For the first time in history, scientists have captured jaw-dropping images of the Sun’s elusive south pole, revealing magnetic chaos and clues about space weather, solar wind, and the Sun’s explosive...

For millennia, humans have looked up towards the life-giving Sun and sought to understand its nature. One of its earliest features noticeable before the age of technology was the presence of small dar...

Between 1982 and 2012, the 150-foot solar tower at Mount Wilson Observatory collected a vast archive of observations of the Sun’s surface. In a series of recent studies, Professor Roger Ulrich, togeth...

NASA’s Parker Solar Probe has mapped the shifting boundary between the sun and the rest of the solar system.

Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The UH-led team has developed a new artificial intelligence (AI) tool that can map the sun's magnetic field in three dimensions with unprecedented accuracy, supporting research tied to the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope built and managed by the NSF National Solar Observatory (NSO) on Haleakalā.

Astronomers have produced the first continuous, two-dimensional maps of the outer edge of the sun's atmosphere, a shifting, frothy boundary that marks where solar winds escape the sun's magnetic grasp. By combining the maps and close-up measurements, scientists from the Center for Astrophysics | Harvard & Smithsonian (CfA) showed that the boundary grows larger, rougher and spikier as the sun becomes more active. The findings could help scientists improve models showing how the sun affects Earth, and better predict atmospheric complexity for other stars.

Recreating artificial solar eclipses in space could help astronomers decipher the inner workings of our sun much quicker than if they had to wait for the celestial show on Earth.

The sun's corona—the outermost layer of its atmosphere, visible only during a total solar eclipse—has long intrigued scientists due to its extreme temperatures, violent eruptions, and large prominences. However, turbulence in Earth's atmosphere has caused image blur and hindered observations of the corona. A recent development by scientists from the U.S. National Science Foundation (NSF) National Solar Observatory (NSO), and New Jersey Institute of Technology (NJIT), is changing that by using adaptive optics to remove the blur.

The Institut für Sonnenphysik (KIS) located in Freiburg, Germany, has installed a high-precision measuring instrument for the world's largest solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope on the Haleakalā volcano located on Maui/Hawaii.
