Despite their appearance solar tornadoes are not rotating after all, according to a European team of scientists. A new analysis of these gigantic structures, each one several times the size of the Earth, indicates that they ...
Leiden physicists found a surprising interaction between electrons and a resist layer. The resist appears to charge and discharge due to incoming electrons. Publication in Physical Review Letters.
NASA's Solar Dynamics Observatory came across an oddity that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that ...
This sequence of images shows the Sun from its surface to its upper atmosphere all taken at about the same time on Oct. 27, 2017. The first shows the surface of the Sun in filtered white light; the other seven images were ...
September 2017 saw a spate of solar activity, with the Sun emitting 27 M-class and four X-class flares and releasing several powerful coronal mass ejections, or CMEs, between Sept. 6-10. Solar flares are powerful bursts of ...
On Oct. 19, 2017, the Moon photobombed NASA's Solar Dynamics Observatory, or SDO, when it crossed the spacecraft's view of the Sun, treating us to these shadowy images. The lunar transit lasted about 45 minutes, between 3:41 ...
On July 5, 2017, NASA's Solar Dynamics Observatory watched an active region—an area of intense and complex magnetic fields—rotate into view on the Sun. The satellite continued to track the region as it grew and eventually ...
On May 5, 2017, scientists will launch a sounding rocket 200 miles up into the atmosphere, where in just five minutes, it will take 1,500 images of the sun. The NASA-funded RAISE mission is designed to scrutinize split-second ...
Researchers are investigating novel ways by which electrons are knocked out of matter. Their research could have implications for radiation therapy.
On Oct. 19, 2016, operators instructed NASA's Solar Dynamics Observatory, or SDO, to look up and down and then side to side over the course of six hours, as if tracing a great plus sign in space. During this time, SDO produced ...
