Each of these primary moon phases marks a quarter of the lunar cycle and lasts only a moment. ... (On those rare occasions, make sure you wear solar eclipse safety glasses to protect your eyes.) ...

Scientists anticipate that the maximum phase will last another year or so before the sun enters the declining phase, which leads back to the solar minimum. Since 1989, the Solar Cycle Prediction ...

Solar activity waxes and wanes on an 11-year cycle.The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say.

If this is true, then we could already be in the declining phase of Solar Cycle 25. This solar maximum date is very different from the original prediction of July 2025.

The robotic Solar Orbiter spacecraft has obtained the first images ever taken of our sun's two poles as scientists seek a deeper understanding of Earth's host star, including its magnetic field, its ...

Just like we have a circadian rhythm, those who menstruate also have an infradian rhythm: a 28-day hormonal cycle, better known as the menstrual cycle. It's made up of four phases — menstrual ...

But the sun had been primed to put on a show as it approached the maximum phase of its 11-year activity cycle—and that high activity continues today. This solar cycle still has the potential to ...

Solar Orbiter is currently collecting information on several solar phenomena, including the sun’s magnetic field, its activity cycle, and the solar wind – a constant, high-speed stream of ...
