Our Milky Way_Know Cosmic Dance of The Sun
From Galileo to Einstein, much has been learned but much remains to be known about our Milky Way and Man's spot on that dance floor
Our Milky Way is an astonishing astronomical phenomenon that human beings have begun to understand its vastness & mysteries only recently, climbing on the shoulders of great minds of the past over the last several centuries .
Particularly, We have to return to Dutchy of Florence in modern Italy to meet a great mind named Galileo Galilei (1564-1642) who lived and worked there under difficult circumstances. But Galileo left a legacy in astronomy that still inspires us today. In fact, he was the first to observe the Milky Way with his telescope and wrote about it.
Other great minds from Isaac Newton to Albert Einstein and beyond today have been inspired by the work of Galileo Galileil. .
Modern astronomy rooted in science of physics and mathematics thus to a leap forward as the Renaissance that accelerated with Leonardo de Vinci (a generation or so earlier in the same community where the Renaissances began with the arts and then took roots in the sciences that flowered in centuries later. . .
Much is yet to be learned about the place of the life giving sun, an average start in this one Milky Way that consists of perhaps 200 billion starts. In the core of the Milky Way, there is dark matter that consists of most of the mass in this small part of the much greater vastness of the Cosmos. What is this dark matter and associated dark energy, much is yet to be learned. We do know now that the visible world with all the stars existing in the Milky Was is but a small part of the vastness of dark matter and dark energy that pervades the center of our Milky Way and other such clusters of stars, billions in number beyond this neighborhood of space.
What is Milky Way ?
This name derives from its appearance as a dim un-resolved "milky" glowing band arching across the night sky. The term "Milky Way" is a translation of the Latin for "milky road",
The concept of this faint band of light being made up of stars was proven in 1610 when Galileo Galilei used his telescope to resolve it into individual stars. In the 1920s observations by astronomer Edwin Hubble showed that the Milky Way was just one of around 200 billion galaxies in the observable universe.
The Milky Way is said to be a spiral galaxy with 100,000-120,000 light years in diameter containing 200–600 billion stars. The galaxy is estimated to contain 50 billion planets, in this vastness, is earth the only planet with life form?
This question has been asked by many thoughtful humans but so far we do not know the answer. We do know statistics favors existence of life forms in other planets in this vastness of our own Milky Way. Perhaps there are high forms of life than human beings somewhere in this vastness of the Milky Way or among other billions of galaxies that have been identified but yet to be known.
Fictional movie “Contact” created by Astronomer Carl Sagan thus makes a case for imagination for such future magic as we learn more and able to peer in to the vastness of the distance with new tools from science and technology.
That’s a discussion for another day. But now in this introduction to the Milky Way, some photos past, and present, I am glad to share and discuss as we go. .
Perhaps in the next decade or so, some experimental verification of hidden dimensions as have been hypothesized by the Super String Theory beyond the world of Theory of Relativity will be made. Perhaps some new knowledge about dark matter and dark energy will come to light. Both are possible near term as the next foreseeable scientific advancement waiting in the wings.
The startling cosmic dance of the universe has many dimensions, far beyond the comprehension of humans using modern science tools and knowledge as of today.
Mind of the Creator is nearer to us today than the era of Galileo Galileil five centuries ago.
