A photo of the Sun from NASA’s orbiting Solar Dynamics Observatory reveals an enormous coronal hole, a gap in the Sun’s outer layer and magnetic field. Images released by NASA show a massive hole in the Sun, 50 times the size of Earth, which is blasting an ultrafast solar wind towards our planet. The image of the Coronal hole was taken be NASA’s orbiting Solar Dynamics Observatory... 

A giant dark hole has appeared on the sun’s flaming surface, a recently-taken NASA picture has revealed. So far, scientists are stumped by why this spectacular phenomenon, known as a “coronal hole,” occurs. “The Sun starts 2015 with an enormous coronal hole near the South Pole,” scientists of NASA’s Solar Dynamics Observatory wrote in their blog, having posted a picture of the flaming... 

A new report prepared by Aerospace Defence Forces (ADF) circulating in the Kremlin today states that the reason behind their ordering an immediate full-scale electromagnetic pulse (EMP) alert this past weekend was due to an astonishing, and as yet unexplained, 228 million kilometer (142 million mile) “plasma/electrical discharge” between the Sun and Mars [photo top left] on 19 October. According... 

An X1.6 class solar flare flashes in the middle of the sun on Sept. 10, 2014. This image was captured by NASA’s Solar Dynamics Observatory and shows light in the 131 Angstrom wavelength, which is typically colorized in teal. A powerful solar flare sparked on an Earth-facing section of the sun. A subsequent coronal mass ejection is expected to reach our planet later in the week, possibly causing... 

This NASA’s Solar Dynamics Observatory image shows a giant sunspot group on the sun, from where an X-class flare erupted on January 7, 2013. A large coronal mass ejection has reached Earth – days after the Sun sent a massive burst of solar wind and electromagnetic radiation towards our planet. While causing no major geomagnetic storm, it has produced spectacular auroras in northern Europe. The... 

Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. Scientists assumed that there were only two radiation rings around the Earth, but a recently-launched NASA probe has detected a new “temporary” belt. As radiation rings pose serious hazards, the finding have implications for future manned flights. The third belt of radioactive energy particles... 

The sun is about to get a lot more active, which could have ill effects on Earth. So to prepare, top sun scientists met Tuesday to discuss the best ways to protect Earth’s satellites and other vital systems from the coming solar storms. Solar storms occur when sunspots on our star erupt and spew out flumes of charged particles that can damage power systems. The sun’s activity typically...
