NASA captured an image on Oct. 8, 2014 of the active regions on the sun resembling something like a Jack-o’-lantern’s face. This spooky photo was captured by NASA’s Solar Dynamics Observatory, or SDO, which watches the sun at all times from its orbit in space. These active regions in this photograph appear brighter due to them emitting more light and energy than their surrounding areas.

These active regions are markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. It also blends together two sets of extreme ultraviolet wavelengths at 171 and 193 Ångströms, which are normally colorized in gold and yellow, to create a particularly Halloween-like appearance.
