Explanation: Enjoying Wednesday's transit of Mercury from Dallas, Texas,
astronomer Phil Jones recorded this detailed image of the Sun. Along with a
silhouette of the innermost planet, a network of cells and dark filaments
can be seen against a bright solar disk with spicules and prominences along
the Sun's edge. The composited image was taken through a telescope equiped
with an H-alpha filter that narrowly transmits only the red light |
