Ten interesting facts of the Milky Way Galaxy
- The galaxy has over 200 billion stars, out of which only 2500 can be seen from a single point on the sphere. The Galaxy loses stars and produces 7 stars in a year. Two majestic spiral arms bright bands of billions stars sweep out from Scutum–Centaurus Arm and Perseus Arm.
- The Milky Way Galaxy is made from other galaxies, and the current shape and size of this galaxy is achieved by consuming other small galaxies.
- The galaxy consists of a supermassive black hole at the center, which is known as Sagittarius A* that is bright, and condensed source of planetary radio waves.
- The galaxy is about 600 thousand trillion miles, and it takes nearly 100 thousand years to cross the galaxy.
- A stellar explosion that surpasses the complete galaxy, radiates energy as much as the sun and continuously keeps emitting throughout its life span is known as Supernova. The primary source of heavy elements in the universe are credited to supernova.
- All galaxies, stars, gas, dust, and planets are only seen half of 1% and everything else is obscure, called the Dark matter, which Milky Way requires, as it has mass and gravity.
- Away from the Milky Way galaxy, from the solar system are about 150 stars comprising the bipolar cluster that depict the exact age of the Milky Way galaxy.
- The Galaxy is always moving in space, where the earth revolves around the sun, and the sun revolves around the galaxy, and the galaxy moves relative to the cosmic microwave background.
- The Milky Way Galaxy is filed with gas and dust, out of which nearly 15% is visible to the naked eye, and the rest is in form of the stars.
- The galaxy is cosmically warped and the warped area is the consequence of hydrogen gas molecules extending away from the two-dimensional surface of the spiral arms.
