Earth's atmosphere extends far beyond the moon, scientists find



The Earth and its geocorroin, captured in 1972 by a camera operated by Apollo astronauts 16 on the Moon. The Earth's atmosphere extends past the Moon much further than previously thought, says a new study published in Space Physics .

When the outermost parts of the atmosphere merge with cosmic space, it emits a cloud of hydrogen atoms called the geocorrone. According to the authors of the study led by Igor Ballukin of the Russian Institute of Space Studies, this layer of gas reaches 50 times the diameter of the planet.

This extends the reach of the earth's atmosphere to approximately 330,000 miles (more than six times) than previously estimated by the Southwest Research Institute and makes the moon almost halfway to where the outer edges of the geocoron. 1

9659005] "The moon flies through Earth's atmosphere," said Igor Balukkin, the lead author of the report presenting the results, in a press release from the European Space Agency (ESA).

The Earth's atmosphere extends almost twice as far from the moon. Observations were captured by SOHO (a solar and heliosphere observatory), a satellite located approximately 930,000 miles from the earth's surface of the planet facing the sun. And they were made between 1996 and 1998, shortly after the satellite started when the SOHO satellite had a good perspective to capture an ultraviolet picture of the Earth's atmosphere using sensors that can make a map of the geoconron.

do not know about it until we have left the observations made more than two decades ago, "Balukin said. Researchers stress that data collected years ago can be used for new science. For example, they said the findings could have implications for researchers looking for other planets that have water tanks.

Planets that have hydrogen in their exospheres are more likely to have water on their surface. Scientists looking for exoplanets that could absorb liquid water, the main ingredient for life we ​​know, can search for hydrogen in the geocuron of the planets as a means of bringing out water. Earth is a great benchmark for this type of study.

Who knows? Perhaps hydrogen vapor will be the secret to finding a planet to live if we have to have a new one.
