evidence: NASA and the National Oceanic and Atmospheric Administration (NOAA) will discuss the Sun’s activity and the progression of Solar Cycle 25 during a media teleconference at 2 p.m. EDT, Tuesday, Oct. 15. Tracking the solar cycle is a key part of better understanding the Sun and mitigating its impacts on technology and infrastructure as humanity explores farther into space. During the teleconference, experts from NASA, NOAA, and the international Solar Cycle 25 Prediction Panel, which is co-sponsored by both agencies, will discuss recent solar cycle progress and the forecast for the rest of this cycle. [...] The Sun goes through regular cycles of activity lasting approximately 11 years. During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation, all of which create conditions known as space weather. Space weather can affect satellites and astronauts in space, as well as communications systems such as radio and GPS — and power grids on Earth. When the Sun is most active, space weather events become more frequent. Solar activity, such as the storm in May 2024, has sparked displays of aurora and led to impacts on satellites and infrastructure in recent months.
