#1 If you want to be awed by the night sky, stand outside with your eyes closed and see how your night vision develops. You’ll be surprised at how much you can see.

#2 The Sun is at the centre of our Solar System, and all other objects orbit it. This was proven by the efforts of Tycho Brahe, Johannes Kepler and Isaac Newton over the next century or so.

#3 In the late 1600s, Isaac Newton demonstrated that white light was made up of all the colours of the rainbow, and that refraction occurred through a prism, changing the direction of red light less, and changing the direction of blue light more, to reveal the rainbow.

#1

The next time you have a clear night, with no clouds spoiling the view, stand with your eyes closed for a few minutes by the door to outside. Let your night vision develop, and you won’t be disappointed by the stars.

#2

The idea that the Sun is the center of the Solar System was first supported by the Catholic Church, but was later proven by the scientific community. It would take the efforts of Tycho Brahe, Johannes Kepler, and Isaac Newton to establish this.

#3

The Sun was not made of coal, but it was still unclear what the Sun was made of. In the 1800s, physicists began to wonder if the Sun and the stars could be powered by combustion, but they realized that the Sun would burn through its coal in just 5,000 years.

#4

Fraunhofer was the first to create a spectrograph, an instrument that is the cornerstone of modern astronomy and astrophysics. He was shocked to find that the rainbow of light from the Sun contained dark lines that no one had noticed before.
