The idea of building a large space telescope had been brought up back in the 1940’s. A paper was published in 1946 at Yale’s University on the advantages of astronomy from space and introduced the idea of large space telescope. It’s to be noted that his idea came up 11 years before the launch of the first ever satellite sputnik 1. However, the first meeting for setting up such a telescope was held in 1974 on behalf of NASA.

As the Telescope  be placed in space, astronauts had to be trained for fixing any issues and in 1979 NASA started its training procedures. The large telescope was named HUBBLE in honor of the astronomer Edwin Hubble,who proved that there were other galaxies in our universe and that they are moving away...

  Most of you have heard this dialogue from  the famous movie Spiderman 2. Well, guess what we have completed it. The Kstar project(Korean star) has sustained the fusion reaction for 20 seconds.You guys might feel its really small duration but the effort to achieve this took decades of hardwork. KSTAR Reactor pic credits: indiantimes Lot of countries have been into making of an artificial sun due to the increase in demand of the energy and the pollution of earth. Nuclear fusion paves the way to solve these problems. For over  a decade scientists have been working for making it a realization. Two years ago the same was achieved by china for 8 seconds. So, actually what happens in the artificial sun?   In our sun, the source of energy is fusion reaction combining lighter atoms to make a heavier atoms. In Sun hydrogen combine to form helium. For this reaction to take place, The isotopes of hydrogen(deuterium and tritium) is heated to extreme temperatures to change...
