A new study reveals an aspect of Earth's long-lived theory that has finally been confirmed.
The solar system is a complex dance of celestial bodies, and Earth It shares its space with some interesting neighbors. These are the closest planets to us Venus And tuesdayThe two worlds, with their very different characteristics, have always fascinated scientists. venus, Often called Earth's “twin” due to its size and composition, it is actually a planet with a toxic atmosphere and extremely high temperatures.
venus, The closest planet, on average, is located at a distance of approx 41 million km from Earth. Despite its proximity, its hellish environment makes it hostile to life, with temperatures soaring 460°C and atmospheric pressure 92 times more than Earth.
tuesday, Rather, it is the planet that has captured the most attention in science and popular culture. About 78 million kilometers from Earth, this dry, dusty world is considered a prime candidate for future human exploration. NASA's robotic missions, etc Passion and perseveranceThe discovery of ancient rivers and lakes suggests that the Red Planet may have provided favorable conditions for life in the past.
In addition to Venus and tuesday, There is another planet that approaches Earth from time to time, although it is less considered: mercury. This small world, at an average distance of 77 million kilometers, is a rocky planet, like the surface of the Moon, full of impact craters. Due to its extreme temperature variations, its proximity sun, They make it a planet Beautiful but inhospitable.
Earth's newly discovered electric field
A recent study by NASA, Published on natures, expressed a further surprise Our Planet: A fragile presence Electric field It surrounds the earth. This field, called “ambipolar,” extends from 250 to 768 km above the Earth's surface, and plays a fundamental role in the behavior of charged particles in the atmosphere.
Found, thanks patience work, This confirmed that the electric field contained the Sun's voltage 0.5 voltsBut this is enough to overcome gravity and allow charged particles to escape into space.
A step forward in understanding Earth's atmosphere
This new electric field, a Long theory But not yet directly measured, it is crucial to better understand the mechanisms that regulate the outflow of charged particles from Earth's atmosphere. field Bipolar electricityIn fact, it plays an important role in balancing the interaction between charged particles from space and the Earth's magnetosphere, which protects the Earth's surface from constant bombardment. Harmful cosmic radiation.
Furthermore, the discovery of this electric field helps to explain phenomena such as the increase in atmospheric volume at altitude and the formation of polar auroras, which are directly affected by interactions between charged particles and particles. Earth's magnetic field.
