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, ...

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 ...

In February 2022, SpaceX launched a group of Starlink satellites into low Earth orbit. Soon after launch, many of them began falling back into the atmosphere rather than following their planned paths.

A powerful flare unleashed a severe solar storm that caused auroras and GPS disruptions on Earth.

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

Largest solar radiation storm in more than 20 years could trigger auroras on Earth - A solar radiation storm this large has ...

The storm could also impact power systems and spacecraft operations.

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 ...

NASA’s Parker Solar Probe has directly observed magnetic reconnection in the Sun’s atmosphere for the first time, confirming decades-old theories about solar explosions. This discovery bridges ...
