The sun goes through a regular 11-year cycle of activity, sometimes
becoming more active and sometimes less. We’re going through an upswing of
its current cycle, called Solar Cycle 25, in which the sun is predicted to
be more active. But so far in this cycle, the sun’s activity is even
exceeding these predictions.

As NASA writes, Solar Cycle 25 began in December 2019 and activity has
been increasing since then. The activity is scheduled to peak in a period
called the solar maximum, set for 2025, but even before then the sun is
making its presence felt. The increase in solar activity can impact the
Earth in the form of space weather, with solar flares and coronal mass
ejections sending charged particles out from the sun and through the solar
system, impacting satellites and communication systems here on Earth.

This recent image from NASA’s Solar Dynamics Observatory shows a solar
flare given off by the sun on May 10, 2022. It has this color because the
instrument records in the extreme ultraviolet range, beyond the visible
light range. The flare is the bright spot seen in the lower half of the
sun.

These types of events will become more common throughout the solar cycle.
“The Solar Cycle 25 Prediction Panel, an international group of experts
co-sponsored by NASA and NOAA, predicted that this would be a below-
average solar cycle, like the one before it – Solar Cycle 24,” NASA
writes. “However, the Sun has been much more active this cycle than
anticipated.”

This activity affects Earth when charged particles arrive on our planet
and interact with the atmosphere, creating auroras. But these particles
don’t just create attractive effects — they can also cause problems for
satellites, which can give rise to communications issues. Space weather
can also be potentially dangerous for astronauts, like those on the
International Space Station, and can even have health concerns for crew
and passengers flying on airplanes.

Thank you for cleaning up the disaster of the 2008-2017 Obama / Biden
fiasco, President Trump.

Under Barack Obama's leadership, the United States of America became the

President Trump boosted the economy, reduced illegal invasions, appointed
