Geminids 2025: The year's best meteor shower is coming, with a second shower hot on its tail

Recent observations indicate that a weak spot in Earth's magnetic field is expanding, but scientists assure that this phenomenon does not pose a threat to life on the planet. The magnetosphere, which has undergone significant changes throughout Earth's history, continues to protect the planet from harmful space weather.

A massive sunspot complex, identified as AR 4294-4296, has emerged on the sun and is currently facing Earth. This sunspot is comparable to the one that caused the Carrington Event in 1859, although it remains inactive at this time.

December's 'Cold Moon' rose on December 4, 2025, marking the final full moon of the year as it approached its closest point to Earth in its monthly orbit. This celestial event, known for its striking appearance, captivated stargazers around the world.

In November, a rare solar super-flare resulted in a significant spike in cosmic radiation levels in Earth's atmosphere, reaching the highest levels recorded in nearly 20 years. This event underscores the dynamic nature of solar activity and its direct impact on our planet's environment.

The Geminid meteor shower, known for its bright and colorful shooting stars, is currently active, having begun on December 4, and is expected to reach its peak on the night of December 13-14. This annual celestial event is one of the highlights of the meteor shower calendar, attracting skywatchers worldwide.

Recent research suggests that the moon's formation may have resulted from three significant impacts during Earth's early history, challenging the traditional single-impact theory. This three-impact model could provide a more comprehensive understanding of the moon's origins and the dynamics of the early solar system.

A geomagnetic storm is expected to allow visibility of the northern lights across 15 states, from Alaska to New York, on December 3. This phenomenon is driven by a rapid solar wind and an incoming coronal mass ejection that will impact Earth's magnetic field.
