Space Exploration

Let's Explore Space

Space is full of Mysteries and we need to explore it. It's full of celestial bodies.

It's not completely empty as it contains plasma, hydrogen and helium as well as electromagnetic radiations , magnetic fields, neutrinos, dust, and cosmic rays.

The baseline temperature of the outerspace is 2.7 kelvin (-270.45 °C). Scientists claim that 90% of the mass in most galaxies is in an unknown form called Dark Matter which interacts with other matter through gravitation but not electromagnetic forces they also claim that majority of the mass-energy in the observable universe is Dark Energy, a type of vacuum energy which is poorly understood.

Outer space does not begin at a definite altitude above the Earth's surface. The Karman Line, at an altitude of 100 km above sea level is officially used as the start of outer space in space treaties and outer space records. 

Physical exploration of humans in space began in the 20th century with the advent of high altitude balloon flights. This was followed by manned Rocket flights, and then manned Earth Orbit, first achieved by Yuri Gagarin of Soviet Union in 1961. Unmanned flights have almost explored all planets in our solar system.

As we know human are polluting the Earth but it hasn't stopped till Earth but going to Space and later can also pollute Space so we have to stand for it and take a major decision to stop this and maintain the space
