The sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case ...

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...

A strong geomagnetic storm is forecast for Tuesday, according to the National Oceanic and Atmospheric Administration's Space ...

From the 1980s thru 2008, scientists observed that nuclear activity inside the Sun was continuously trending downward, and it was expected that this would continue. However, a new study by the ...

The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its core fuses hydrogen atoms into helium, fueling the cosmic fire that ...

An idea about the sun’s magnetic field called the terminator model could help predict dangerous space weather more accurately ...

NASA has drafted its Mars rover Perseverance to help monitor the sun’s activity. Every day for the next two months, the rover will image the sun with its Mastcam-Z cameras, capturing crucial ...

Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar flares, and coronal mass ejections. This peak is anticipated around mid to late ...

After solar activity spent several decades on the decrease, the number of sunspots, flares and coronal mass ejections is once again on the increase. The sun has grown increasingly active over the past ...

When solar activity reached an all-time low in 2008, astronomers reasonably figured the Sun was entering into a period of historically low activity. They were wrong. New research published September 8 ...

It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research. The Sun has become increasingly active since 2008, a new NASA study shows.
