The sun may enter a new cycle of activity this month

Clinton Wallace, director of the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, predicts that the sun could enter a new cycle of activity this month, the solar cycle 25 (CS25), Newsweek reported. However, it is not clear exactly which day will happen. The sun produces a powerful magnetic field that flips about every 11 years, meaning that at the end of each solar cycle, the north and south poles of the sun’s magnetic field will shift.

The sun may enter a new cycle of activity this month

Scientists have been tracking the solar cycle since 1755. They refer to the end period of a solar cycle as the solar minianation, during which the sun has the least activity, and the middle period of the cycle as the solar maximum period, during which solar activity is frequent. During periods of solar activity, the frequency of sunspots increases, and sunspots are dark spots that appear on the surface of the sun’s sphere of light. The last solar mini-period occurred in 2009. “Next year we will know when solar activity reaches its minimum,” Wallace said in a speech at the National Academy of Sciences on April 1. “

As the solar cycle evolves, phenomena such as solar flares and coronal mass ejections will increase, releasing a lot of energy and even affecting the Planet, NASA said. Solar flares, for example, sometimes disrupt communication systems and electronic grids on Earth.

Some cycles have a lot of solar activity, but others are relatively quiet. Scientists tried to predict how active the solar cycle would be, but they failed to do so because they didn’t know enough about the physics of the sun. Still, Wallace gave a forecast for the latest solar cycle. “We’ll see solar activity peak sometime in the summer of 2025, when we’re going to see about 115 sunspots.” Of course, this is a long-term forecast that will prove the progress of this forecast in the future. “

Although we know very little about the sun, solar probes, including NASA’s Parker, are acting as our “eyes and ears” to reveal the sun’s secrets. The probe had its “closest encounter” to date with the sun, which was 26.55 million miles from the sun’s surface. In addition, earlier this year, astronomers released the clearest imageof yet of the sun, giving us a closer look at the sun’s “face.”
