Taking 12 years to launch, South Korean rocket succeeds; why is the so-called developed world struggling to launch?
Who would have thought that South Korea would have to go to such lengths to build and develop launch vehicles? Compared to China, South Korea is lagging in space technology. China's Shenzhou 13 and Shenzhou 14 were launched one after another, and China has gradually matured beyond most countries in the construction of space stations.

Less than 100 km in diameter! Micro black hole found outside the Milky Way, surprisingly revolving around a star
We have the impression that a black hole is the most mysterious and massive object in the vastness of the universe. It has a powerful attraction that does not even spare the light around it. All are sucked in and do not reflect any visible light to the outside world, so the black hole is invisible to the naked eye.

What does the successive discovery of 'traces' of alien life mean? Does extraterrestrial life really exist?
Before technology was advanced, people began to discuss and fantasise about life beyond Earth. Among the many ancient ruins, there is more or less something to explore, such as the mysterious-looking murals on the stone walls. Some look like present-day aircraft, others even like astronauts, giving the impression that civilisations of the time had reached the level of extraterrestrial civilisations. Do extraterrestrial civilisations exist or not?

Researchers: New material in Antarctic snowfall that shouldn't have come anyway!
Antarctica is an area where few people have set foot and are the only remaining piece of clean land on earth. It is also the cleanest place because it is free from man-made pollution. Although much of the Antarctic is scarred by the loss of ice and the exposure of land as a result of global warming trends, these are 'harmless'. But recently, researchers have discovered a new substance in Antarctica's snowfall that is not supposed to be there.

Self-inflicted consequences? Russian cosmonauts may refuse to be fitted with robotic arms after European Space Agency 'breaks' contract
Today, the survival of the International Space Station has become an issue that needs to be discussed by all. Since a few years ago, the conflicts on the ISS have not stopped. Friction in international relations has led to the astronauts on board the ISS becoming strange. The escalation of conflicts naturally also leads to pushback and suspension of space missions. For example, Russian cosmonauts may refuse to install a robotic arm for the ISS.

Scientists discover 'Earth's Opa', 11 days are a year, life may exist
I am sure that many people have pondered this question: Is there alien life in the distant universe? To answer this question, we must first think in terms of our experience on Earth. Under normal circumstances, life can evolve as long as there is a suitable environment for survival, such as temperature, air, water, nutrients, etc., the possibility of life evolving increases infinitely when the time and place are fulfilled.

Unexplained! What is this mysterious band of light that appears over Canada at night?
The world is never short of mysterious and interesting phenomena. When there is no way to explain them, people record them, constantly deduce, hypothesize and study them. When there is no way to explain them, that part of the mysterious phenomena becomes a mystery. Technology is still at a rapid stage of development and it is impossible to explain all phenomena, so there are still many mysteries.
