The prominences of the Sun are solar filaments of matter projected above its surface and characterizing the activity of the Sun. This activity seems to vary by up to another within a cycle.In absolute terms, solar activity is regulated by a cycle... Continue Reading →
Since its launch on March 12, 2015, NASA’s Magnetospheric Multiscale Mission, or MMS, has been making new discoveries as it flies around Earth studying magnetic reconnection — the explosive snapping and forging of magnetic field lines, at the heart of... Continue Reading →
A new study led by the University of Hawai'i (UH) at Mānoa has helped refine understanding of the amount of hydrogen, helium and other elements present in violent outbursts from the Sun, and other types of solar "wind," a stream... Continue Reading →
A new spacecraft is journeying to the Sun to snap the first pictures of the Sun’s north and south poles. Solar Orbiter, a collaboration between the European Space Agency, or ESA, and NASA, will have its first opportunity to launch... Continue Reading →
First images from the National Science Foundation's Daniel K. Inouye Solar Telescope reveal unprecedented detail of the sun's surface and preview the world-class products to come from this preeminent 4-meter solar telescope. NSF's Inouye Solar Telescope, on the summit of... Continue Reading →
NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the Sun’s atmosphere, a prominence — a large loop of material launched by an eruption on... Continue Reading →
What's happened to the Sun? Yesterday, if you were in the right place at the right time, you could see the Sun rise partially eclipsed by the Moon. The unusual sight was captured in dramatic fashion in the featured image not only directly,... Continue Reading →
In August 2018, NASA's Parker Solar Probe launched to space, soon becoming the closest-ever spacecraft to the Sun. With cutting-edge scientific instruments to measure the environment around the spacecraft, Parker Solar Probe has completed three of 24 planned passes through... Continue Reading →
