SCIENTISTS HAVE DEVELOPED A NEW TECHNIQUE THAT COMBINES OBSERVATIONS OF POLARIZED LIGHT AND SOLAR WAVES TO MEASURE THE SUN’S CORONAL MAGNETIC FIELD MORE ACCURATELY AND ROUTINELY, IMPROVING OUR ...

The National Solar Observatory (NSO) is the national center for ground-based solar physics in the United States (www.nso.edu) and is operated by the Association of Universities for Research in ...

Space weather refers to the day-to-day strength of X-ray photons, charged particles, and magnetic fields that flow from the Sun and interact with the Earth’s magnetic fields, atmosphere, and ...

Coronal loops are bright curving structures arcing above the surface of the Sun. Driven by the looping lines of the Sun’s twisted and powerful magnetic fields, these arcs of plasma are usually, but ...

The GONG facility of NSO continually produces solar full-disk images centered on the H-αspectral line at a wavelength of 6562.8 Åin air. The image format is 2048 x 2048 pixels. The images are taken ...

The central mission of the Visible Tunable Filter, VTF, is to spectrally isolate narrow-band images of the Sun at the highest possible spatial and temporal resolution from the DKIST telescope. The ...

Soaring nearly two-miles, or three kilometers, above the Pacific Ocean, Haleakalā is Maui Island’s largest volcanic mountain and a near perfect place for solar astronomy. Haleakalā is a high-elevation ...

The mission of the Cryo-NIRSP is to take advantage of the full coronagraphic capabilities of DKIST to observe both the near-limb and off-limb corona out to 1.5 Solar Radii, and, additionally, leverage ...

The Sun is a star, a medium-sized star. But how big is “medium”? Well, the Sun’s diameter is the same length as 109 Earths lined up side by side. That’s about 865,000 miles! That means that one ...

In a groundbreaking new study, a team led by scientists from the U.S. National Science Foundation (NSF) National Solar Observatory (NSO) has captured the sharpest-ever view of the Sun’s surface, ...

The Operations Building is the multi-story structure attached to the telescope enclosure that houses the control room, instrument preparation lab, mirror coating facility, mechanical equipment room ...

Tree rings, ice cores, and cosmogenic isotopes provide clues to past solar activity – and how it may have influenced past climate events Total solar irradiance, the output of light energy from the Sun ...
