What Venus hides is life? These extraordinary images manifest the reality of Venus, one of the planets closest to Earth.

Venus, is the planet known with the passionate names of “The Morning Star” , “The Morning Star”, and as the “Goddess Aphrodite” the goddess of Love, among some appellations. And although it is not a star, it is the orb closest to Earth, and also the brightest and most visible planet in the sky.

It had always been thought that Venus could have been a tropical paradise millions of years ago because its dense clouds of sulfuric acid that roden the planet make it impossible to clearly observe its surface from the planetary exterior.

Only the hostile reality of this sister planet was known when in the 1960s certain scientists were able to measure its extreme temperatures, and the environment so incompatible with life.

Anyway, it has always been in the thought that Venus could once have had oceans, coasts, beaches, lakes and above all vegetation, but that when its atmosphere evaporated, for unknown reasons, the temperature increased drastically until it became the planet what is today

Have you ever visited Venus?

The most surprising thing about Venus was when at the time of the 80s, satellites of the Soviet Union fulfilled the programmed space mission and settled on the extension of the Venus Planet, reporting incredible and spectacular images of its surface .

 

What would natural sounds be like or not on Venus?

Although humanity knows approximately how the Solar System is formed, it does not have knowledge about the types of sounds that the planets emit, nor the natural sounds or not that would generate the different atmospheres.

According to the University of Southampton in the United Kingdom, by studying the natural sounds on several planets: winds, lightning, etc., they came to the conclusion that the human voice on Venus would have a severe sound as it happens when inhaling helium gas that the voice It is more acute.

This is due to the fact that the tone of a voice penetrates the dense atmosphere of Venus and the vocal cords vibrate more slowly and as a consequence the whistling voice emerges.

 

Why does Venus turn in the opposite direction to the rest of the Planets?

The worlds of our Solar System rotate mainly on the same axis and in the same direction around the Sun, clockwise clockwise, except Venus and Uranus that revolve around the Sun in a different direction, that is, they rotate in the same way as clockwise, clockwise.

What are the days on Venus and its planetary inclination?

Among other more surprising singularities of Venus is that the Venusian day is much longer than its own year, or return to the Sun, and the correspondence would be:

– 01 year of Venus would be equivalent to 225 Earth days.

– 01 Venus day would be 117 Earth days.

The daily duration is so long because its rotation is excessively slow when turning on its own axis. It is the slowest turn between the four rocky planets along with Mercury, Earth, and Mars that also rotate rather slowly compared to other major orbs, although the slowest rotation of all the planets in the Solar System is that of Venus.

Among other curiosities is its inclination of the axis which is about 177º , which shows that its rotation is almost in the opposite direction to that of its orbit.

What general characteristics does Venus have?

That the Diameter of Venus is 12,104 km, almost as big as Earth’s. It has a mass of 4.87 x 10 ^ 24 kg (81.5% of the Earth). That Venus does not have satellites, rings or moons. That the distance of its orbit is 108,209,475 km (0.73 AU). That its period of its orbit is 225 days. And that the average temperature of its planetary surface is 462 ° C, making it the hottest planet in the Solar System.

The atmospheric pressure on Venus is 92 times greater than that on Earth. But its size and mass are very similar to Earth .

The planetary atmosphere has so much pressure that its surface could be almost flat, and the experience on its surface would be equated to descent or immersion in the depths of the terrestrial seas.

Venus is often called the twin of Earth because they are similar in size and mass, with a difference of about 638 km in diameter between the proportions of Venus and Earth. Both planets also have a central core with a molten mantle and a crust.

Venus has phases because it orbits the sun within the orbit of the Earth and the planet seems to have phases like the moon. When Venus is on the opposite side of the sun, it is in full phase, while it appears in a new phase when it is between Earth and the sun.

The Italian astronomer Galileo Galilei, in 1610 AD, was the first to show these phases of Venus.

When was the existence of Venus known?

The first records of Venus appeared in the sixteenth century before Christ, and previously in the engravings made by the Babylonian astronomers.

At first, ancient astronomers conceived Venus as two different bodies . The Greeks called the two Venus Phosphorus and Hesperus , and the Romans called these two Venus planets with the names of Lucifer and Vesper . These astronomers did not understand that when the orbit of Venus around the Sun reaches Earth’s orbit, it is visible after sunset and visible before sunrise.

The Mayan civilization in 650 AD also made observations of the planet Venus.

When were the first trips to Venus?

Russian and American scientists sent different Space Missions to closely observe the planet Venus.

The Soviet Union sent the Venera-1 Space Probe that was launched in 1961 , but lost all contact with the Earth base and presumably was lost.

The United States of America also sent the Mariner-1 that was also lost when it hit the surface of Venus, and later in 1962 it sent the spacecraft Mariner-2 that could take some measurements and calculations of the planet Venus.

In 1966, the Soviet Union launched the Venus la Venera-3 space, which was the first artificial ship to land on the Venusian surface .

Finally after numerous vicissitudes between states, Russian and American, in 1982 the Soviet Union launched into space, towards Venus , the spacecraft Veneras-13 and 14. They were very lucky because it was the first time they could send the first images in color from the surface of Venus. In these first images made by the landing modules you could see the ground and small orange-brown rocks.

Later, in 1985 , the Soviets sent the ships Venera-15 and 16 with which they managed to map parts of the Venusian surface through the radar mechanism. And later the Vega-1 and 2 descended on the surface of venus.

Officially the last time Venus was visited was when the Cadillac spacecraft was sent, arriving in Venus in August 1990 . Little has transcended since then.
