A coronal mass ejection, or CME, erupting into space on August 31, 2012. Pictured here is a blended version of the 171 and 304 angstrom wavelengths taken from the Solar Dynamics Observatory. Note: the Earth is not this close to the sun, this image is for scale purposes only. Credit: […]

The chromosphere, photographed during the 1999 total solar eclipse. The red and pink hues – light emitted by hydrogen – earned it the name chromosphere, from the Greek “chrôma” meaning color.

Scientists used image processing on high-resolution images of the Sun to reveal distinct “plumelets” within structures on the Sun called solar plumes. The full-disk Sun and the left side of the inset image were captured by NASA’s Solar Dynamics Observatory in a wavelength of extreme ultraviolet light and processed to […]

The transit lasted about 30 minutes, between 12:56 and 1:25 a.m. ET. During this time, the […]

ANIMATION Researchers from the Moscow Institute of Physics and Technology (MIPT) have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle flux coming from […]

The Borexino research team has also succeeded in detecting neutrinos from the sun’s second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time.

ANIMATION Solar Orbiter’s latest results show that the mission is making the first direct connections between events at the solar surface and what’s happening in interplanetary space around the spacecraft. It is also giving us new insights into solar ‘campfires’, space weather, and disintegrating comets. “I could not be more […]

Images of the sun captured by the IRIS mission show new details of how low-lying loops of plasma are energized and may also reveal how the hot corona is created.
