Humans can't even fly out of the solar system, so how do scientists know the whole picture of the Milky Way? Guess

A panoramic look at the Milky Way

What does the Milky Way look like?

We can't drill into the solar system, so how do scientists know what the Milky Way looks like? It turned out that it was not based on speculation and imagination, but through systematic observation and analysis.

Scientists look at other galaxies and find that they can be roughly divided into several types, including elliptical galaxies, spiral galaxies, barred spiral galaxies, etc. By analyzing the planetary spectrum, it is also possible to understand the atmospheric composition of other planets.

And what about our galaxy? Based on the large number of stars observed and their distance and position with the Earth, scientists used computers to simulate the general structure of the Milky Way.

We now know that the Milky Way is a barred spiral galaxy with four main arms, and the solar system is within the Orion arm in the marginal region, about 26,000 light-years from the galactic center. This model has been overtweaked before, from the original spiral galaxy to the current barred spiral galaxy, and the scale has also increased by about 50%.

Can you see the whole Milky Way with the naked eye?

You take a picture of the train itself on the train, as if we are inside the Milky Way and want to see the whole galaxy. But even if we can't see it with our own eyes, we can get information in other ways.

For example, with radio telescopes, it can detect the density, magnetic field, temperature and other information of celestial objects, and the signal can be converted into voltage to get a complete picture. This data can then be calculated by computers to create a more accurate map of the structure of the Milky Way.

Of course, this does not mean that humanity will stop there and continue to work hard to explore the unknown universe beyond the Milky Way. While the speed of light limits the speed of exploration, scientists are also thinking of ways to break through the speed of light. We must believe that as long as we do not give up exploration, we will one day be able to cross the boundaries of the galaxy and overlook the panorama of this vast starry sky.

What do you think of human perception of the universe?

After all, human beings are small, and it is indeed not easy to understand the panorama of such a vast universe as the Milky Way. But after generations of scientists, our understanding has evolved from vague speculation to a rough sketch of what the Milky Way looks like.

This stems from the never-ending curiosity and desire to explore the unknown. Just like those pioneers, even without a telescope, they can deduce the laws of planetary motion, which shows how great human wisdom is.

Although we have not yet been able to fly out of the galaxy in person, it is through the launch of probes and other methods that we have been able to enrich our understanding of the universe step by step. As someone said, it's not the destination that matters, it's the process of discovery.

So, let's be proud that humanity has come so far! Maybe one day, we will actually be able to see the full extent of the Milky Way with our own eyes. But until then, let us continue to humbly explore the mysteries of this vast universe with awe.

The way of the "eye" of the Milky Way

We don't see the full extent of the Milky Way, but scientists are trying to expand our understanding of the starry sky in a variety of ways.

For example, radio telescopes are used to detect the density, magnetic field, temperature and other information of celestial objects, and then the overall structure of the Milky Way galaxy is reconstructed through data analysis. This is indeed a very effective way to "watch remotely".

At the same time, we can also deduce what the Milky Way might look like by studying the characteristics of other galaxies. For example, the observation of different types of galaxies, including elliptical galaxies, spiral galaxies, etc., provides a reference for us to outline the basic outline of the Milky Way.

However, the most amazing thing is the achievements of those pioneers who were able to discover the laws of planetary motion with the naked eye and mathematical deductions. Imagine a time when there were no telescopes, but you could see the mysteries of the universe, and it was truly awe-inspiring!

In today's era, we already have more advanced means of observation and computing power. Through cutting-edge technologies such as satellites and probes, we can even look beyond the Milky Way, expanding the boundaries of human exploration.

While there are still many technical bottlenecks to be achieved to realize the dream of flying out of the galaxy, scientists are working tirelessly to find new ways to break through the speed of light. You know, as long as we don't give up exploration, even dreams that seem like a fantasy will one day become a reality.

So let us continue to appreciate and learn from the achievements of these scientific pioneers with reverence. Because it is their spirit of exploration that allows us to step by step to the boundary of the universe and get a glimpse of this boundless starry sky.
