Measurement and uncertainties are enormous issues for astronomers.I was surprised when I knew how do astronomers measured the distancs of heavenly bodies.How about our wondertful neighbour galaxy Andromeda galaxy?How far away the star when we see the most distant star with our naked eye?How large is the Universe?
Milky way galaxy
These are some of the questions.But you will be astonished by the measurement process ,measuring tools and techniques and the story behind it.In such case uncertainties play a major role.Until the end of the nineteenth century,astronomers used to measure something tha ..read more

sn’t it very peculiar!Yes it is.When I came to know this I could not believe this at all. After reading the actual reason behind it I was surprised.
The reason behind this is that when we are standing up,the attraction or tug of gravity compresses the soft tissue between the vertebrae of our spines,and when we’re lying down our tissues become slightly greater than when we are lying down. We feel relaxed when we are lying down but we generally don’t think the reason behind it. Even the scientist of NASA couldn’t anticipate this effect during their first space missions.The astronauts compla ..read more
