This work relied upon high-cadence observations from NASA’s Interface Region Imaging Spectrograph, or IRIS, and the Swedish 1-meter Solar Telescope in La Palma. Together, the spacecraft and telescope peer into the lower layers of the sun’s atmosphere, known as the interface region, where spicules form. The results of this NASA-funded study were published in Science on June 22, 2017 — a special time of the year for the IRIS mission, which celebrates its fourth anniversary in space on June 26.

A computer model simulation of spicules. Spicule-like features appear as dense, cool intrusions in the hot corona, originating from the boundaries of the strong magnetic regions. (A/top half of video) Temperature and (B/bottom half of video) density maps are shown on a logarithmic color map with white magnetic field lines (A) and black contours where plasma β = 1 (B). t, time.

Observations of spicules from NASA's Solar Dynamics Observatory, or SDO. Over a few hours observation of the northern pole area of the Sun in extreme ultraviolet light (Aug. 3, 2010), we can see a continual frenzy of spicules.
