Using the James Webb Space Telescope (JWST), astronomers at the Institute for Astrophysics in Paris have discovered what may be the oldest four galaxies in the known universe, located just over 13 billion light-years from Earth, according to astronomers'

Recently, French and Italian scientists used the European Space Agency's Very Large Telescope to successfully detect the leftover ashes of the universe's first exploding stars, > This is the first direct observation of such a phenomenon by humans. Resear

The universe is a mysterious and vast world. For human beings, whether the universe can be divided is a very interesting question. However, the universe itself does not have any distinction between up and down, and everything depends on human observation

For decades, astronomers have been trying various methods to find aliens, building and launching various detectors in ground space to prepare to receive information from aliens. Human beings are not simply waiting. While searching for alien signals, they

We who live on the earth can experience a beautiful life every day. The beauty I am talking about has nothing to do with "having money or not", but the beauty on a macro level. Once you leave the near-perfect protection of the earth, you will deeply appre

Why is the night sky black? You may think this question is boring: because there is no sun! But in fact, the problem is not simple or boring at all. Many times we are accustomed to the things around us, and often do not think deeply. Let me talk about a p

The temperature goes up and down, we all feel it in our daily life. Most people should know that there is the lowest temperature in the universe, that is absolute zero, -273.15 degrees. So, is there the highest temperature in the universe? Many people may

Since birth, human beings have longed for the vast space and wanted to see the outside world. In recent decades, as scientists continue to increase the exploration of outer space, people are more eager for the world beyond the earth. However, the universe

Are there any aliens in the vast universe? Although we have not seen aliens with our own eyes, I believe that most people will firmly believe that aliens must exist. But science is rigorous, and evidence is very important. Since aliens must exist, where a

There are all kinds of celestial bodies in the vast universe. Among them, black holes are the scariest, especially supermassive black holes. Scientists have never given up on the study of black holes, and finally took the first black hole photo in 2019. B

For a century, astronomers have explored an ever-increasing extent of the universe. Less than a hundred years ago, people thought that the Milky Way was our entire universe, but now we know that the universe contains hundreds of billions of galaxies like

When people infinitely approach the speed of light, one touch can be realized, but the speed of human movement cannot reach the speed of light. Since the appearance of Einstein's "Special Theory of Relativity", human beings have a new understanding of tim

According to the Big Bang theory, our universe is 13.8 billion years old. 13.8 billion years seems to be a very long time, but according to scientists' speculation, the current universe is still very young, and the universe is still evolving towards an ex

This year, humanity has glimpsed the universe like never before, and space missions have made unprecedented leaps in unraveling its mysteries. We witnessed the first ISS mission funded entirely by space tourists. A new space-based internet service played

As soon as we open our eyes every day, we can see the vibrant physical world around us. For a long time, scientists have also firmly believed that our world is composed of matter, and atoms are the basic particles that make up matter. However, with the in

A violent big bang sprayed out all matter, forming today's bright and vast universe, and at the same time giving birth to our most wonderful life. There are tens of thousands of forms of life, but if we want to say that life is more wonderful, it belongs

Flying out of the earth and landing on other planets is not a good thing, but being able to come back is a "master"! The moon landing by the United States has already happened in the last century. With the continuous improvement of scientific cognition an

Our universe has a beginning, that is the Big Bang. The Big Bang created not only time and space, but also everything we see around us today. The universe has a beginning, so is there an end? On this issue, scientists have carried out in-depth research an

Partners who understand the Big Bang theory must know that our universe has been expanding. Maybe the big bang theory is finally proved to be a wrong understanding, but the expansion of the universe is real. Scientists have indeed discovered that the univ
