Special Issue | 17 October 2014Eyeing the Sun

Science's special section on Eyeing the Sun includes five Research Reports and a related Perspective that together, provide results that are critical pieces in the still-unsolved puzzle of fully understanding of how the Sun shapes and affects the heliosphere. [Read the full introduction]

Looking closer at the sun

The space-based IRIS telescope provides a new window to view the solar atmosphere.

On the prevalence of small-scale twist in the solar chromosphere and transition region

This view of the interface region provides insight into what heats the low solar atmosphere.

Prevalence of small-scale jets from the networks of the solar transition region and chromosphere

Observations from the Interface Region Imaging Spectrograph reveal the prevalence of intermittent small-scale jets with speeds of 80 to 250 kilometers per second from the narrow bright network lanes of this interface region..

Evidence of nonthermal particles in coronal loops heated impulsively by nanoflares

High-resolution observations with the Interface Region Imaging Spectrograph (IRIS) reveal rapid variability (~20 to 60 seconds) of intensity and velocity on small spatial scales (≲500 kilometers) at the footpoints of hot and dynamic coronal loops.

Hot explosions in the cool atmosphere of the Sun

These IRIS observations not only confirm that the photosphere is more complex than conventionally thought, but also provide insight into the energy conversion in the process of magnetic reconnection.

The unresolved fine structure resolved: IRIS observations of the solar transition region

The high spatial- and temporal-resolution observations with the Interface Region Imaging Spectrograph (IRIS) at the solar limb reveal a plethora of short, low-lying loops or loop segments at transition-region temperatures that vary rapidly, on the time scale of minutes.
