  Zeeshan and Advik returned back to me and enquired about my health.  They hesitated to see my parents.  They both begged pardon from my parents and Aalya.  My parents interrupted them kindly, "Please don't feel sorry.  You have apologized multiple times.  Actually, we must thank you for informing us and admitting my son to the hospital.  Whatever happened is happened, nothing is in our hands.  Today, my son is alive because of you both.  We are very thankful for you and your father". "My son told me everything about you and your brother.  He always updates us about his research.  Even though he was in a critical situation, he left a message for us.  Only my family members can understand the code language.  My father used to teach him.  It is easy and precise.  I can understand the entire situation very well."  Zeeshan praised my parents with an emotional tone, "So kind of you.  Thank you so much for n...

           In the Earth, we having thick atmosphere and so many molecules collide each other.  But in the Moon, it has thin atmosphere with small amount of molecules.  The molecules in the atmosphere, even won't collide (free flow molecules).  So, Moon having atmosphere .       ISRO launched our first mission to the moon, Chandrayaan-1 .  It was very unique one, which focus to search for evidence for water on moon , to understand the origin of the moon from minerals and chemical composition and also to detect the presence of any atomic species .  It shows the presence of water in the moon.      How it forms?      Water molecules is made up of two hydrogen atom and one oxygen atom, this is normal water(H2O).  In heavy water (D2O) a normal hydrogen atom is replaced with deuterium, which is like hydrogen except that it has extra neutron in its nucleus.       ...

The sky on the Moon is always dark(both day and night). Why?

            The sky on the Moon is always dark(both day and night). Why?       First we should know, why the sky is blue on Earth?  The daytime sky is blue because light from the nearby sun hits molecules in the Earth's atmosphere and scatters of in all directions.      The blue colour of the sky is a result of this scattering process.  At night, when that part of earth is facing away from the sun, space looks black because there is no nearby bright source of light, like the sun, to be scattered.      If you were on the Moon, which has no atmosphere (it don't have that much atmosphere to scatter), the sky would be black both night and day.
