10 photos showing the vastness of the universe

If someone tells you that the universe is very large. Ask him again: How big is it? That is a question that makes anyone hard-spoken. You can only imagine the greatness of the universe when you see all the photos below.

10 photos show the incredible greatness of the universe

1. The Sun is so big that it is hard to describe

We all know that the sun is very big. However, when saying how big it is, few can describe it. The image from John Brady's 'Size of Astronomical Objects' series will give you an idea of ​​the Sun's enormousness. To be honest, before scientists could calculate the size of the Sun, our small mind could hardly imagine something so big. A Boeing 747, if traveling at full speed takes 42 hours to cycle around the Earth. At the same rate, it took six months to fly around the Sun.

2. Is the Moon really as far as you think?

The distance from the Earth to the Moon is exactly 384,400km with an error of 8,030km. So is it far or near? That depends on the distance of your comparison. The moon will be very close compared to other cosmic dimensions. However, it will be a great distance if you decide to drive there. If 7 solar planets are left close together, they will be within the distance from the Earth to the Moon.

3. Looking from Mars, the Earth is just a small light

From the ground, nobody says our planet is small. Up to orbit, our house began to appear, still very majestic. Up to the Moon, the Earth looks like a small blue marble. From Mars, only a bright spot will be seen. This image was taken by NASA's Curiosity self-propelled when Mars was relatively close to Earth: about 99 million miles. At another time in orbit, the distance between two planets can multiply up to 5 times.

4. What does North America look like if placed on Jupiter's surface?

Jupiter is very big. But with this image, John Brady once again shows you how big it really is. A tornado on Jupiter's surface is also larger than in North America. In essence, Jupiter is a giant gas planet. Its temperature is very cold, allowing it to stabilize the state of hydrogen and helium. If it is closer to the Sun, the temperature rises, hot gases will fly away.

5. Suppose you swapped the Moon for Saturn

The author of the picture is Ron Miller, who replaces the Moon in the picture of "Death Valley" with different planets in turn. In the case of Saturn, it will take up most of the sky. It will even obscure the Sun for a long time. The consequence is unimaginable if that is true.

6. A comet falls to Los Angeles

This is the comet with the code name 67P / CG that the probe Philae landed on in November last year. In space, its 3.5 mile diameter really does not tower. However, if it falls to Los Angeles, it is something hard to imagine.

7. Pluto is not on the boundary of the Solar System

Many people imagine that the Solar System ends at the orbit of Pluto because the maps only draw there. This is completely wrong. Far from Pluto's orbit, the true fringe of the Solar System is the Kuiper belt. Even bigger, it's Oort Clound, the cloud is composed of gas dust, giant jelly and comets. It is the remnant of the Sun's formation. Beyond the Oort cloud with its size doubling distance, you will come across the closest star.

8. Super-giant stars

Once you leave the Solar System, you will no longer be sad to measure the size of planets. Now only talking about stars. Where does our Sun stand when compared to other stars? Again, size is not defined by human imagination.

9. All you see in the sky is just in this circle

The stars are already very large, however, galaxies are much larger. This image is our galaxy. With the naked eye when looking up at the night sky, you only see the bright spots in the yellow circle. The farthest stars at the edge of the circle can only be seen when you are in the southern hemisphere with the most ideal conditions. For many other locations, maybe your city, the circle will be much smaller.

10. Our galaxy is just one of 100,000 light spots here

Again, the vastness of the universe is unimaginable. Our galaxy is just one of the other galaxies out there. This is just a map made by scientists with 100,000 nearest galaxies. It is called the Laniakea super galaxy. This galaxy's super pants are made up of many branches, our galaxy lies on its distant branch. A super galactic armor bordering us, Perseus seems to have opposite branches. Between two super pants is an unimaginable distance.
