The moon is in the Earth's atmosphere, according to research



  • Observations carried out by SOHO spacecraft over 20 years ago have led to a new discovery.
  • The Earth has a shell of hydrogen as part of its external atmosphere, which is called geocron .
  • Last months, shows research.

We are more connected with the moon than we understand. It turns out that the outer part of the Earth's atmosphere extends far behind the lunar orbit. In fact, it reaches twice the distance to the Moon

This discovery is the result of observations of the solar and heliospheric observatory (SOHO), a spacecraft launched in 1

995 to study the sun, controlled by the European Space. Agency (ESA) and NASA.

The measurements taken by SOHO 20 years ago received a new look in a new study, which came as a remarkable conclusion. The data showed that the geocoron hydrogen shell, which revolves around our planet, extends to 630,000 km from it. This distance is 50 times greater than the Earth's diameter

Ihor Balyukin Russian Space Research Institute, chief author of the study on this issue, explained that "the moon flies through the Earth's atmosphere."

The geocoron is where the atmosphere of the planet is exposed to the outside atmosphere. space. This is essentially a cloud of hydrogen atoms. Between 1996 and 1998, SWAN aboard a SOHO spacecraft, it was possible to use its sensors in order to follow signatures with hydrogen, thus identifying the edges of the geokoron.

"Data archived many years ago can often be used for a new science," said Bernard Fleck, a scientist at the ESA SOHO project. "This discovery highlights the value of data collected over 20 years ago and the exceptional performance of SOHO."

In addition to transforming in the sense of its own atmosphere, the discovery may be useful in the search for planets with water outside of our solar system. Detecting the presence of hydrogen in their external atmosphere can mean the presence of water vapor near the surface.
