The Eternal journey of Voyagers into the Space

If you have seen Interstellar, chances are really high that you must have liked it. But have you ever paused and focused on the word Interstellar itself? It means travelling between two or more different star systems. Our solar system is also a star system. In Interstellar, Cooper travels through a wormhole and reaches another star system. In other words, he travelled interstellar. Yes, it was just a movie. Umm not just a movie for me personally but nvm. But here is the part that still blows my mind. Humans have actually made two real spacecraft that travelled interstellar for real. Not CGI, not fiction, not theory. Two tiny machines built by human hands have left the Sun behind and are now drifting in the emptiness between the stars. I genuinely envy them. Meet Voyager 1 and Voyager 2 The two silent explorers who left home in 1977 and never returned. NASA launched Voyager 2 first on August 20, 1977 Then launched Voyager 1 on September 5, 1977 Yes, Voyager 2 was launched e...

A Tour to Our Milky Way

Complete exploration of Milky Way

In the night all the stars that we see in the sky are part of one
galaxy known as the milky way. In the night sky it was imagined that milky way contains all the stars in the universe but with the help of advanced telescopes we get to know that milky way is just one of the galaxy among billions of galaxies.
The stars are arranged in a pinwheel pattern with four major arms, and we live in one of them, about two-thirds of the way outward from the center. 
Most of the stars in our galaxy are thought to host their own families of planets.

Quick Review about the milky way

. Confirmed Exoplanets-  4414 Planets
. Confirmed Planetary Systems- 3074 Systems

What is at the Center of the Milky Way?
All of the stars in the Milky Way orbit a supermassive black hole named Seggiterius A at the galaxy's center, which is estimated to be four million times as massive as our Sun. Fortunately, it is a safe distance from Earth, at around 28,000 light-years away. Our galaxy is one of the countless billions in the universe, each having millions, or more frequently billions, of stars of its own.
We call our galaxy the Milky Way because it appeared to ancient observers to be a milky band of light – like a cosmic roadway – stretching across the dark sky.
Black Holes
Size And Distance
It is estimated by the scientists that the milky way galaxy has a radius of 52,850 light-years. From the earth, the distance to the center is 25,650 light-years. The Milky Way zips along a galactic orbit at an average speed of about 514,000 mph (828,000 km/hr). It takes about 230 million years for our solar system to make one revolution around the galactic center.

 Location
The Milky Way's long-lost sibling | Space | EarthSky

Our Milky Way is located in a local group of more than 30 galaxies that are gravitationally bounded with each other. This local group is stretched 10 million light-years across. Among this group, the nearest galaxy to the milky way is Andromeda Galaxy which is many times larger than our milky way. Scientists have after 1 billion years these two galaxies will collide with each other making a single galaxy called milkydromeda.

Stellar Classification of Stars

-
Image
Empire of Stars It has been a long time that we are exploring the universe through modern telescopes to find other worlds where we can find other civilizations. Till now there are no accurate pieces of information we can find about the alien worlds but during these we have found about many new planets and new types of stars. In this post, we will discuss the different types of stars on the basis of stellar classification. What is Stellar Classification? It is a method to classify stars on the basis of their  spectral  characteristic.  A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity,    On the basis of this classification stars are divided into 7 parts. 1. O type Stars Color- Blue or White Temperature- More than 30000 Kelvin Stars of this type are very rare, but because they are very bright they can be seen at great distances and four of the 90 mos...

Good Day everyone!!! I'm Samuel A.Estrope lll . And today I just finished the full detail regarding about the Anniversary of First Image Of Black Hole, April 10,2019. May all of you appreciate my works in this article .You can ask me privately if you have still questions In My Facebook Account(Samuel A.Estrope lll). Enjoy reading our fellow Cosmic Explorers in this Article. Celebrating The First Anniversary Of First Image Of Black Hole in Human History   The First image of Black Hole captured in  Human History is April 10,2019.Exactly my Birthday,look at Coincidence. Black Holes are extremely dense celestial  bodies(regions in space)that have very strong gravitational force,that it can tear apart the Fabric of Space-time .The Gravitational force of a Black Hole is so strong that nothing not even light can escape.The pull of a B lack Hole's Gravity behind  its Event Horizon makes space to fall towards the Space-time singularity faster tha...
