Into the book
It's a romantic, poetic, and astonishing thought that the atoms that make up all life on Earth came from space, and that we evolved looking up at the starlight that helped create other planets and, by extension, life itself.
Our curiosity and love for the stars is deeply engraved in our genes.
The universe and our DNA are connected.
This is because all life on Earth, including us, is made up of elements that were created during the Big Bang, the moment when the vast universe was formed, and when stars collided, were created, and were destroyed.
In other words, we are all beings from the stars, children of the stars.
--- p.15 "Introduction"
Some scholars believe that Venus had a relatively stable environment during its early stages of formation, with a warm and humid climate.
However, Venus changed over time and became a barren land.
The most likely theory is that Venus heated up as the Sun began radiating heat energy.
The oceans of Venus boiled and all the water vapor evaporated into space.
From this time on, only the carbon dioxide atmosphere and sulfuric acid clouds remained, obscuring the surface of Venus.
--- p.55 "Earth's Twinkling Twin: Carbon Dioxide-Filled Venus"
Comets travel long distances along their orbits.
Some comets fly towards Earth from very far away in the solar system.
Occasionally, a comet is born when strong gravity forces push the nucleus of a comet out of its stable orbit in the Oort cloud.
These clumps of ice and dust sometimes move close to nearby Kuiper Belt objects and Neptune.
The gravity of the planets is strong enough to change the orbit or period of a comet.
Especially in the case of Jupiter and Saturn, their strong gravity often shortens the orbits of comets.
--- p.116 "A ray of light across the sky: A comet observed for a long time"
About 4.5 billion years ago, a small cloud that was part of a molecular cloud began to collapse on its own.
This cloud also contained material scattered from the destruction of other stars.
Some of these elements were created in at least one, or perhaps several, massive explosions.
As the gravity of the hydrogen molecular cloud collapsed, the sun was born.
Astronomers believe that strong stellar winds from a nearby aging star or shock waves from an explosion caused the newborn sun to spin and clump together with surrounding debris.
--- p.140 "Where Are Stars Born?: The Secret of Interstellar Clouds and Star Birth"
But how did astronomers discover the existence of dark matter, when it's invisible? The story dates back to the early 20th century.
In 1933, Swiss astrophysicist Fritz Zwicky, who was studying a galaxy cluster called Coma at the California Institute of Technology in the United States, claimed that the galaxy cluster contained invisible matter.
Because the gravity of the visible galaxies alone could not have caused the galaxy cluster to orbit so quickly.
More mass and gravitational forces, undetected, were influencing the galaxy's motion.
--- p.181 "The Most Mysterious Undiscovered Substance: The Amazing World of 'Dark Matter'"
William Herschel studied ways to safely observe sunspots, which are cooler areas than their surroundings and away from the sun's rays.
He obtained interesting results from his experiments with sunlight using a red filter.
When they shined the light through a filter into a spectroscope, they could feel the heat even though the light was invisible, and a thermometer revealed that this 'invisible' light was quite warm.
Because this light lies beyond the red end of the spectrum, it is called 'infrared'.
--- p.251 "The Herschels: A Life of Astronomy: The Lives of William, Caroline, and John Herschel"
Astrobiology, from a different perspective, is the study of 'extremophiles', microorganisms that live in extreme environments.
There are microorganisms that survive underwater volcanic eruptions and high water pressure in the deep sea.
There are also very small creatures that live in places where water is extremely scarce or temperatures are extremely cold.
There are also mysterious, simple, worm-like creatures that live deep in the ocean, buried in methane ice deposits.
The existence of life forms surviving in such extreme environments offers a glimmer of hope that life may be emerging and thriving in extreme environments elsewhere in the solar system.
--- p.304 "Unknown Territory, Astrobiology: In Search of Neighbors Who Might Exist"
You can't suddenly turn off the lights and live in the dark to observe the night sky.
If necessary, lights and streetlights should be turned on at night.
It just means that you don't have to go overboard.
Another way is to only turn on lights where necessary and turn off streetlights on deserted streets.
When you turn off unnecessary lights, you will notice new lights shining beautifully on us from far away.
It is the oldest light that has illuminated human history.
Remember, we all come from stars.
Our curiosity and love for the stars is deeply engraved in our genes.
The universe and our DNA are connected.
This is because all life on Earth, including us, is made up of elements that were created during the Big Bang, the moment when the vast universe was formed, and when stars collided, were created, and were destroyed.

Publisher's Review
“A book that is like a well-made documentary!”
★★ Orbit (Science Communicator)
“I can’t believe astronomy can be explained so easily!
