This high-resolution view captures the dynamic edge of the Sun in H-alpha light, revealing spectacular prominences arcing above the solar limb. These luminous plasma structures, suspended by magnetic fields, extend tens of thousands of kilometers into space. The twisting motion seen in the large prominence at upper right suggests a complex and active magnetic field structure.

Two active sunspot regions are also visible on the solar disk, their bright plages and dark cores surrounded by swirling chromospheric filaments. These sunspots are regions of intense magnetic activity and often serve as the source of solar flares and coronal mass ejections. The solar chromosphere, rendered here in rich detail, displays the textured pattern of spicules and fibrils that dominate its surface.

Captured on June 12, 2025, at 07:45 UTC using a dedicated solar telescope with an H-alpha filter, this image provides a dramatic look at our star's constantly changing face.
