UNIVERSE THEORIES-FROM PTOLEMY TO JAMES WEBB SPACE TELESCOPE.

Universe theories have gone through many changes and controversies. Some groups of religious people are still stuck in the theory of Ptolemy. –Ptolemy150 AD – Roman citizens lived in Egypt. He propounded the “ Geocentric” model of the universe. This means the earth is the center of the universe and all other planets are circling it. 2-Nicolus Copernicus  1543, Polish Astronomer- He propounded a heliocentric” model of the universe. This means the sun is the center of the universe and all other planets are around of it. Thus solar system came into existence. 3-Sir William Herschel  1805 was a German-born British astronomer – He established that the Universe is a Galaxy- The milky way. He found the planet Uranus and its two moons. 4-Edwin P Hubble– An American as father of the Modern cosmology.In the 1920s, Hubble made history by looking through a 100-inch telescope at Mount Wilson in Southern California Way galaxy was just one of the many galaxies in an ever-expanding universe

Our position in the universe – You are such a tiny dot in this universe, that it does not even register you, anywhere.The universe hardly cares for anybody, whether he is in agony or enjoying it;  Many mind-boggling things are happening in this universe, and You can’t stop it.                                                                                           -Millions of stars, comets, and asteroids are moving around at different speeds. Some asteroids may come and collide with our earth causing extensive damage. Or any star may burst and cause a huge black hole and send intense jets of radiation, causing the loss of millions of lives at once and rest for a few weeks or months. One such incident happened when an asteroid collided with the earth and all the dinosaurs were burned and charred. Life disappeared from this planet.

Hubble Space Telescope was the project of Edwin P Hubble, which dramatically revolutionized our knowledge about the universe. It was launched on April 24, 1990, through the Space Shuttle Discovery. Located at about 547 km above Earth’s surface, where it completes 15 orbits per day — approximately one every 95 minutes. It is still fully operational and sending unique, informational images of the universe.

JAMES WEBB SPACE TELESCOPE. Recently launched James Webb Space (the telescope is the most powerful and biggest space telescope ever launched. It’s based on the( Webb Quick Facts ) on infrared resolution, which makes the final image much larger, sharper, clearer, and vivid than its predecessor Hubble telescope. It has currently been set at its final destination point Lagrange point 2 -L2 point, which is at a distance of nearly 1.6 million km from the earth. It will explore the first galaxies that were formed very early in the universe just after the Big Bang.
