and took the numerous shapes that we see today. Despite the fact that they do have a few thoughts regarding the sources and advancement of these cosmic systems. There is a verbal confrontation between two particular speculations clarifying the development of systems. The first is that soon after the enormous detonation around 14 billion years prior, giving way gas and tidy mists may have lead to the development of systems. The second hypothesis, which has picked up quality as of late, says the youthful universe contained some little "irregularities" of matter, which bunched together to frame cosmic systems or that connections between worlds, particularly crashes between systems, assume a vital part in their advancement. Hubble Space Telescope has shot numerous such irregularities, which may be the forerunners to cutting edge systems. As indicated by this hypothesis, the greater part of the early extensive worlds were spirals. Be that as it may, after some time, numerous spirals converged to frame
“Sheltered as we are by Earth's atmosphere and magnetic field, which deflect lethal radiation from space, we are like coddled children who have never ventured into a tough neighborhood” (Folger 2). Humans have been fascinated with space since the beginning of our time. Just like children and rough neighborhoods, we have tackled obstacle over obstacle to make it home again. In the end, we have a better knowledge and strength than before. The future of space exploration can assist us in answering the everlasting question of how the universe came to be. The more we explore the infinite galaxies, the more we can scientifically discover and create new technologies as science advances. As we continue to discover, we can create new fields and occupations for aspiring young students like myself.
Astronomers believe that most galaxies consist of a supermassive black hole at the center, which attracts all constituents of galaxies such as, dust, gases (mainly Hydrogen and Helium), atoms, stars, interstellar clouds and planets to the center by force of gravity, but are not sure whether all galaxies contain a black hole in the center. Galaxies keep moving in relative motion to one another and intermittently can come so close that the force of gravitational attraction between the galaxies may become strong enough to cause a change in the shape of the galaxies, while in exceptional cases, the galaxies may collide. If two galaxies collide, they may pass right through without any effect or may merge, forming strands of stars, extending beyond 100,000 light years in space (World Book Online Reference Centre, 2005). Hence, neighboring and often other colliding galaxies induce the sha...
