"HORIZON: Beyond the Edge of the Visible Universe" (1/5/2019 - 31/10/2019 )

When did you look at the stars in the night sky last time?

This is a story that starts with observation of stars. By examining the light from stars, astronomers discovered the Universe is expanding, which means the Universe had a beginning in the past. The light from the most distant galaxies may provide information about the early Universe as the light was emitted very long ago. However, there is a limit in the past to which we can see. That ‘edge' of the Universe is the cosmic microwave background radiation, the ‘oldest' ‘light' that reaches the Earth. Fortunately, from the fluctuations in this radiation, astronomers can extract information to allow us to reach beyond this edge and probe into the Universe at still earlier moments. Astronomers can also figure out the ratio of ordinary matter, dark matter and dark energy in the Universe. The delicate balance of these constituents contributes to today's Universe, formation of atoms, and ultimately the possibility of the very existence of living things and human.

In this Sky Show "HORIZON: Beyond the Edge of the Visible Universe", you will follow the footsteps of various important astronomers from different generations over a hundred years to reveal the mystery of the Universe. Apart from learning the science concepts illustrated by vivid animations, you will also witness how astronomers broaden our understanding of the Universe and open up our horizon through imagination, reasoning and technology.

And everything starts from our curiosity when we look at the stars in the sky.

How can we find out how far a star is? Once we know the intrinsic brightness of a star, we can tell its distance as a star appears dimmer if it is farther away. Then how can we tell the intrinsic brightness of such remote stars? Henrietta Leavitt's discovery gave us the answer.

A revolutionary idea is always hard to be accepted even it really is the truth. This was what happened when Georges Lemaître proposed his new idea of the expanding Universe.

Edwin Hubble discovered that the farther away a distant galaxy, the faster it was receding. This is known as Hubble's law, one of the most important laws in cosmology.

Arno Penzias and Robert Wilson found that no matter how they cleaned the antenna, noise was still received. The ‘noise' was in fact evidence supporting that the Universe began in an extremely hot and violent explosion, called the Big Bang. The ‘noise' was cosmic microwave background radiation.

From the fluctuations in the cosmic microwave background radiation, Eiichiro Komatsu tried to figure out the ratio of ordinary matter, dark matter and dark energy in the Universe which relates directly to the puzzle about the existence of the Universe.

We are now at the time to reach beyond the edge of the visible Universe…

… to witness the evolution of the Universe which relates to the birth of our Sun and eventually the very existence of ourselves!
