New and Remarkable Details of the Sun

This image was taken with the visible imaging spectrometer on May 22, 2013, in H-alpha line center by the New Solar Telescope (NST) at Big Bear Solar Observatory (BBSO), Calif. The lawn-shaped pattern shows ultrafine magnetic loops rooted on the photosphere. The telescope is currently being upgraded to include the only solar multi-conjugate adaptive optics system to correct atmospheric distortion over a wide field of view, as well as the only fully cryogenic solar spectrograph for probing the sun in the near infrared. Other instruments have been brought on-line since 2009, to enable the NST to probe the sun with its full scientific capabilities for measuring magnetic fields and dynamic events using visible and infrared light.

Researchers at NJIT's Big Bear Solar Observatory (BBSO) in Big Bear, CA have obtained new and remarkably detailed photos of the Sun with the New Solar Telescope (NST). The photographs reveal never-before-seen details of solar magnetism revealed in photospheric and chromospheric features.

"With our new generation visible imaging spectrometer (VIS)," said Wenda Cao, NJIT Associate Professor of Physics and BBSO Associate Director, "the solar atmosphere from the photosphere to the chromosphere, can be monitored in a near real time. One image was taken with VIS on May 22, 2013 in H-alpha line center. The lawn-shaped pattern illustrates ultrafine magnetic loops rooted in the photosphere below."
