The Inouye Solar Telescope is designed to operate for 44 years, which should cover four of the sun's roughly 11-year solar cycles. And in that time, its suite of instruments will likely change.

A narrow-band image of the Sun at a wavelength of λ=588.9nm, that of a well known solar sodium line also known as the “NaD line.” The image was acquired during recent first light efforts with ...

The world's largest solar telescope has reached an important milestone. The data published now were obtained during the technical commissioning of the instrument. The world's largest solar ...

Spaces like the massive McMath-Pierce Solar Telescope that actually proved that water vapor exists on the sun will be reworked to invite guests to explore exhibit after interactive exhibit.
