Scientists use sunspots to predict the solar cycle and solar activity. That activity leads to space weather in the form of solar flares and coronal mass ejections that launch clouds of charged particles toward Earth, which in May created the strongest geomagnetic storm on Earth in two decades.

Representatives from NASA, the National Oceanographic and Atmospheric Administration (NOAA) and the international Solar Cycle Prediction Panel made the announcement at a news conf

With solar activity continuing into 2025, aurora watchers can use NOAA’s aurora dashboard to track potential sightings of this spectacular natural phenomenon.

The Sun has entered its solar maximum, increasing sunspots and solar activity. This phase, marked by more solar flares and coronal mass ejections, can

NASA and NOAA announced that the sun has reached its solar maximum period, a time when the sun produces more solar activity that can impact our technology on Earth.

The sun’s 11-year solar cycle has officially reached its “maximum phase,” according to a press release from multiple federal agencies.

NASA, NOAA, and the International Solar Cycle Prediction Panel have confirmed the Sun has reached solar maximum, slightly earlier than expected in its 11-year cycle. Thanks to the solar probes, telescopes,

The sun is at a point where its two poles have flipped, and NASA says that means we'll get more light shows here on Earth — including a more visible northern lights. The sun is at its "solar maximum" period,
