A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way. Galaxies range in size from dwarfs with just a few thousand (103) stars to giants with one hundred trillion (1014) stars, each orbiting their galaxy's own center of mass. Galaxies, are categorized according to their visual morphology, including elliptical,spiral, and irregular. Many galaxies are thought to have black holes at their active centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As of July 2015, EGSY8p7 is the oldest and most distant observed galaxy with a light travel distance of 13.2 billion light-years from Earth, and observed as it existed 570 million years after the Big Bang. Previously, as of May 2015, EGS-zs8-1 was the most distant known galaxy, estimated to have a light travel distance of 13.1 billion light-years away and to have 15% of the mass of the Milky Way.
The Milky Way is the galaxy that contains our Solar System. Its name "milky" is derived from its appearance as a dim glowing band arching across the night sky whose individual stars cannot be distinguished by the naked eye. The term "Milky Way" is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος (galaxías kýklos, "milky circle"). From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies—now estimated to number as many as 200 billion galaxies in the observable universe.
The Milky Way is a barred spiral galaxy that has a diameter usually considered to be about 100,000–120,000 light-years but may be 150,000–180,000 light-years. The Milky Way is estimated to contain 100–400 billion stars, although this number may be as high as one trillion. There are probably at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 27,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm. The stars in the inner ≈10,000 light-years form a bulge and one or more bars that radiate from the bulge. The very center is marked by an intense radio source, named Sagittarius A*, which is likely to be a supermassive black hole.
SpaceEngine (stylized as "Space Engine") is a proprietary 3D astronomy program and game engine developed by Russian astronomer and programmer Vladimir Romanyuk. Using real astronomical catalogs and procedural generation, it creates a three-dimensional planetarium representing the entire universe. Users can travel through space in any direction or speed, and forwards or backwards in time. SpaceEngine is in beta status, and is currently freeware for Microsoft Windows. It uses pseudo-random numbers to procedurally create any kind of planetary system, nebula or galaxy.
One of the main features of the program is its scientific accuracy. Cataloged objects are based on real data, while procedural objects are built around the cataloged universe using realistic generation algorithms. Properties of objects, such as temperature, mass, radius, etc., are presented to the user on the HUD and in an accessible information window. Users can observe objects from small spacecraft to galaxy clusters, similar to other simulators such as Celestia. SpaceEngine includes thousands of real objects, including stars from the Hipparcos catalog, galaxies from the NGC and IC catalogs, several well-known nebulae, and all known exoplanets and their stars.
An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see Electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings.
The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a plectrum. The string vibrates at a necessary frequency and also create many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.
Gitterns, a small plucked guitar were the first small like guitar instruments created during the Middle Ages with a round back like that of a lute. Guitar like shaped instruments were not seen until the Renaissance era where the body and size began to take a guitar like shape.

Well here I am, I'm sitting alone again
I'm staring up at the sky
Which at this lonely moment is my only friend
And suddenly as I gazed upon the night
Well I notice the stars
They began to shake and dance and burst
And fall into the darkness
They exploded down, I knew what I had to do
I ran up to the top of the hill
And I took a hold for you
You were the sweetest star that fell
And yes, I held onto it close to the numbness in my heart
And then I kissed a star, yes I did
I wrapped it up inside of a golden bow
And then I ran away just to find you
'Cause this was your gift, your gift, oh shit
A star that I kissed
Oh the galaxy that lives inside your eyes
Was in need, I said it was in need
Of a, of a brand new shining light
I said I wished to the dark sky above
That all I had was to be captured
And willingly turned over to you
I know you better now and at this I smile
I simply gave to you the symbol of what you are to me
You are the star that shines
And explodes with light and I love and embrace
Love and embrace all that I can
You better take this blindness and stay away from me
And let me bask inside of your golden seam
I never knew such simple astronomy
I never knew it could come to me and not by the ways of the heart
And call on me to be one of those strangely dressed wise men
Who follow the stars to their love
You are such a perfect star to wish upon
Well I love you and God and I'm hopeful
Of what this lonely night may lead me to
So I said god I'm hopeful
Of what this lonely, lonely night
Will lead me tonight
Oh well, well I'm hopeful that this lonely night
Well it shines so right, I'm hopeful
I'm hopeful of all good things to come about
I'm wishing upon you now, yeah, I'm wishing upon you now
Free me and let me indulge my view
Oh, most beautiful you keeper of starlight
Take on me, oh, oh, oh well here I am
I'm sitting all by myself again
I stare up at the sky
Which at this moment is my only friend
Say well, suddenly as I gazed upon the night
Well I notice the stars
They began to shake and burst
Oh, it looks like they want to fight, no
They were dancing, they were romancing
Oh, they were falling in love
They falling in love all over
Falling in love all over
Falling in love, falling in love, falling in love
I say falling in love, falling in love all over
Falling in love, is my best friend
