The scope of the universe as understood by humankind has expanded with the development of astronomy.
Starting from the mythological universe of ancient times, let us explore the Ptolemy’s geocentric theory, the heliocentric theory, the revolution brought by the invention of the telescope, spectrum analysis, and the latest technologies in today’s astronomical observatories.
13.8 billion years ago, the universe began from a small dot. 380,000 years after the big bang, the density of the universe became low enough to allow light to travel freely. Hundreds of millions of years later, the first stars and galaxies began to form. smaller galaxies merge together to become larger galaxies. 4.6 billion years ago, our star, the Sun was born. Orbiting our newly-born Sun, dust and rocks collided to form larger bodies, which became planets. As the Earth formed, a Mars-sized object smashed into it. Slowly the Earth cooled, Oceans and continents emerged, and life began and evolved in various ways.
When these ancient people looked upward, at the Sun, the Moon, the myriad of stars and the Milky Way; what did they think about them? It must have been a huge mystery. To explain these natural phenomena; ancient civilizations created myths and legends.
In Ancient Egypt, people believed that the world began from the darkness of the Nile River. And it was here that the goddess of the sky, Nut, and the god of the Earth, Geb were born.
There were also attempts to scientifically understand the universe. People thought that the Sun, the Moon and stars rotated around the Earth. That the universe was eternal, unchanging. In the early 1500’s, the astronomer, Copernicus proposed that the Sun was at the center, and the Earth rotated around it. His idea shattered the old thinking.
Roughly a century later, Galileo created a telescope to observe the night sky. He discovered four moons orbiting Jupiter, and complete phases of Venus to be similar to Earth’s moon phases. This proved that Copernicus was right. Kepler invented an improved refracting telescope. Isaac Newton was the first to invent a reflecting telescope. As more people observed the sky with various telescopes , many more discoveries were made. Things that were previously invisible with the naked eye were now visible.
As more people observed the sky with telescopes, many more discoveries were made. and now to get a closer look at faint objects, larger telescope are needed.
Among the world observatories, many are located on the summit of Mauna Kea in Hawaii. The Subaru telescope has one of the largest mirrors in the world with a diameter of 8.2 meters. The Keck telescope is combined by hexagonal segmented mirrors to make a large mirror. In the Canary Islands, sits the largest single standing telescope in the world.
On the Atacama desert in Chile, there is a VLT telescope. These four 8,2 meter telescopes can be operated separately, or combined to make the largest telescope in the world. At an altitude of 5000 meters in Chilean Andes Mountains, 66 large antennas reach up to the sky, it’s ALMA.
