A Bright Beginning: Maui High School Students Get a First Look Inside the NSF Inouye Solar Telescope The NSF National Solar Observatory and Maui Economic Development Board Host a Pilot High School Visit to the World’s Most Advanced Solar Telescope, Laying the Groundwork for Future Student Tours

Two Eyes on the Sun: Unveiling Solar Dynamics with Coordinated Observations In October 2022, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope and the European Space Agency (ESA) Solar Orbiter carried out their first coordinated campaign, capturing a decaying solar active region from two perspectives. Together, their instruments produced open-access, high-resolution datasets that reveal intricate details of coronal structures, small-scale flares, and plasma flows. These joint observations not only showcase the potential of stereoscopic solar imaging but also open fresh avenues for tackling long-standing questions about the Sun’s atmosphere dynamic behavior.

The Sun’s Atmosphere Pulses With Hidden Twisting Waves Using the world’s most powerful solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope, built and operated by the NSF National Solar Observatory (NSO) near the summit of Maui’s Haleakalā, scientists have been able to uncover the presence of elusive torsional Alfvén waves—tiny back and forth magnetic twists rippling through the Sun’s outermost atmospheric layer, the corona. Long suspected but never clearly observed, these small-scale waves continuously twist solar magnetic fields, and may help explain both how the corona stays so hot, and how the stream of charged particles that flows outward from it, known as the solar wind, is powered. At millions of degrees hotter than the Sun’s visible surface, which is only about 10,000 °F (or 5,500 °C), the reason for why the corona is so hot remains an unsolved astrophysical mystery.

Sun’s Fireworks: How the Inouye Solar Telescope Is Revealing the Secret Life of Solar Flares Using the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope, scientists have captured the most detailed view of solar flare “ribbons”—bright streaks on the Sun’s surface created during powerful eruptions. In these ribbons, they discovered tiny, regularly spaced hot spots just a few hundred kilometers wide, called ribbon blobs, that are far more dynamic than their surroundings. These blobs may form when solar magnetic fields snap and reconnect in many small bursts, a process that helps drive the flare’s explosive energy. By revealing such fine-scale details across multiple layers of the Sun’s atmosphere for the first time, the study offers fresh clues to how flares work and could improve forecasts of solar storms and space weather that affect Earth’s technology.

The National Solar Observatory (NSO) budget is slated to be cut by 54% with the 2026 presidential budget request.

With the 2026 presidential budget request, #NSO @nso.edu.web.brid.gy would see a 54% cut. This will destroy the future of #heliophysics. The budget will make #DKIST inoperable.

NSF's National Solar Observatory: Unlocking the mysteries of the Sun and its effects on Earth NSF's National Solar Observatory (NSO) is the national center for advancing knowledge of the Sun as the dominant external influence on Earth.

#NSO base funding iwould decrease from $6M to $4M, endangering #GONG. #DKIST proposed budget of $13M, compared to the $32M needed. Other NSO programs at high risk due to the proposed cuts include Solis, ngGONG, historic NSO data, the Sunspot DST facility, the DKIST Ambassador Program and much more.

World's largest solar telescope reveals unprecedented photo of the sun The Daniel K. Inouye Solar Telescope, the world's largest solar telescope, can see the sun in unprecedented detail. Here is the first image from its newly-activated camera.

Woo hoo!! Go #DKIST and VTF!

Massive solar eruption carves 60,000-mile-long 'canyon of fire' into the sun on Halloween night A powerful explosion from the sun briefly opened up an enormous valley on the solar surface that was more than twice as wide as the contiguous U.S. and seven times longer than Earth.

Ooooooooooooh! 😲

The Sun is always fascinating, and as we approach this cycle's maximum, it's getting *really* interesting. I can't wait to see what kind of data and images like this we're gonna get out of #DKIST!!
