How is a potentially threatening celestial body determined? What are the circumstances under which an Earth impact notification will be received?
I have to say that the whole universe works very cleverly. Seemingly random, yet so regular. Take our Earth, for example. If the Earth had been a little further or closer to the sun, almost all living things would not have been possible. And the temperature and environment would certainly not be the same as it is now. Then there is the movement between the planets, each in its own orbit, without collision. (There is my personal summary of the article's highlights at the end of the article.

It is well known that one issue that must be taken into account in the renovation of new houses is the removal of formaldehyde.

How does the return of southern weather occur? And what to do about it? Find out at a glance!
In spring, southerners are sure to experience a return to the south. Just in the past two days, this year's return to southern China has suddenly arrived. As a Cantonese native, I know the power of a return to the south. The tear marks on the walls, the ground on thin ice, the accelerated decay of food, the clothes that have not yet dried. These are the things that, as the biggest annoyance of the southerly days, fill everyone who lives in the south with boredom!

Why aren't humans covered in hair like other animals? It's because they are kept as toddlers!
Summer is the time for swimming. When you go to the pool, all kinds of swimming costumes do not wrap around your whole body. Boys, in particular, are bare-chested. It is often at such times that we notice that some people have chest hair. But even if there is, it is not dense. Compared to Westerners, not many Easterners have chest hair. Having said that, do you think it's chest hair today? Not exactly. What I want to say today is that, compared to other mammals, we humans do not have a thick coat of hair.

What are the dangers of volcanic eruptions? And what is the Year Without Summer?
The news of the volcanic eruption in Tonga has been on my radar for the past two days, closely followed. It is, after all, a catastrophe that will affect us for the rest of our lives. Every time a catastrophe of this magnitude happens, I feel deeply the insignificance and arrogance of human beings who think they have conquered nature but are unable to avert it. But often when faced with a catastrophe, we can see the difference between humans and other animals, and that is cooperation. The spirit of support from all sides in times of trouble is one of our very important human qualities.

The world's nine oldest surviving "antique" astronomical observatories
Since the birth of man on earth, man's reverence for the heavens and his search for the mysteries of heaven and earth has rarely ceased. Astronomers and artisans have also built various observatories. Even today, one cannot help but admire the subtlety of the ancients in their grasp of the planets, constellations, and seasons. The significance of astronomical observation at that time has always been a combination of politics, religion, and science, and is far from the scientific significance of today. Let's go back to that distant time and explore nine of the world's oldest astronomical observatory sites.

Do you really hate sports? These scientific advice can help you get moving.
Early humans didn't like sports. Throughout human history, in most of the time, human food resources are so scarce that they have to search everywhere for food. But once they are full, they will stop to rest and save their strength, because they do not know where the next meal will be. So, you want to sit down and watch Netflix? Instead of going to the gym, this is actually a natural tendency of human beings. This may give you some comfort when you are resting.
