Can it rain with stars?

Although there may be very little real rain, some photography tricks can instead make the stars appear to rain onto the surrounding mountains, as seen in this image taken on 21 May 2013 by Diana Juncher, a PhD student in astronomy at the Niels Bohr Institute, Denmark.

Who is the father of astronomy?

Galileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the “father of modern astronomy” and the “father of modern physics”.

When did humans start studying space?

Neil Armstrong and Buzz Aldrin completed that mission in 1969. We human beings have been venturing into space since October 4, 1957, when the Union of Soviet Socialist Republics (U.S.S.R.) launched Sputnik, the first artificial satellite to orbit Earth.
