Why is it that the starry sky that can be seen on the ground cannot be seen in space?

Because 79% of the Earth's surface is oceans and 21% is land. And the sea water is blue, and we see only a small part of it on the land of the earth, so it is not as blue as it stands out from space.

On Earth, you can't see space during the day, but you can see space at night. During the day, the atmosphere scatters sunlight and makes it impossible to see the darkness of space.

Mars and Venus both have atmospheres. The atmosphere of Mars is completely different from the composition of the Earth's atmosphere, making it unsuitable for life. If you live there, you must have oxygen**.

The Sun, Earth, Moon, Jupiter, Mars, etc., can be seen in space.

1. The sun. The sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

2. Earth. Earth is the third planet in the solar system from the inside and outside, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, about 100 million kilometers (1 astronomical unit) from the sun. The Earth rotates from west to east while revolving around the Sun.

3. The moon. The moon is a spherical celestial body that orbits the Earth and is the Earth's only natural satellite.

In Chinese, it is commonly known as the moon or moon, and in ancient times, it was also called Taiyin, Xuantu, Chanjuan, and Yupan. The Moon is the fifth largest moon in the solar system, with an average radius of about one kilometer, which is twice the radius of the Earth.

4. Jupiter. Jupiter is the fifth closest planet to the Sun and the largest planet in the solar system, the ancients have known this planet for a long time, and the Romans named the planet after the main god Jupiter.

5. Mars. Mars (English: mars; Latin:

martis；Astronomical symbol: ) is the fourth closest planet to the Sun and the second smallest planet in the Solar System after Mercury, and is one of the four terrestrial planets in the Solar System. In ancient Europe, Mars was called Mars, the god of war in ancient Roman mythology, also known as the "Red Planet".

Because the average density of dust in the universe is extremely low and cannot play a significant role in refraction, the slightest wisps of sunlight through the clouds cannot be seen in space, nor can the so-called light be seen, but the light itself still exists.

Sunlight, broadly defined, is electromagnetic radiation from all spectrum of the sun. On Earth, sunlight is obviously the solar radiation that is filtered by the Earth's atmosphere above the horizon and onto the Earth's surface.

When solar radiation is not obscured by clouds, it is often referred to as sunlight when it is directly illuminated and is a combination of bright light and radiant heat. The World Meteorological Organization defines "sunshine hours" as the irradiance of sunlight directly received by an area at more than 120 watts per square meter.

So can you see the sun in outer space? The sun is a star, and if you can see the sun, you can also see other stars, and the sun is the biggest "star".

Stars can be seen in space. Stars can be seen on Earth because the light emitted by the stars is perceived by our eyes. Humans can see things because light enters our eyes, and we can see stars on Earth because "starlight" enters our eyes.

It has nothing to do with the atmosphere. In fact, the atmosphere is instead stargazing.

According to the ** and rumors circulating on the Internet, outer space is pitch black and there are no stars in sight, and Armstrong said that he can't see stars in space. This is because there are no stars to be seen during the day on the Moon, but the sky is dark, and this is because the Moon, unlike the Earth, has no atmosphere and no scattering; The moon's daytime sunlight is very bright and obscures the starlight.

Why can't I see stars in outer space? Know.

What can be seen in space can be described in space, or you can describe the scene on Earth in space.

1. The Himalayas.

The world's tallest mountain can also be seen from space. The highest mountain range separates the Indian subcontinent from the Tibetan Plateau, where Mount Everest, the highest mountain in the world. The Himalayas include hundreds of mountains that rise above 7,200 meters above sea level.

Many areas of this mountain range are also sacred in Hinduism and Buddhism.

2. Amazon River.

The 4,000-mile-long Amazon River and its tributaries can also be seen from space. This photo** was taken by an ISS crew member in 2006. In this case, it forms a long network, like a line that can be seen from space.

In space images of the Amazon River, the color of the water appears to be very dark due to the soil of the lowland forest.

3. Ganges Delta.

The Ganges Servic Delta is the largest delta-forming area in the world and can be found in the Bay of Bengal, parts of Bangladesh, and the Bay of West Bengal in India. It covers an area of 220 miles, and this amazing geographical feature can also be seen from the Earth's orbit. When the river is empty, it is possible to see a large amount of sediment in this area.
