Welcome friends from the universe to contribute enthusiastically!

If you fly at the speed of 1 light-year per second, what will you encounter?

After flying 1 s, it will reach the Oort cloud at the outermost part of the solar system;

After flying for 8 seconds, you will see Sirius, the brightest star in the night sky;

After a 9-minute flight, you will arrive at Maoxing Cluster, the closest cluster to the Earth, with 3,000 stars.

After flying for 5 hours, you will see Stevenson 2- 18, which is the largest star known at present, and its radius is 2 158 times that of the sun.

After flying 1 day, it will reach the edge of the galaxy;

After 36 days of flight, it will reach the periphery of the local galaxy group;

After flying 15 years, you can fly out of the giant celestial body Rania Maya supercluster with a diameter of 500 million light years;

Flying for 320 years, reaching the edge of hubble volume known to mankind.

No matter how far it is, scientists don't know. ......

03

Astronomers speculate that a black hole named G 1655 is heading for the solar system at high speed and will devour everything in the solar system in the future.

At present, the black hole is 6000 light years away from the solar system. According to its running speed, it will come in tens of thousands of years. ......

04

Pluto was once the brother of the earth and the planet of the solar system.

But Pluto is very far from the sun, and a year is 248 years old.

It takes 5.5 hours for sunlight to reach Pluto (it only takes 8 minutes and 20 seconds to reach Earth).

And the average temperature of Pluto is -223 degrees Celsius, and the ground is covered with frozen ancient viruses!

In 2006, scientists redefined the laws of planets and found that Pluto was not as big as previously thought and smaller than Russia, so it was directly downgraded to a dwarf planet.

05

Mount Olympus on Mars is the highest mountain known in the solar system, with the highest point of 2 1229 meters (8848.43 meters of Mount Everest).

06

On the space station, water resources are extremely precious, so astronauts never wash clothes. Dirty clothes and rubbish are usually thrown to the ground and burned in autumn. ......

So when you see a meteor in the sky, don't make a wish. Probably just underwear and garbage.

07

The Dead Sea is famous for its high salt content (about 30% on average), and people can float on the water.

But in terms of salt content, the Dead Sea is just a younger brother, ranking third in the world:

The second place, Lake Tangjuan in Antarctica, has a salt content as high as 40%, which makes it never freeze in the frozen Antarctic all year round.

First place, Gaet'ale Pond Lake, Ethiopia, which was directly ranked first due to the earthquake in June, 5438+October, 2005/Kloc-0.

08

In Xinlintargen Town, Daxinganling, Heilongjiang Province, there is a place with the coordinate of 5213'14 "north latitude, which is read as 520 13 14. I love you all my life; East longitude 124 4 1'3 1 ",read backwards 13 1442 1, I only love you all my life.

Known as the only love coordinate point in the world!

09

Be sure to remember this grass:

Equisetum arvense absorbs gold from soil and grows.

In other words, where it grows, the gold content is relatively high, which is the favorite of gold diggers.

After going out for an outing and camping, you will know what to do!

The Amazon River is the largest river in the world (the amount of water passing through a certain section of the river in unit time)!

What concept:

The runoff of the Amazon River is five times that of the Congo River (second) and seven times that of the Yangtze River (fifth). Its tributary Madeira River is higher than the Yangtze River, ranking fourth in the world.

Because of the huge runoff, the seawater near the estuary is washed away, so the seawater within about 150 km is not salty.

Besides, there is no bridge in the Amazon River!

There is a hotel in Switzerland, which is made of ice.

All the appliances in the hotel are also made of ice.

Every spring, when the temperature rises, the hotel will melt.

It is rebuilt with ice in winter, so the hotel has a new style every year.

Friends who want to experience, just one request, don't move!
