The sun has entered a new "solar cycle", as confirmed by the US Space Agency (NASA), which means major changes to the space climate that will consequently have impacts on electrical power networks on Earth, space satellites, geolocation devices, airlines, and spacecraft. And astronauts during their space travel.
This cycle is officially called "Solar Cycle 25", and experts say that these results should make the world ready to deal with the various problems and complications that could arise from this change in space weather.
Solar Cycle 25 has officially started in December 2019, according to a Tuesday announcement by the International Committee of Experts for the purposes of predicting the 25th solar cycle.
Because the sun is so variable, it could take up to 10 months to calculate the start time of the new cycle, which is why it was announced on Tuesday.
The sun's activity continues on a cycle of about 11 years, regularly switching from calm to active and back to calm.
These periods of activity are known as solar weather, and while their changes have been observed for hundreds of years, many of their processes and effects remain largely ambiguous.
Changes in solar weather could have wide-ranging impacts in space, as astronauts, who are not protected by the Earth's magnetic field, are likely to be exposed to dangerous amounts of radiation, and the solar cycle can cause major problems for wireless technologies on Earth. .
As such, the experts suggested that the start of the new cycle should be an opportunity to plan for the changes expected in the coming years.
As the sun heads toward its new cycle, it can cause dramatic events on its surface - giant explosions in the form of solar flares or the ejection of coronal masses.
And NASA indicated that these explosions could release "light, energy and solar materials" into space.
"We keep a detailed record of the few small sunspots that mark the beginning and emergence of a new cycle," says Frederick Clitt, Director of the Global Data Center for Sunspot Index and Long-Term Solar Meteorology.
Scientists expect that activity will continue until July 2025, when the sun reaches its expected peak.
They indicated that this session is expected to be similar to the previous session, which was below average.
But researchers say this does not mean there are no risks.
"Just because it is a lower solar cycle than average, this does not mean that there is no risk of extreme space weather. The impact of the sun on our daily life is real and there," says a sun physicist at the National Oceanic and Atmospheric Administration Space Weather Prediction Center.
