Aug. 20 (UPI) --NASA announced Wednesday that it is deciphering the sun's behavior with help from artificial intelligence. In a press release, the National Aeronautics and Space Administration said ...

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...

China is making strides in solar exploration with an ambitious plan to launch its first solar probe, Xihe-2, to the Sun-Earth L5 point. As reported by CGTN, the mission is set to take place between ...

Solar filaments are vast clouds of relatively cool plasma, often stretching across enormous distances, held aloft by complex ...

Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.

HOUSTON—Solar activity—thought to rise and fall over 11 year cycles—has been on an incline since 2008, a NASA Jet Propulsion Laboratory (JPL)-led study says. The study points to an uptick in space ...

To reconstruct the Sun’s polar magnetic behavior over more than 100 years, an SwRI scientist first corrected anomalies in historical data from Kodaikanal Solar Observatory (KoSO) to sync with direct ...

Our sun is about five times less magnetically active than other sunlike stars—effectively a special case. The reason for this could reside in the planets in our solar system, say researchers at the ...

A new technique using tree-ring carbon data and historical records uncovered a solar event from 1200–1201 CE, offering insights into past solar activity and improving space weather predictions.

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, ...