“A primer for everyone who has ever looked up at the stars”
★★ Ji Woong-bae (YouTube "Space Dust's Sage Times")
13.8 billion years of time and 93 billion light-years of space,
An introductory book to astronomy that tells all this in a story.
“We are made of the remains of stars,” said Carl Sagan, author of Cosmos.
All life on Earth is composed of elements created in stars, and our bodies are also connected to the history of stars.
"Astronomy Class: Finally Encountered" explains this wondrous fact in language anyone can understand, without complex formulas.
This book goes beyond simple conceptual explanations to tell a fascinating story about why humanity has gazed into the sky and pondered the meaning of existence, and how it has asked questions of the universe and sought answers.
The author helps us feel closer to the unfamiliar discipline of astronomy, covering not only the fundamental concepts of astronomy but also the moment of the Big Bang, the birth of black holes, the evolution and death of stars, the invention of the telescope and the advancement of observational technology, and the surprising insights of astronomers who turned the academic world upside down.
The composition that delivers news from the forefront of modern space exploration is also notable.
Contemporary stories such as SpaceX, the James Webb Space Telescope, and the establishment of the Korea Aerospace Science and Technology Institute are naturally incorporated, allowing us to see not only astronomy as a space science that simply studies the night sky, but also 'what kind of future are we heading towards'.
The question posed by SF,
Science Answers
“Are we the only life in the universe?”
This question, which everyone has asked at least once, is no longer confined to the realm of imagination or fantasy.
Astronomers' exploration and research to uncover the existence of extraterrestrial life is currently at the forefront of real science.
This book follows the decades-long scientific journey toward extraterrestrial life, from the SETI project to the Drake equation, astrobiology, and the Kepler mission, with vivid examples.
It clearly shows that the age-old question in astronomy, the existence of aliens, is not just a topic of curiosity, but a realistic task that is still being seriously explored.
It also revisits familiar concepts from science fiction, such as wormholes, time travel, and the multiverse, through the language of science, and presents scientific 'standards' to answer the question, "How far is possible, and where does fantasy begin?"
Readers who enjoy science fiction will find this book a fascinating thought experiment that unfolds on the border between imagination and science.
Each question we ask now may become a topic of conversation with some intelligent life form in the distant universe in the near future.
This book will expand our imagination further and deeper through the lens of 'astronomy.'
If you look at the night sky and feel curious,
You are an astronomer
"Astronomy Class: Finally Encountered" dispels the preconception that space is a distant and difficult realm, and guides readers through the joys of observation that can be initiated simply through curiosity.
The practical part presents observation tips that you can try right away, even if you don't have a telescope.
It contains detailed instructions on how to find Venus in the daytime sky, tips for observing the rings and satellites of Jupiter and Saturn with a beginner's telescope, and an easy way to check the schedules for meteor showers, solar eclipses, and lunar eclipses that can be observed in the constellations Quadrantids, Gemini, and Perseus.
It logically explains why a telescope is a 'time machine of the universe' and intuitively impresses upon us that the more distant celestial bodies we observe, the more we can look into the distant past.
In addition, it classifies stars by color, temperature, and brightness, and helps you understand the life cycle of a star at a glance using the Hertzsprung-Russell diagram.
The explanations are brief but do not miss the key points, so even beginners to complex astronomical knowledge can learn them naturally.
This book will help readers quickly understand cosmic distances and stellar classifications, equip them with the background knowledge to enjoy the sky without equipment, and plan their seasonal stargazing trips in advance.
Above all, the book reminds us, at the beginning and end, that we are beings made of the remnants of stars, that is, 'children of stars.'
The message that the starlight that has illuminated humanity since ancient times still illuminates our lives brings new wonder to the readers' daily lives.
Tonight, look up and see the stars.
The author says:
Stars are the oldest lights that have illuminated humanity, and anyone who looks at the stars is an astronomer.
Translator's Note
Space travel without a telescope
The recent challenges of SpaceX and the launch of the Korea Aerospace Research Institute are not just news, but a signal that humanity is entering a new space age in earnest.
Space is no longer the domain of a few scientists or dreamers, but is becoming the stage of our future lives.
The more we turn our gaze to the sky, the wider the world we encounter, and the more fundamental and profound the questions we ask.
Beyond our solar system, our curiosity about the universe grows bolder with each passing year, from exoplanets and galaxies, to black holes and dark matter, to the origin and end of the universe.
"Astronomy Class: Finally Encountered" concisely and concisely covers a wide range of topics, from our solar system to black holes and the Andromeda Galaxy, deep space, and the history of astronomy to modern, cutting-edge space telescopes.
This is a friendly guide and travel book perfect for readers who are just beginning to be curious about space.
Well then, shall we go further into space with this book?
