? The Milky Way is the name of our Galaxy.
? It is a large, spiral galaxy with billions of stars (including the Sun) and the Solar System.
? About 10-15% of the Milky Way is made out of dust and gas, with the rest being stars.
? The oldest star in the Milky Way is estimated to be about 13.6 billion years old & is said to have been formed after the ‘Big Bang’.
? There is a huge black hole in the center of the Milky Way called ‘Sagittarius A’ that is responsible for the gravitational force that holds it together.
? The Milky Way is surrounded by a dark halo that is far bigger than the galaxy itself.
? Although Greek Philosophers proposed that the Milky Way is a vast collection of stars, Galileo Galilei gave actual proof through his rudimentary (basic) telescope about its existence.
? Astronomer Edwin Hubble discovered that the Spiral Nebula (a could of gas or dust in outer space) Andromeda, is actually a galaxy and that the Milky Way was just one of the many galaxies in the universe.
? Every picture you have seen is only a representation or interpretation of the Milky Way, as it would take a spaceship thousands of light-years to capture an actual picture of the entire galaxy.
