Researchers at Big Bear Solar Observatory have tuned their adaptive optics array and achieved first light, capturing this image of a sunspot that is now the most detailed ever captured in visible light. The image was captured with Big Bear’s New Solar Telescope (NST), a brand new instrument (as the name implies) with a resolution of just 50 miles on the sun’s surface.
The NST is the precursor to an even-larger telescope, the Advanced Technology Solar Telescope (ATST), which will be constructed over the next decade, allowing Big Bear researchers to build a new kind of adaptive optics system known as multi-conjugate adaptive optics, that should provide them with a clear, distortion-free means of observing the sun from Earth in unrivaled detail.
